Environmental Flow Research in the Tennessee River Basin

The objective of this project is to improve understanding of how alteration of streamflow characteristics affects the ecological health of rivers and streams in Tennessee. Initial efforts are aimed at identifying critical streamflow characteristics and providing a set of statistical tools and analytical approaches for the prediction of these characteristics. Application of these tools will...

U.S. Geological Survey Flood Inundation Mapping Science

Static flood-inundation map libraries consist of maps that have been created in advance of a flood that are ready to be served through the Internet. Each library consists of a set of flood extent and depth maps developed for predetermined stream stage intervals (for example, a map for each one foot of stage). A user can view real-time or forecast stage data from a USGS streamgage or National...

USGS StreamStats

StreamStats is a Web-based tool that provides streamflow statistics, drainage-basin characteristics, and other information for USGS streamgaging stations and for user-selected ungaged sites on streams. When users select the location of a streamgaging station, StreamStats provides previously published information from a database. When users select a site on an ungaged stream, StreamStats will...

Predicting ecological flow regime at ungaged sites: A comparison of methods

Nineteen ecologically relevant streamflow characteristics were estimated using published rainfall–runoff and regional regression models for six sites with observed daily streamflow records in Kentucky. The regional regression model produced median estimates closer to the observed median for all but two characteristics. The variability of predictions from both models was generally less than the...

Watershed Restoration & Protection Studies (319 Monitoring) - Mississippi

The USGS-MWSC partners with various federal, state and local cooperating agencies to implement Monitoring Plans for watershed restoration or protection projects. The purpose of monitoring is to measure change in water quality throughout the duration of watershed specific restoration efforts targeted to remediate specific pollutants of concern. The goal is to document, using defensible...

Terrestrial Light Detection and Ranging (T-LiDAR) Technology

T-LiDAR technology utilizes reflected laser pulses sent from a tripod-mounted scanning instrument to determine distances to targets of interest. The resulting dataset is a 3 dimensional model or "point cloud" of millions of XYZ data points, spaced only a few millimeters apart. This highly detailed dataset is used by USGS scientists to create topographic models, make detailed measurements, and...

Water Resources of Louisiana’s Parishes

The USGS is summarizing basic information on water resources for each parish in Louisiana and presenting the information in fact-sheet format. Information presented includes groundwater and surface-water availability, quality, development, use, and trends. These brief summaries of water resources will provide parish officials, local officials and concerned citizens with information needed to...

Historical Preservation of Toomer's Oaks in Auburn, AL

The live oaks framing Toomer's Corner in Auburn, Alabama were planted about 1880 and have served as a focal point for Auburn celebrations in recent decades. The trees recently received a powerful dose of an herbicide known as Spike 80DF. In an effort to save the trees, a task force made up of university horticulturists, landscapers, agronomists, engineers, chemists and others has undertaken a...
