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...

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...

CoSMoS 1.0: Southern California

CoSMoS was initially developed and tested for the Southern California coast in collaboration with Deltares. CoSMoS has been used to assess coastal vulnerability within Southern California for the ARkStorm scenario, the January 2010 El Niño and Sea-Level Rise scenarios, and the January 2005 Newport Harbor Flood scenario.

Virginia Bankfull Regional Curves Project

Properly developed regional curves for a specific hydro-physiographic province are an invaluable tool for stream restoration design. Development of regional curves specifically for physiographic provinces of Virginia will enhance the ability to develop successful natural channel designs based on climatic, geologic, and hydrologic characteristics of specific regions of the state.

Quality of Shallow Groundwater and Drinking Water in the Mississippi Embayment-Texas Coastal Uplands Aquifer System and the Mississippi River Valley Alluvial Aquifer, South-Central United States, 1994–2004

The Mississippi embayment-Texas coastal uplands aquifer system is an important source of drinking water, providing about 724 million gallons per day to about 8.9 million people in Texas, Louisiana, Mississippi, Arkansas, Missouri, Tennessee, Kentucky, Illinois, and Alabama. The Mississippi River Valley alluvial aquifer ranks third in the Nation for total withdrawals of which more than 98...
