SEI researchers work throughout California to model complex water systems and explore sustainable management options.
The SEI US Water Program works with policy-makers and stakeholders throughout California to model complex water systems and explore sustainable management options. Using the Water Evaluation and Planning (WEAP) tool, SEI helps local, regional and state-wide agencies create a shared “mental model” of watersheds that brings diverse interests and perspectives to the table.

Project / SEI is developing the Shasta River Water Allocation Model to help evaluate potential management actions in the watershed under the California Water Action Plan.
Project / SEI is building a water allocation and hydrology model in the Upper Klamath River basin.
Project / SEI uses its flagship water modelling software, WEAP, to update the California Water Plan.
Project / SEI researchers are developing a long-range automated water forecasting tool for the California State Water Resources Control Board.
Project / SEI is working with UC Davis and the California State Water Resources Control Board to implement the Drought Emergency Regulation in the Scott River watershed.
Project / SEI is building the Ventura Water Allocation Model (VWAM) using SEI’s flagship WEAP software for the Ventura River watershed in California.
Project / SEI is designing water allocation models that explicitly represent every water right and assess the impact of in-stream flow requirements on water users.
Project / SEI adapted WEAP to assess the needs of chinook salmon and steelhead trout in the Santa Clara Valley Water District.
Project / A team led by SEI worked with water managers in California's Yolo County to prepare for implementation of the Sustainable Groundwater Management Act (SGMA).
Project / SEI worked with the Yolo County Flood Control and Water Conservation District to produce a Stormwater Resources Plan.
Tool / The Water Evaluation and Planning tool (WEAP) provides a comprehensive, flexible and user-friendly framework for policy analysis in water resources planning.
Project / The Sacramento Water Allocation Model enables policy-makers to weigh difficult trade-offs in water use, by simulating a complex water system in the US.
SEI brief / Policy-makers can now model the effect of management options on the availability of habitat and the viability of aquatic species.
Other publication / This paper simulates policy and climate scenarios in California to inform salinity pollution management while keeping farmers in business.
Journal article / This study analyses how managed aquifer recharge might affect irrigated agriculture in California's Kings Groundwater Basin during drought.
Journal article / This article discusses how different climate scenarios affect the water-energy nexus in California, employing the WEAP modelling tool.
SEI brief / The Sacramento Water Allocation Model, known as SacWAM, mimics one of the most complex water systems in the US.
SEI brief / Policy-makers can now model the effect of management options on the availability of habitat and the viability of aquatic species.
SEI brief / RDS helps stakeholders create a shared mental model of available opportunities and potential trade-offs for various objectives.
Journal article / The authors explore early classical writing from Plato and Aristotle to find a new approach to water resource planning and decision-making.
Journal article / This article describes the development of a groundwater sustainability plan for California's Yolo County, using a participatory decision-making process.
Perspective / This World Water Day, SEI Scientist Doug Chalmers reflects on how science supports conflict resolution around one of the planet's most precious resources: water
Feature / Water managers must balance the needs of aquatic habitat and human supply. SEI Scientist Doug Chalmers explains a new approach to help resolve that tension.
Feature / SEI Senior Scientist Chuck A. Young explains why California saw severe water shortages this year and how better forecasting can help alleviate those challenges.
Feature / The eWRIMS Analyzer transforms California’s water rights data into accessible reports on monthly water use in each watershed.
Feature / SEI's flagship water modelling tool helped a San Jose-area water district identify an opportunity to help protected steelhead in the wake of dam construction.
Feature / SEI is working with the U.S. Department of Energy and the California and Chinese governments to help policy-makers plan for resilient water and energy systems.
Feature / SEI's Charles Young and Stantec's Andy Draper won for their work on an unprecedented water model of the Sacramento-San Joaquin Delta.
Journal article / This article discusses how different climate scenarios affect the water-energy nexus in California, employing the WEAP modelling tool.
SEI brief / The Sacramento Water Allocation Model, known as SacWAM, mimics one of the most complex water systems in the US.
Tool / The Water Evaluation and Planning tool (WEAP) provides a comprehensive, flexible and user-friendly framework for policy analysis in water resources planning.
