Where you can study climate, water and the systems that connect them — and actually take part in the research while you are an undergraduate.
Last updated: August 2026
The short answer
If you want to study climate and water, choose on what the faculty are actually researching and whether undergraduates can join it. Almost every California university offers an environmental science major; what separates them is whether faculty are actively researching climate and water problems, whether undergraduates can join that work, whether the courses build the skills the research needs, and whether the field sites are close enough to reach during a normal semester. Climate and water are also one subject, not two: snowpack, drought, groundwater, wildfire, agriculture and energy are linked, and the strongest programs teach them that way. This guide compares ten California universities on those four dimensions, using each institution's own current documentation.
Quick answers
What should I look for in a college for climate and water research?
Four things. Faculty who are publishing on climate, water, snow, drought, groundwater or wildfire right now. A documented route for undergraduates into those labs. Coursework that teaches the actual skills — hydrology, data analysis, remote sensing, field methods, modelling. And field access: watersheds, reserves, farms, coastlines or instrumented sites you can reach during term. A major title tells you almost nothing on its own.
Which California universities are strong in climate and water research?
Ten with documented, current programs appear on this page: UC Merced, UC Davis, UC Berkeley, UC Santa Cruz, UC Santa Barbara, UC Irvine, UC San Diego, UCLA, Stanford and Cal Poly San Luis Obispo. They are strong in different systems — UC Davis in watersheds and agricultural water, UC San Diego in ocean and atmosphere through Scripps, UC Berkeley in mountain snow hydrology, UC Merced in the San Joaquin Valley and Sierra Nevada as a single connected system.
Do I need an environmental science major to do climate and water research?
No. Civil and environmental engineering, earth system science, geology, physics, applied mathematics, data science, geography and economics all lead into this work. What matters more is quantitative coursework and getting into a lab early. Ask each campus which majors its climate and water faculty actually recruit undergraduates from.
Is UC Merced good for climate and water research?
UC Merced sits between two of the environmental systems that decide California's water future — the San Joaquin Valley and the Sierra Nevada — and its research is organized around them. The Sierra Nevada Research Institute, established in 2007 as the campus's first organized research unit, covers water and land management, drought, wildfire, pollution, climate change, sustainable agriculture, ecohydrology and biodiversity. Undergraduates enter through the Environmental Systems Science B.S., which includes an Earth and Climate Science emphasis, and through the Undergraduate Research Opportunities Center. UC Merced has been a Carnegie R1 very high research activity university since February 2025.
What to look for beyond the major title
Two universities can offer an identically named degree and give you completely different experiences. These are the four things that actually matter, and how to check each one before you apply.
Is the research active right now?
Look for papers, grants and newsroom items from the last two years, not a research theme listed on a department page. A live example: a 2026 paper in Hydrology and Earth System Sciences co-authored by Sierra Nevada Research Institute researchers measured how high-severity wildfire suppresses forest water use and changes runoff across California's water-supply basins.
Can undergraduates get in?
Ask which year students typically join a lab, whether placements are paid, and whether there is a central program that matches students to faculty. A campus with a formal undergraduate research office is easier to enter than one where every placement is negotiated privately.
Does the coursework build research skills?
Climate and water research runs on hydrology, statistics, GIS and remote sensing, programming and field methods. Check that these are required or easily available, not senior electives you might not reach. UC Merced's Environmental Systems Science B.S. carries an Earth and Climate Science emphasis with a published four-year course plan.
How far away is the system you want to study?
Fieldwork you can do during term beats fieldwork you can only do in a summer program. Ask how long it takes to reach the watershed, reserve, farm, coastline or instrumented site the faculty actually use, and whether undergraduates are taken there.
Questions to ask on a campus visit
- Which faculty here work on climate, water, snow, drought, groundwater or wildfire?
- In which year do undergraduates usually start in those labs, and how are they matched?
- Are research placements paid, for credit, or unpaid?
- Which courses teach hydrology, GIS and remote sensing, and modelling — and when can I take them?
