The San Bernardino Valley Water Conservation District, in collaboration with California State University, Sacramento, received a $826,742 Project Grant from the U.S. Department of the Interior Bureau of Reclamation's Applied Science Grants program (CFDA 15.557). The grant funding will be used to enhance the existing Integrated Santa Ana River Model, a combined groundwater and surface water model that is a foundational tool for water management in the Upper Santa Ana River Watershed and San Bernardino Basin. Key enhancements include extending the model calibration period with recharge data from 1912-2023, incorporating updated designs for proposed new recharge facilities and modifications to existing facilities, and evaluating climate change scenarios using the most recent predictions. The updated model will quantify and show groundwater recharge trends over the last century, improve current and future forecasting capabilities, inform accurate cost-benefit analyses for proposed projects, and optimize facility operations. This project is supported by the San Bernardino Valley Conservation Trust, San Bernardino Valley Municipal Water District, and the City of San Bernardino Municipal Water Department.

The SAN bernardino valley water conservation district, in collaboration with california state university, sacramento, will make several enhancements to the existing integrated santa ANA river model, a combined groundwater and surface water model that is a foundational tool for water management in the upper santa ANA river watershed, and the SAN bernardino basin in particular. Enhancements will extend the model calibration period with recharge data available from 1912-2023, incorporate updated designs for proposed new recharge facilities and modifications to existing recharge facilities into the model, and evaluate with climate change scenarios using the most recent predictions. The updated model will quantify and show the groundwater recharge trends over the last century, improve current and future forecasting capabilities, inform accurate cost benefit analyses for proposed projects, and optimize facility operations. This project is supported by the SAN bernardino valley conservation trust, SAN bernardino valley municipal water district, and the city of SAN bernardino municipal water department.
