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.

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.
SEI is building the Ventura Water Allocation Model (VWAM) using SEI’s flagship WEAP software for the Ventura River watershed in California.
SEI is designing water allocation models that explicitly represent every water right and assess the impact of in-stream flow requirements on water users.
SEI adapted WEAP to assess the needs of chinook salmon and steelhead trout in the Santa Clara Valley Water District.
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).
SEI worked with the Yolo County Flood Control and Water Conservation District to produce a Stormwater Resources Plan.
The Water Evaluation and Planning tool (WEAP) provides a comprehensive, flexible and user-friendly framework for policy analysis in water resources planning.
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.
This paper simulates policy and climate scenarios in California to inform salinity pollution management while keeping farmers in business.
This study analyses how managed aquifer recharge might affect irrigated agriculture in California's Kings Groundwater Basin during drought.
This article discusses how different climate scenarios affect the water-energy nexus in California, employing the WEAP modelling tool.
The Sacramento Water Allocation Model, known as SacWAM, mimics one of the most complex water systems in the US.
Policy-makers can now model the effect of management options on the availability of habitat and the viability of aquatic species.
RDS helps stakeholders create a shared mental model of available opportunities and potential trade-offs for various objectives.
