Tutorial data for WMOST Climate Automation Tool

This dataset provides data for a tutorial associated with US EPA 2024 "WMOST Climate Automation Programs (WCAP) Instructions v.1: SWAT Batch Climate Runs, Hydrologic Comparison Assessment Module (HCAM-R) for SWAT, HAWQS". The Watershed Management Optimization Tool (WMOST) is an Excel-based tool designed to aid decision making in integrated water resources management. It is meant to be run for small watersheds (HUC10 to HUC12 scale) and over a range of planning years. WMOST uses baseline runoff and recharge time series for both water and pollutant loadings from models such as the Soil and Water Assessment Tool (SWAT), Hydrological Simulation Program in Fortran (HSPF), and the Stormwater Management Model (SWMM), which are in turn modified to reflect various management practices. WMOST is linked behind the scenes with EPA’s SWMM model to simulate the effects of stormwater best management practices (BMPs) on hydrology and loads. While simulation of a few agricultural conservation practices are also coded within WMOST itself, the user can simulate many more agricultural practices, e.g., no-till, contour plowing, terracing, grassed swales, etc., using a SWAT model and then incorporating the output time series into WMOST as “managed sets”. WMOST sets up optimization problems in files described in the AMPL language which the user uploads to the online NEOS server where least cost optimizations take place. The WMOST Climate Automation Programs (WCAP) are a suite of WMOST version 3.1 add-ons that automate the creation and processing of runoff and recharge time series that reflect varying climate change scenarios. The suite of WCAP programs include the SWAT batch climate runs code, Hydro-Climate Automation Module (HCAM)0F1, Hydro-Climate Automation Module R Version (HCAM-R), and the Climate Automation Module wrapper program (CAM-WRAP). Together with the existing capabilities of WMOST, these tools can be used with ScenCompare1F2, the WMOST Climate Scenario Viewer and Comparison Post Processor (EPA, 2018c) to compare optimization results across a range of climate change scenarios. These instructions document the use of three WCAP programs: SWAT batch climate runs code, HCAM-R, and CAM-WRAP, including software requirements, data requirements, and recommended folder structure3. A detailed, step-by-step case study is included in Appendix D to demonstrate the use of these programs.
