Summary

The U.S. Geological Survey (USGS), in cooperation with the Water Replenishment District of Southern California, developed a regional groundwater model of the Los Angeles Coastal Plain (LACP) incorporating new data, analyses, and modeling tools to better understand the hydrogeology of the groundwater basins. The LACP covers about 580 square miles and is the largest coastal plain of semiarid southern California. This aquifer is heavily developed with mostly residential, commercial, and industrial use and relies heavily on groundwater for its water supply. There has been a heavy reliance on groundwater from the LACP for many years. The need to replenish the groundwater basins within the LACP was recognized as far back as the 1930s, when [...]

Purpose

This groundwater model was developed as a tool to further understanding of the groundwater flow system in the Los Angeles Coastal Plain (LACP) and be used to forecast groundwater levels. The Los Angeles Coastal Plain Groundwater model is used to simulate past groundwater conditions and estimate water-budget components and to approximate future groundwater conditions under different scenarios. The development of the model input and output files included in this data release are documented in the U.S. Geological Survey Scientific Investigations Report 2021-5088 (https://doi.org/10.3133/sir20215088).
