Watershed Management Optimization Support Tool (WMOST) v1: Theoretical Documentation
The Watershed Management Optimization Support Tool (WMOST) is a screening model that is spatially lumped with options for a daily or monthly time step. It is specifically focused on modeling the effect of management decisions on the watershed. The model considers water flows and does not consider water quality. The optimization of management options is solved using linear programming. The tool is intended to be used as a screening tool as part of an integrated watershed management process such as that described in EPA's watershed planning handbook.
The objective of WMOST is to serve as a public-domain, efficient, and user-friendly tool for local water resources managers and planners to screen a wide-range of potential water resources management options across their watershed or jurisdiction for cost-effectiveness as well as environmental and economic sustainability.
Examples of options that could be evaluated with the tool potentially include projects related to stormwater, water supply, wastewater and water-related resources such as low-impact development (LID) and land conservation. The tool is intended to aid in evaluating the environmental and economic costs, benefits, trade-offs and cobenefits of various management options. In addition, the tool is intended to facilitate the evaluation of LID and green infrastructure as alternative or complementary management options in projects proposed for State Revolving Funds (SRF).
The target user group for WMOST consists of local water resources managers, including municipal water works superintendents and their consultants.