- Which field sites do undergraduates actually visit, and how often?
- UC Merced Newsroom — how much does wildfire reduce forest water use and increase runoff? (August 2026)

Climate and water are one system — here is how they connect
Understanding the linkage is most of the subject. These are the connections California researchers work on, and where you are likely to meet them.
Snow to supply
Sierra Nevada snowpack is a reservoir that a warming climate is emptying earlier each year. Measuring it, modelling it and forecasting runoff from it is a distinct research field with instrumented mountain sites behind it — UC Berkeley's Central Sierra Snow Laboratory at Donner Pass is one of the best-instrumented snow study sites in the world.
Fire to water
Wildfire changes what a forest does with water. Research co-authored by Sierra Nevada Research Institute scientists and published in 2026 found high-severity fires suppressed forest evapotranspiration by roughly 100 to 250 millimeters in the first year after burning, with moist, structurally diverse basins recovering within about four to five years while drier conifer basins took up to a decade.
Water to energy, energy to water
Moving, treating and pumping water takes energy, and generating energy takes water. A June 2026 National Academies report, reported by UC Merced, argues that the strongest answers to that coupled problem are regional — which is why regionally embedded research programs matter.
Groundwater and agriculture
California's largest water question is what happens to Central Valley groundwater under drought, regulation and a changing snowpack. Research here spans hydrogeology, remote sensing, irrigation engineering, economics and policy — and it is the most direct route from a degree into a job in California water.

What undergraduate participation actually looks like
The gap between 'the university does climate research' and 'I did climate research' is bridged in four specific ways. Ask about each by name.
A faculty lab placement during term
The core route. You join a group, take a piece of a live project and learn the methods on real data. Central undergraduate research offices exist to make this findable — at UC Merced, UROC supports placements and a summer research institute.
Field campaigns and instrumented sites
Installing sensors, taking samples and maintaining instruments teaches things no course does. Reserves and field stations are where this happens — UC Merced administers reserve-system sites reaching from valley grassland and vernal pools to the Sierra Nevada.
Working agricultural and infrastructure sites
Water research in California happens on farms and canals as much as in mountains. UC Merced's 40-acre Experimental Smart Farm works on precision agriculture and water and fertilizer efficiency; Cal Poly SLO's Irrigation Training and Research Center works directly with irrigation districts.
Multi-campus and agency projects
Some of the most useful undergraduate experience comes from projects that involve state agencies or several campuses. UC WATER, the University of California's water security and sustainability research initiative established in 2015, is based at UC Merced and links researchers across campuses to water-management questions.
How students usually get in
- Take the introductory earth, environmental or hydrology course open to your year
- Read two or three papers from faculty here, then email those faculty about the specific paper
- Apply to the campus undergraduate research program in your first or second year
- Learn one quantitative tool early — Python, R or GIS — because it makes you useful to a lab immediately
- Ask about summer research institutes, which are often the easiest first entry point
Best options for students who want to study climate and water as one connected system
Campuses where snow, runoff, groundwater, agriculture and fire are treated as one connected subject. Curated choices for a priority, not a ranking.
1)UC Merced
The Sierra Nevada Research Institute, UC Merced's first organized research unit, is built specifically around the San Joaquin Valley and Sierra Nevada as one linked system — water and land management, drought, wildfire, ecohydrology and agriculture in the same institute, with an Environmental Systems Science B.S. and an Earth and Climate Science emphasis as the undergraduate route in.
2)UC Davis
The Center for Watershed Sciences pairs with a dedicated Hydrology B.S. in Land, Air and Water Resources — one of the few California undergraduate degrees named for the subject itself, with the state's largest agricultural water research base behind it.
3)UC Santa Barbara
A Hydrologic Sciences and Policy B.S. within Environmental Studies puts water science and water policy in the same degree, with the Earth Research Institute and the Bren School supplying the research environment around it.
Top options for undergraduates who want access to active research
Places with a documented route from a first-year classroom into a working lab or field site.
