Groundwater and … The Central Valley Hydrologic Model (CVHM) simultaneously accounts for changing water supply and demand across the landscape, and simulates surface water and groundwater flow across the entire Central Valley. The GAMA-PBP is a cooperative program between the California State Water Resources Control Board and the U.S. Geological Survey. An understanding of how water quality varies spatially, temporally, and with depth are critical aspects to ensuring long-term sustainable use of these resources. The complex hydrologic system of the Central Valley is simulated by using the USGS hydrologic model, MODFLOW. The USGS Earthquake Hazards Program is part of the National Earthquake Hazards Reduction Program (NEHRP), established by Congress in 1977, and the USGS Advanced National Seismic System (ANSS) was established by Congress as a NEHRP facility. We created the first Central Valley-wide time series maps of MSS plant distributions and productivity. An understanding of how water quality varies spatially, temporally, and with depth are critical aspects to ensuring long-term sustainable use of these resources. The Central Valley's population is expected to increase to 6 million by 2020. This agriculture relies heavily on surface-water diversions and groundwater pumpage to meet irrigation water demand. The ability to dynamically simulate the integrated supply-and-demand components of irrigated agricultural is needed to thoroughly understand the interrelation between surface water and groundwater flow in areas where the water-use by vegetation is an important component of the water budget. The entire Sacramento and San Joaquin valleys were inundated. The Central Valley is virtually one large sediment-filled valley between the Coast Ranges and the Sierra Nevada.

Fram2, Kenneth Belitz3, Karen R. Burow2, and Matthew K. Landon3 Abstract Uranium (U) concentrations in groundwater in several parts of the eastern San Joaquin Valley, California, have exceeded federal and state drinking water standards during the last 20 years. Aquifer-system compaction has been monitored at selected locations for various periods with borehole extensometers by different agencies, including the USGS, DWR, SLDMWA, and CCID, and by Luhdorff and Scalmanini Consulting Engineers. Therefore, it is likely that groundwater levels will decline in the future. The CVHM helps to address water competition issues such as: A Geographic Information System (GIS) was used to compile, manage, store, and analyze the large quantities of data in the geospatial database needed to run the model, and to understand and visualize the data output.
