This fact sheet describes WEAP (Water Evaluation and Adaptation Planning), a software tool developed by the Stockholm Environment Institute for integrated water resources planning and policy analysis.

• WEAP is a comprehensive software tool designed for integrated water resources planning and policy analysis, used by over 50,000 users across nearly 200 countries and cited in more than 1,000 publications.
• The tool employs an integrated approach that treats water demand—including use patterns, reuse, and allocation—as equal in importance to the supply side, which includes groundwater, reservoirs, and streamflow.
• WEAP functions as a database for maintaining water information, a forecasting tool for simulating variables such as runoff, pollution generation, and instream water quality, and a policy analysis tool for evaluating management options and costs.
• Scenario analysis is a core feature of WEAP, allowing users to model the impacts of changing demographic patterns, water conservation efforts, climate change, and altered reservoir operating rules.
• The software features a GIS-based graphical interface with automatic catchment and river delineation using CMIP6 climate scenarios and elevation databases, and it can link to external models such as MODFLOW, MODPATH, and QUAL2K.