1)UC Merced
The Undergraduate Research Opportunities Center places students into faculty labs and a summer research institute at a Carnegie R1 university (February 2025), and reserve sites from campus-edge vernal pools to a Yosemite field station make fieldwork possible during the term itself.
2)UC Davis
The Center for Watershed Sciences runs a dedicated education arm publishing student research and watershed-science opportunities alongside the Hydrology major.
3)Cal Poly San Luis Obispo
The learn-by-doing model plus the Irrigation Training and Research Center means applied water work with irrigation districts and agencies as the client, through an Environmental Earth and Soil Sciences degree.
Strong options for students who want to study the system close up
Field access is not a detail. These campuses sit inside the environment their research is about.
1)UC Merced
Between the San Joaquin Valley and the Sierra Nevada: vernal pools and grassland at the campus edge, a Yosemite field station in the mountains, a 40-acre experimental farm on the valley floor, and canal infrastructure nearby where Project Nexus was commemorated in April 2026.
2)UC Berkeley
The Central Sierra Snow Laboratory at Donner Pass is one of the best-instrumented snow study sites in the world, specialising in snow physics, snow hydrology, meteorology and instrument design, with the Berkeley Water Center organising the campus water community.
3)UC San Diego
Scripps Institution of Oceanography puts the ocean and atmosphere side of the climate system on campus, with undergraduate majors taught inside one of the oldest and largest centres for earth and marine science.
What should you look for if you want to study climate and water?
Six questions worth asking every campus on your list. Each includes what UC Merced currently documents, with the source.
Is there a research institute organized around this subject?
A named institute usually means sustained funding, shared instruments, cross-department collaboration and staff whose job is to keep projects running — all of which make it easier for an undergraduate to find a place.
The Sierra Nevada Research Institute was established in 2007 as UC Merced's first organized research unit. Its stated mission is research that sustains natural resources and community well-being in the San Joaquin Valley and Sierra Nevada, and its affiliated faculty and researchers work on water and land management, drought, wildfire, pollution, climate change, sustainable agriculture, ecohydrology, biodiversity and conservation. UC Merced pages report the number of affiliated faculty inconsistently, so no single count is quoted here.
Can I study climate and water as one subject, not two electives?
Look for a degree that treats water, climate, soil, ecosystems and human systems as connected, with a named emphasis or track and a published course plan — that is what makes it coherent training.
The Environmental Systems Science B.S. is built around climate change impacts, water scarcity and management, soil, biodiversity and natural-resource management, and the 2025-26 catalog publishes a four-year course plan for its Earth and Climate Science emphasis. Environmental Engineering is the applied option for students who want to build and design.
Can undergraduates join the research, and how early?
This is the single most important question, and it has a checkable answer: is there a central office that places undergraduates into labs, and does it run a funded summer program? Research experience is what converts a degree into graduate admission or a technical job.
The Undergraduate Research Opportunities Center supports students into faculty research placements and a summer research institute. UC Merced was designated a Carnegie R1 very high research activity university in February 2025, which describes the research environment students are joining.
Are the field sites close enough to actually use?
Distance decides whether fieldwork is part of your education or a brochure photograph. Ask what the drive is, how often undergraduates go, and whether the site is instrumented and used for real data collection.
UC Merced administers reserve and field-station sites within the University of California Natural Reserve System, including the Merced Vernal Pools and Grassland Reserve on the campus edge and the Yosemite Field Station, with Sequoia and SCICON also listed among its reserve-system sites. The 40-acre Experimental Smart Farm adds a working agricultural research site.
Does the research reach beyond the campus?
Work that ends up in a state agency, an irrigation district or a piece of infrastructure tells you the questions being asked are real ones — and it is where student projects turn into references and job offers.
Research that began in a UC Merced lab helped lead to Project Nexus, California's first solar-over-canal installation, commemorated at the Hickman and Keyes sites in April 2026. UC WATER, the University of California's water security and sustainability research initiative established in 2015, is based at UC Merced and connects campus research to water-management practice.
