Summary

The Los Angeles Coastal Plain (LACP) covers about 580 square miles and is the largest coastal plain of semiarid southern California. The LACP is heavily developed with mostly residential, commercial, and industrial land uses that rely heavily on groundwater for water supply. In 2010, the LACP was home to about 14 percent of California’s population and is also a major commercial and industrial hub. There has been a heavy reliance on groundwater from the LACP for many years. Managed aquifer recharge from the spreading grounds and barrier wells is now a substantial component of the LACP’s groundwater supply. The U.S. Geological Survey (USGS) conducted a study in cooperation with the Water Replenishment District of Southern California [...]

Purpose

The Los Angeles Coastal Plain Groundwater Model in MODFLOW-6 (LACPGM-6) was developed as a tool to understand the groundwater flow system in the Los Angeles Coastal Plain (LACP). Specifically, the Los Angeles Coastal Plain Groundwater-flow Model (LACPGM-USG) (https://doi.org/10.3133/sir20215088) was updated to extend the model in time, fix inconsistencies and errors in the original model, incorporate new or revised data, and to facilitate a host of follow-up studies on the basin that will leverage capabilities of the MODFLOW-6 software (https://doi.org/10.5066/F76Q1VQV) including three-dimensional density dependent flow and transport and integration with other modeling software. The methods and interpretations of the model included in this data release are based on those documented in the U.S. Geological Survey Scientific Investigations Report 2021-5088 (https://doi.org/10.3133/sir20215088).
