Impact/Purpose:
Water resource management under future climate, land-use, and population change can be very challenging with shifts in the frequency of extreme events (both flooding and drought). Robust decision-making (RDM) tools are required to inform solutions in cases of deep uncertainty. EPA ORD has been creating a suite of tools to work in conjunction with WMOST v3.1 to test the robustness of current optimal (least-cost) solutions to meet water quantity and quality goals under future climate change scenarios. The newest version of WMOST, version 3.1, is designed to work in conjunction with the Hydrologic Comparison Assessment Module (HCAM) to analyze multiple WMOST runs for different climate scenarios.
Description:
The Watershed Management Optimization Support Tool (WMOST) is an EPA application that allows users to find the most cost-effective solutions to meet water quality and quantity goals through integrated water management, considering solutions in stormwater management (green and gray infrastructure), wastewater, drinking water, and land conservation. The new version 3.1 was designed to work in conjunction with the Hydrological Comparison Assessment Module (HCAM) utility, which prepares multiple WMOST runs for different climate scenarios by running EPA's Stormwater Management Model (SWMM) to estimate ruban runoff and loading reductions associated with stormwater control practices. Users can reference the combined instructions for WMOSTv3.1 + HCAM, as well as earlier user guides describing the fundamentals of WMOST v3.0. Both 32-bit and 64-bit versions of WMOST v3.1 are provided.
