Providing Custom Information to Water Resource Managers


Attention is increasingly focused on water scarcity as conflicts emerge and are likely to escalate over competing water demands for energy production, municipal use, agricultural irrigation, and ecosystem protection.


Water Evaluation and Planning Model (WEAP). One of the most powerful decision support technologies NCAR brings to water resource planning and management is the WEAP model, developed in collaboration with the Stockholm Environment Institute (SEI). WEAP is a sophisticated, yet user-friendly, tool that couples physical hydrology with relevant water management parameters, set by the user, to create scenarios to explore potential consequences of climate change on water management decisions. 


WEAP is currently used by several thousand water resource managers in the U.S. and in 170 countries around the world.
