WEAP

Water Evaluation and Planning

The Water Evaluation and Planning (WEAP) system is a water resources watershed planning model. WEAP evaluates water uses, facilitates stakeholder involvement, and evaluates management scenarios. Modeled processes include rainfall-runoff dynamics, water quality kinetics, groundwater flow, vulnerability assessments, ecosystem impacts, and crop and vegetation interactions.

Model Information
For more information about this model, go to www.weap21.org
Spatial Resolution
Model is GIS based. The spatial resolution is variable, ranging from the small neighborhood to regional watershed scale. Infrastructure systems are modeled at the distribution system or county level scale and hydrologic systems are modeled at the catchment scale.
Temporal Resolution
Output is recorded at a monthly or yearly interval. Time step can vary on the order of days to years.
Outputs
Outputs include hydrologic routing, water quality , and energy demands among others.
