Results of ground-surface monitoring and borehole water table measurements document subsidence of the land surface correlative with changes in the ground water.
We applied a groundwater model to simulate effects of groundwater pumping and artificial recharge on surface water in this area. Results show effects of pumping or recharge on streamflow.
Planned analysis of the sensitivity of groundwater levels to changes in air temperature and precipitation. Changes in groundwater recharge and discharge also will be correlated with other hydrologic indicators.
Short descriptions of the research and monitoring activities we are carrying out to assist state, local, and Federal agencies dealing with water resource issues in the southern part of the state.
Explains 16 distinct types of scientific information that are needed to understand climate change, including the specific parameters measured, why they are needed, who measures them, and the type and amount of information that are not yet available.
Maps of three ground-water monitoring networks that group related wells and data from active well networks, and provide basic statistics about the water-level data collected by USGS.
