Hydrologic Modeling
Hydrologic Modeling
The USGS has been a leader in the development of hydrologic and geochemical simulation models since the 1960's. USGS models are widely used to predict responses of hydrologic systems to changing stresses, such as increases in precipitation or ground-water pumping rates, as well as to predict the fate and movement of solutes and contaminants in water.

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...
Assessing Geomorphic Change in Support of Science-Based Restoration, Trinity River, CA
Historic landuse, dam construction, water storage and flow diversion within the Trinity River watershed resulted in downstream geomorphic changes that simplified the river planform and lead to dramatic losses of salmonid habitat and significant population declines. The Trinity River Restoration Program (TRRP) requested the USGS complete an assessment of geomorphic change that could be used to...
