Ground water information pages [More info]
Lead page to connect to ground water information on the Nation's ground water resources and ground water activities of the USGS. Includes links to ground-water data, news reports, publications, field techniques, models, programs, and issues.
Ground-water flow and other computer simulations for Utah [More info]
Identifies computer models in USGS publications developed to study ground water for many areas of Utah.
PDF Hawaii StreamStats; a web application for defining drainage-basin characteristics and estimating peak-streamflow statistics [More info]
Interactive maps providing selected analyses on areas you choose
Hazards, disasters, and the National Map [More info]
Fact sheet describing the value of The National Map designed as a network of digital databases that will provide a consistent national geographic data framework in responding to natural hazards and human-induced disasters.
PDF Historical changes in annual peak flows in Maine and implications for flood-frequency analyses [More info]
Annual peak flows have increased at most rivers in Maine during the last century. What effect does this have on computed peak flows, such as the 100-year flows, that are used for designing bridges and other structures?
Housing arrangement and location determine the likelihood of housing loss due to wildfire [More info]
Using a geographic dataset of structures, with more than 5500 structures that were destroyed or damaged by wildfire since 2001, we identified the main contributors to property loss in two extensive, fire-prone regions in southern California.
Hydraulics Laboratory [More info]
Includes an indoor hydraulics laboratory available for rent. Links to meter calibrations, current meter performance, and modeling activities.
PDF Impacts and predictions of coastal change during hurricanes [More info]
Shows how observations and modeling can help anticipate practical problems in coastal areas when hurricanes arrive. Focuses primarily on areas where people have built houses and roads that may be destroyed during storms.
PDF Impacts of Low-Flow and Stream-Temperature Changes on Endangered Atlantic Salmon - Current Research [More info]
Recent physical changes over time, including trends toward earlier snowmelt runoff, decreasing river ice, and increasing spring water temperatures, may affect salmon populations; we want to know how important these effects are.
PDF Integrated Science: Florida Manatees and Everglades Hydrology [More info]
Description of research and monitoring work proposed for 2008 to combine hydrologic models with manatee distribution and movement models near and within Everglades National Park.