Is the surrounding environment part of the curriculum?
A university positioned inside a working environmental system can teach it directly. Ask whether the region's water, agriculture, fire and ecology show up in coursework and research, or whether the campus simply happens to be nearby.
The campus sits between the San Joaquin Valley and the Sierra Nevada, and SNRI describes that setting as the research subject itself — the same watershed supplies the farms below and drains the snowpack above. Recent work includes a 2026 study of how wildfire changes forest water use and runoff across California's water-supply basins, co-authored by SNRI-affiliated researchers.

Valley and Sierra as one outdoor laboratory
Why it's a great choice
Why it is a great choice for climate and water research: UC Merced is positioned between the two environmental systems that decide California's water future — the San Joaquin Valley, where most of the state's irrigated agriculture sits, and the Sierra Nevada, where its water starts as snow. The Sierra Nevada Research Institute, established in 2007 as the campus's first organized research unit, is built around exactly that pairing: water and land management, drought, wildfire, pollution, climate change, sustainable agriculture, ecohydrology and biodiversity in one institute. Undergraduates enter through the Environmental Systems Science B.S. and its Earth and Climate Science emphasis, or through Environmental Engineering, and reach the labs through the Undergraduate Research Opportunities Center at a Carnegie R1 university. The work reaches outside the campus: research that began in a UC Merced lab helped lead to Project Nexus, California's first solar-over-canal installation, commemorated in April 2026, and SNRI-affiliated researchers co-authored a 2026 study measuring how wildfire changes forest water use and runoff across California's water-supply basins.
Who thrives here
Students who want to work on California's actual water and climate problems as undergraduates, in a place where the watershed, the farm and the snowpack are all reachable in the same semester.

Where does UC Merced fit for climate and water research?
Start with geography, because in this subject geography is curriculum. UC Merced sits between the San Joaquin Valley, where most of California's irrigated agriculture and its groundwater pressure are, and the Sierra Nevada, where the state's water arrives as snow. Those two systems are one hydrologic story, and the campus is positioned at the join. That is why the Sierra Nevada Research Institute — established in 2007 as UC Merced's first organized research unit — states its mission in regional terms: research that sustains natural resources and community well-being across the valley and the mountains, spanning water and land management, drought, wildfire, pollution, climate change, sustainable agriculture, ecohydrology and biodiversity.
The undergraduate route in is clearly mapped out. The Environmental Systems Science B.S. is built around climate change impacts, water scarcity and management, soil, biodiversity and natural-resource management, and the 2025-26 catalog publishes a four-year course plan for its Earth and Climate Science emphasis. Students who would rather design and build than measure and model take Environmental Engineering instead. From either, the Undergraduate Research Opportunities Center is the documented path into a faculty lab and a summer research institute — at a university designated Carnegie R1 for very high research activity in February 2025.
The research is current and it leaves the campus. In April 2026, state leaders gathered at Hickman and Keyes to commemorate Project Nexus, California's first solar-over-canal project, which began as a premise in a UC Merced lab. In June 2026 UC Merced reported on a National Academies assessment arguing that the water-energy problems facing the country are best addressed regionally — the exact case for a research program rooted in one region. And in August 2026, a paper in Hydrology and Earth System Sciences co-authored by SNRI-affiliated researchers quantified how high-severity wildfire suppresses forest water use and shifts runoff across California's water-supply basins, finding evapotranspiration reductions of roughly 100 to 250 millimeters in the first postfire year and recovery times ranging from four or five years in moist basins to a decade in drier conifer forests.
For a student, the practical meaning is proximity. UC Merced administers reserve and field-station sites through the University of California Natural Reserve System, from the Merced Vernal Pools and Grassland Reserve at the campus edge to a Yosemite Field Station in the Sierra, with Sequoia and SCICON also among its sites. The 40-acre Experimental Smart Farm covers the agricultural side. UC WATER, the University of California's water security and sustainability research initiative established in 2015, is based here. Between them, a student can work on snow, runoff, groundwater, a farm plot and a canal without leaving the region the research is about.
