San Diego Hydrogeology

Welcome to the United States Geological Survey (USGS) San Diego Hydrogeology project website, which provides geologic and hydrologic information for the transboundary San Diego–Tijuana area, USA and Mexico. This website provides background information about the project; a variety of news items; a large amount of data, in particular for USGS multiple-depth, monitoring-well sites; geologic and hydrologic models; and additional resources including photos, illustrations, and references. Last updated: April 2016

Some additional data may be available from the USGS database National Water Information System (NWIS).

Water-Quality Model

Water-quality models include both lumped and transport models. The lumped models assume all chemical constituents are lumped together, and often are used to identify equilibrium conditions. The transport models assume that water is transported through a medium, like an aquifer, and chemical changes occur along that flow path. Transport models can be used to test the reasonableness of a geologic framework or groundwater flow model.
