Abstract
Hydrological GIS preprocessing tools are used to spatially relate different datasets for producing topologically connected watersheds and deriving attributes for model parameterization. Obtaining such information requires disparate data-sources from various websites with lengthy processing requirements. This research describes the development of HMS-PrePro, an open-source GIS preprocessing tool that was developed for the U.S. Army Corps of Engineers' (USACE) Hydrologic Engineering Center's Hydraulic Modeling System (HEC-HMS) software. HMS-PrePro provides data as a service by connecting to Esri's Living Atlas web service and extracting authoritative hydrological datasets for any watershed of interest in the contiguous United States. The datasets are saved to a local geodatabase, and spatial operations are executed to automatically delineate the watershed, derive topological connections, and estimate several common hydrologic parameters. An output basin text file is produced in HEC-HMS format for rapid model initialization.
