Water supply and demand
The quantities of water resources in an area that are easily available and the amount of water that is needed for all uses.
A new tool to assess groundwater resources in the Mississippi embayment [ More info] Mathematical model of the groundwater system in this area includes 13 types of data and spans multiple aquifers over more than a century. This enables us to assess the quantity of groundwater, where and how it is being used, and how pumping affects it.
Alabama Water Use, 2005 [ More info] Detailed information about how water is used in Alabama by type of use and geographic area.
Assessing Groundwater Availability in the High Plains Aquifer in Parts of Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming [ More info] Explains concepts and methods used to determine the likely future supply of usable water in this major aquifer.
Assessing groundwater availability in the North Atlantic Coastal Plain aquifer system [ More info] Nature, history, and distinctive characteristics of this aquifer system help us to understand the likely distribution of available groundwater.
Biosolids, Animal Manure, and Earthworms: Is There a Connection? [ More info] Research findings and examples of application to real problems--how household contaminants accumulate in and effect the environment
California's Central Valley Groundwater Study: A Powerful New Tool to Assess Water Resources in California's Central Valley [ More info] Modeling effort that integrates a wide variety of geographic, hydrologic, agricultural, climatic, and biological information to help local land managers address resource use issues.
Changes in Water Levels and Storage in the High Plains Aquifer, Predevelopment to 2007 [ More info] Summarizes changes in water levels and drainable water in storage in the High Plains aquifer from predevelopment (before about 1950) to 2007.
Changes in water levels and storage in the High Plains Aquifer, predevelopment to 2009 [ More info] Summarizes graphically the areas where water levels have dropped, and by how much, in this extensive underground water reservoir that covers several states in the mid-continent.
Distribution of high-temperature (>150 °C) geothermal resources in California [ More info] Description and map of geothermal resources in California.
Drought and deluge: Effects of recent climate variability on groundwater levels in eastern Arkansas [ More info] Water levels in wells completed in the Mississippi River Valley alluvial aquifer and the Sparta aquifer in eastern Arkansas respond to variability associated with annual precipitation.
