Research Project: Research Support for Watershed and Basin Hydrology and Water Qualty in the Arid and Semi-arid Southwest, USA

Location: Southwest Watershed Research Center

Project Number: 2022-13610-012-16-S
Project Type: Non-Assistance Cooperative Agreement

Start Date: Jan 15, 2017
End Date: Jul 30, 2019

To evaluate the utility of innovative, distributed, low impact development (LID) infrastructure and best management practices (BMPs) for wet weather capture and drinking water aquifer recharge in the arid and semi-arid southwestern USA.

The approach is described as follows. 1) Conduct a site visit to Fort Irwin to tour the base and consult with Fort staff; 2) Acquire the most current watershed characterization data; 3) Use AGWA to construct a KINEROS2 watershed model representation of the area draining into the Four Plex recreation area; 4) Conduct simulations using idealized precipitation inputs (uniform in time and space) of sufficient duration to drive the modeled runoff to equilibrium; 5) Develop an internal EPAARS technical report describing data sources, model construction, and initial model testing.
