The water program drives innovation in water management by developing, using, and transferring planning tools and participatory processes that promote holistic, transparent and robust decision-making.
We work on national, regional and local scales, mapping out watersheds and future conditions using SEI’s Water Evaluation And Planning System (WEAP). WEAP enables policy-makers and stakeholders to consider how management plans will affect cities, industries and farms, as well as long-neglected interests such as wildlife habitat and vulnerable communities.
Our researchers are located in all three US offices.
Perspective / SEI's Charlotte Wagner and Jonathan Green highlight an overlooked issue at the 2024 High-Level Political Forum: pollution's impact on small fisheries.
Event on 16 October – 30 October / SEI scientists will host a three-day training on WEAP, SEI's flagship water modelling software, on 16, 23 and 30 October Register today.
Past event / Learn how SEI's innovative water modelling tool allows researchers and policymakers to advance sustainable and equitable water planning.
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.
Project / SEI researchers are working on a new framework to ensure water models provide decision-makers with the tools to address poverty and inequality.
Project / SEI researchers work throughout California to model complex water systems and explore sustainable management options.
Project / SEI researchers build water models and work with stakeholders throughout Africa to explore management strategies for an uncertain climate future.
Program / SEI researchers apply a range of economic methods to explore the value of water and enable plans that foster cooperation across sectors and boundaries.
Other publication / This report explores the effectiveness of different methods to implement source water protection in cities in low- and middle-income countries.
Other publication / Cooperation in the water-energy-food-ecosystems nexus among countries sharing the Syr Darya River Basin can improve local livelihoods.
SEI brief / Policy-makers can now model the effect of management options on the availability of habitat and the viability of aquatic species.
SEI report / This report presents a pathways approach designed to foster collaboration between researchers, practitioners and stakeholders who manage and allocate water.
Project / SEI is studying the evaporation from the Lower Snake River reservoirs in the northwest United States, as authorities explore removing four dams.
Project / SEI is building a water allocation and hydrology model in the Upper Klamath River basin.
Project / SEI has provided forecasting and long-term water supply projections for Colorado Springs Utilities for nearly a decade.
Project / SEI uses its flagship water modelling software, WEAP, to update the California Water Plan.
