Hydrogeologic data for the lower Connecticut River basin, Connecticut

This report contains geologic, ground-water, and miscellaneous data on the quality of surface water collected for a water-resources inventory of the lower Connecticut River basin, Connecticut. The study was made by the U.S. Geological Survey in fiscal cooperation with the Connecticut Department of Environmental Protection. A companion report (Connecticut Water Resources Bulletin No. 31, in preparation) interprets the factual information presented here or otherwise collected for the study.

Hydrology of the surficial aquifer in the Floyd River Basin, Iowa

The Floyd River basin was studied to provide water-resources Information for a typical surficial aquifer in northwest Iowa. Data collection included test drilling, water-level measurements, and chemical analyses of surface and ground water. The Floyd River basin drains 961 square miles of highly dissected to gently rolling topography. Major streams generally are flanked by flood plains underlain by uncemented sand and-gravel deposits. Most of the basin is directly underlain by glacial drift of Pleistocene age which is In turn underlain by rocks of Cretaceous age. Sand-and-gravel deposits underlying the major flood plains and in buried bedrock channels within the drift comprise the surficial aquifer. The surficial aquifer ranges from 10 to 40 feet In thickness and averages about 20 feet thick. Both unconfined and confined conditions occur in the aquifer and water levels range from 2 to 55 feet below land surface. An aquifer test conducted in the surficial aquifer where it is about 25 feet thick and is confined by an overlying low permeability bed Indicated an average hydraulic conductivity of 383 feet per day and a storage coefficient of 0.0001. The well was pumped at 650 gallons per minute for 43 hours. An observation well about 70 feet from the pumping well had a maximum drawdown of about 10 feet.

Bibliography of U.S. Geological Survey water-resources reports for Utah

This bibliography contains a complete listing to December 31, 1986, of reports relating to the water resources of Utah prepared by personnel of the U.S. Geological Survey. Discussions of the related subjects of geology, hydrology, and chemical quality of the water are included in many of the reports. The reports were, for the most part, prepared by personnel assigned to the Water Resources Division, Utah District, in cooperation with State, other Federal, and local agencies. A few reports were prepared under contract with the Geological Survey or in cooperation with the geological Survey. A few were compiled under direct funds to the U.S. Geological Survey.

NHDPlus as a geospatial framework for SPARROW modeling

Successful water-resource management requires thorough knowledge and understanding of the relations among water-quality contaminate sources and the factors that affect the transport throughout a hydrologic system. Surface-water modeling is a valuable tool that can be applied to help advance and achieve the understanding of these dynamic relations. Spatially Referenced Regressions on Watershed Attributes (SPARROW) is one such model that uses nonlinear statistical methods to define conceptual and spatial relations among quantities of contaminant sources, monitored contaminant load, aquatic transport processes. NHDPlus Version 2 (V2) is a digital representation of a hydrologic network of streams and associated catchments. The dataset provides the fundamental spatial framework for SPARROW modeling.