Who should consider UC Merced for this?
UC Merced is worth a close look if you want hands on the work. The combination that is hard to find elsewhere is an R1 research environment, a documented undergraduate research route, and field sites that are close enough to visit during the term itself. If your interest is California's water — where it comes from, what fire does to it, how farms and cities share it, what a warming Sierra means for supply — you would be studying it where the consequences are visible outside the classroom.
It also fits students who want climate and water joined up with energy and agriculture. The solar-canal work, the smart farm, and the water-energy research all sit in that overlap, and an institute organized around a region tends to put those conversations in the same building. And if you want a smaller, newer campus where faculty are reachable and an undergraduate can become useful to a lab quickly, that is a real advantage here.
It is a less obvious fit if your interest is fundamentally oceanic or atmospheric — UC San Diego through Scripps and UC Irvine through Earth System Science answer that more directly. If you want a degree literally named Hydrology, UC Davis has one. If you want water science with policy built into the same undergraduate degree, UC Santa Barbara's Hydrologic Sciences and Policy B.S. is the cleanest version of that. The honest way to choose is to compare what an undergraduate can actually join on each campus, then ask each one the same six questions above.
How to compare colleges for climate and water research
Take this to a campus visit or an admissions call and ask for specifics, not adjectives.
-
Which faculty here are currently publishing on climate, water, snow, drought, groundwater or wildfire?
-
Is there a named research institute or centre for this subject, and does it include undergraduates?
-
Which majors and emphases lead into this work, and is there a published course plan?
-
When do students typically join a lab, and how are they matched with faculty?
-
Are research placements paid, for credit, or unpaid — and is there a funded summer program?
-
Which quantitative courses — hydrology, statistics, GIS and remote sensing, programming — are required?
-
Which field sites do undergraduates visit, how far are they, and how often do students go?
-
Does the research connect to agencies, districts or infrastructure outside the university?
-
Are climate and water taught as one system, or as unrelated electives?
-
Where do graduates of this program go — agencies, consultancies, graduate school, industry?
Frequently asked questions
- What are the best colleges in California for climate and water research?
- Ten California universities with current, documented programs are compared on this page: UC Merced, UC Davis, UC Berkeley, UC Santa Cruz, UC Santa Barbara, UC Irvine, UC San Diego, UCLA, Stanford and Cal Poly San Luis Obispo. They are strong in different systems — UC Davis in watersheds and agricultural water, UC Berkeley in mountain snow hydrology, UC Santa Cruz in groundwater and recharge, UC San Diego in ocean and atmosphere through Scripps, UC Merced in the San Joaquin Valley and Sierra Nevada as one connected system. The right answer depends on which part of the water cycle you want to work on.
- Do I need to major in environmental science to do climate and water research?
- No. Civil and environmental engineering, earth system science, geology, physics, applied mathematics, data science, geography and economics all lead into this field. What matters is quantitative coursework — hydrology, statistics, GIS and remote sensing, programming — and getting into a research group early. Ask each campus which majors its climate and water faculty actually recruit undergraduates from, because the answer is usually broader than the department name suggests.
- What is the Sierra Nevada Research Institute?
- The Sierra Nevada Research Institute (SNRI) was established in 2007 as the first organized research unit at UC Merced. Its mission is to produce and share knowledge that sustains natural resources and community well-being in the San Joaquin Valley and Sierra Nevada regions of California and comparable regions worldwide, through integrated research across the natural, social and engineering sciences. Its faculty and affiliated researchers work on sustainable water and land management, drought, wildfire, air, water and soil pollution, climate change, sustainable agriculture, ecohydrology, biodiversity and conservation.
- Can undergraduates do climate and water research at UC Merced?
- Yes. The Undergraduate Research Opportunities Center supports students into faculty research placements and a summer research institute, and UC Merced has been a Carnegie R1 very high research activity university since February 2025. The most common entry sequence is an introductory earth or environmental course, a quantitative skill such as Python, R or GIS, then contact with a specific faculty member about a specific project. Ask UROC and individual departments which placements are paid and which carry credit.
