The goal of the LA's Water Resource Future series is to bring together researchers, water resource managers, and other stakeholders to investigate the question: How much stormwater can Los Angeles County capture and store as groundwater by 2050 and beyond, given climate change, water quality concerns, ecosystem concerns, and economic and policy constraints? This discussion will inform the implementation of the UCLA Sustainable LA Grand Challenge Work Plan by identifying stakeholder information needs, research capabilities and gaps, and opportunities for collaboration.
This workshop is the second in a two-part series. The first, Understanding Local Stormwater Capture Potential, explored recent stormwater capture planning efforts and the modeling tools used therein; how to achieve integrated climate, surface hydrology, and groundwater modeling; ecosystem considerations in stormwater capture; and policy barriers to increased capture and potential solutions.
We are now undertaking a research effort to couple existing stormwater capture and groundwater models to get a better grasp of the quantities of captured stormwater that infiltrates to groundwater for projects that don’t go into a spreading ground through a pipe.
This second workshop will focus on current and future groundwater basin conditions, management, and rights in the groundwater basins serving Los Angeles County. The aims are to better understand:
