Abstract: California's Central Valley is one of the world's most productive farmland, but the region faces a serious threat to groundwater sustainability due to population growth and climate change. Recharging ground aquifers is essential to address this challenge, however a major data gap exists in the subsurface. Geophysical sensor data can provide crucial information about the subsurface, but neither the data nor the analytic tools required to derive subsurface information is readily accessible to those working on the recharge problem.

In this talk, I will present our development of a web-application and companion public database for accelerating groundwater recharge in California. Our application uses electrical resistivity data obtained from electromagnetic geophysical surveys, as well as auxiliary data from driller's logs (containing information about sediment/rock) and water level/quality measurements, to create 2D maps of recharge metrics. These maps guide the location of recharge sites. The public resistivity and auxiliary data are compiled into an online database and displayed in a custom web-application. The application provides practitioners facing the recharge problems with the ability to utilize research codes and is flexible to allow updates by researchers to support rapid changes and feedback from partners to meet their specific needs for a recharge site location. Our project showcases a unique combination of open-source tools and open data to help turn research knowledge into actionable insights for practitioners to improve groundwater recharge in California.