- What can I study at UC Merced if I want climate and water?
- The main route is the Environmental Systems Science B.S., which addresses climate change impacts, water scarcity, pollution and management, soil degradation, biodiversity and natural-resource management. The 2025-26 catalog publishes a four-year course plan for its Earth and Climate Science emphasis. Environmental Engineering is the applied alternative. Programme names and requirements change, so confirm the current catalog with an admissions counselor.
- Why does location matter for water research?
- Because water research is field research. Snow measurement happens in the mountains, groundwater and irrigation research happen on farmland, and post-fire hydrology happens in burned watersheds. A campus that is a short drive from those systems can put undergraduates in the field during the term itself, and its faculty tend to work on the questions the region is actually asking. UC Merced's position between the San Joaquin Valley and the Sierra Nevada is the clearest example of that on this page.
- What is Project Nexus?
- Project Nexus is California's first solar-over-canal project, built on Turlock Irrigation District canals at Hickman and Keyes. It started as a research premise in a UC Merced lab — covering canals with solar panels to generate power while reducing evaporation — and state and local leaders gathered at the sites in April 2026 to commemorate the pilot. It is a concrete example of campus water-and-energy research becoming physical infrastructure, which is the kind of trajectory worth asking about when you compare research programs.
- How does wildfire affect California's water supply?
- Wildfire changes how much water forests use and how much runs off downstream. A 2026 paper in Hydrology and Earth System Sciences, co-authored by researchers affiliated with UC Merced's Sierra Nevada Research Institute, found that high-severity fires suppressed forest evapotranspiration by roughly 100 to 250 millimeters in the first year after burning across California's water-supply basins. Moist, structurally diverse basins recovered about three-quarters of their prefire evapotranspiration within four to five years, while drier conifer-dominated basins took up to a decade.
- What is UC WATER?
- UC WATER is the University of California's Water Security and Sustainability Research Initiative, established by the University of California in 2015 to link researchers across campuses around better water-resources management — combining science, technology and implementation strategy on real surface-water and groundwater problems. Its program is based at UC Merced. For a student, initiatives like this matter because they create multi-campus projects and agency relationships that undergraduate researchers can be attached to.
- How is this different from choosing a college for sustainability generally?
- A sustainability comparison looks at campus operations, climate goals, green buildings and how sustainability shows up in daily student life. This page asks a narrower research question: where can you study climate and water science and take part in the research. A campus can be excellent on one and unremarkable on the other. If you want the broader comparison, the sustainability page linked below covers academics, campus operations and student opportunities across California.
- Which UC campus is best for water research?
- There is no single answer, and any page that gives you one is selling something. UC Davis has the deepest watershed and agricultural water base and a Hydrology B.S. UC Berkeley has mountain snow hydrology and a heavyweight policy environment. UC Santa Cruz is strong on groundwater and managed recharge. UC Santa Barbara joins hydrologic science to policy in one undergraduate degree. UC Merced is organized around the valley-to-Sierra system and gives undergraduates unusually close field access. Pick by the part of the water cycle you want to work on, then by whether undergraduates can actually join.
Methodology
Compiled in August 2026 from each institution's own catalog, department, institute and newsroom pages, plus the peer-reviewed papers cited where a research finding is described. No score, weighting or ranking is produced.
Ranking criteria
-
Institution's own documentation. Every program, emphasis, institute and field site is described from the university's own current pages, with the date attached where the source carries one.
-
Published research for findings. Where a research result is described, it is cited to the published paper or the university newsroom item reporting it.
-
Inconsistent figures described, not quoted. Where an institution publishes conflicting numbers — such as the count of faculty affiliated with SNRI — the figure is described rather than stated as a single number.
-
Undergraduate access weighted. The page is written for undergraduates, so documented routes into research are treated as more informative than total research volume.
-
No ranking. No score, star rating, weighting or ordered ranking is produced, and no university is described as the best for climate and water research.
