Integrated Hydrology for an Urban Watershed
Abstract
The Anacostia River Watershed is a small urban catchment that covers 460 km2, extends 14 km long, and hosts over one million people. The head waters originate in Maryland (Montgomery and Prince George Counties) and flow south through the nation's capital, eventually discharging into the Potomac River. While this ecosystem has been a critical resource for the United States, it is currently contaminated with fecal coliform, heavy metals, trash, and algae blooms. To better understand the natural flow patterns and improve water quality of the catchment, this study implements HydroGeoSphere (a fully-integrated 3D subsurface/surface water flow model) over the entire domain. The simulation boundaries are the watershed's hydrological divides, thus removing the need for interflow between basins. Furthermore, the model implements the high resolution USGS National Map 3DEP elevation model, USDA Web Soil Survey, and USGS Global Land Cover data.
