San Bernardino Optimal Basin Management

The San Bernardino area of southern California has complex water-management issues. As an aid to local water managers, this report provides an integrated analysis of the surface-water and ground-water systems, documents ground-water flow and constrained optimization models, and provides seven examples using the models to better understand and manage water resources of the area. As an aid to...

Central Valley Hydrologic Model (CVHM)

In an effort to aid water managers in understanding how water moves through the aquifer system, predicting water-supply scenarios, and addressing issues related to water competition, the USGS developed a new hydrologic modeling tool, the Central Valley Hydrologic Model (CVHM). The CVHM is an extensive, detailed three-dimensional (3D) computer model of the hydrologic system of the Central...
