Research Project: Innovative Infrastructure for Stormwater Capture and Aquifer Recharge in the Arid and Semi-arid Southwest, USA

Location: Southwest Watershed Research Center

Project Number: 2022-13610-012-14-I
Project Type: Interagency Reimbursable Agreement

Start Date: Oct 1, 2016
End Date: Sep 30, 2019

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

Approach:
1) Conduct a site visit to Ft. Irwin to tour the base and consult with Fort staff; 2) Acquire 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 EPA-ARS technical report describing data sources, model construction, and initial model testing.
