WEAP: Water Evaluation And Planning System User Guide (for WEAP 21)
2007The Water Evaluation and Planning System (WEAP) aims to incorporate concerns about allocation of limited water resources, environmental quality, and sustainable water use into a practical tool for water resources planning. As a database, WEAP provides a system for maintaining water demand and supply information. As a forecasting tool, WEAP simulates water demand, supply, flows, and storage, as well as pollution generation, treatment and discharge. As a policy analysis tool, WEAP evaluates a full range of water development and management options and takes account of multiple and competing uses of water systems.
