Depth in a well or aquifer at which groundwater occurs.
Land subsidence and aquifer-system compaction in the Tucson Active Management Area, south-central Arizona, 1987-2005 [ More info] Results of ground-surface monitoring and borehole water table measurements document subsidence of the land surface correlative with changes in the ground water.
Possible effects of groundwater pumping on surface water in the Verde Valley, Arizona [ More info] 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.
Quantifying effects of climate change on the snowmelt-dominated groundwater resources of northern New England [ More info] 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.
Science to support the understanding of south Texas surface-water and groundwater resources in a changing landscape [ More info] 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.
Terrestrial essential climate variables (ECVs) at a glance [ More info] 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.
USGS Ground-Water Networks [ More info] 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.
Wyoming groundwater-quality monitoring network [ More info] Shows high-priority areas where groundwater will be monitored, outlines the methods of collection and analysis that will be used.
