Effect of Urbanization on the Water Resources of Warminster Township, Bucks County, Pennsylvania

Description: Purpose: This investigation by the U.S. Geological Survey, in cooperation with the Warminster Municipal Authority, has three purposes: (1) to determine how urbanization has affected ground water and low streamflow in Warminster Township and parts of the surrounding municipalities; (2) to describe the hydrologic system; and (3) to assess the availability of ground water.

Effects of Volcanic Ash on the Benthic Environment of a Mountain Stream, Northern Idaho

Description: Purpose and scope: The purpose of the study was to determine whether a thin layer of volcanic ash measurably affects aquatic environments. Study objectives were to: (1) Determine the amount of ash initially deposited in Big Creek basin and the amount remaining 1 year after the eruption, and (2) describe the impact of ash on water quality and benthic invertebrate communities.

Comparison of the Propane-Area Tracer Method and Predictive Equations for Determination of Stream-Reaeration Coefficients on Two Small Streams in Wisconsin

Description: From abstract: "This study was made to identify the best predictive equations for a stream's reareation-rate coefficient. Reaeration-rate information is needed in dissolved-oxygen modeling work, but an actual tracer measurement is not always possible."

Hydrologic Effects of Proposed Changes in Management Practices, Winnebago Pool, Wisconsin

Description: From abstract: "Various changes in the management practices for the Winnebago pool to protect wetlands adjacent to the pool and to assure adequate streamflow downstream from the pool have been proposed. The effects of three such changes were estimated by using a digital reservoir model to simulate daily stage and discharge."

Hydrologic Effects of Annually Diverting 131,000 Acre-Feet of Water from Dillon Reservoir, Central Colorado

Description: From abstract: because of the increased demands for water in eastern Colorado, principally in the urbanizing Denver metropolitan area, increased diversions of water from Dillon Reservoir are planned. Estimates of end-of-month storage in Dillon Reservoir, assuming the reservoir was in place and 131,000 acre-feet of water were diverted from the reservoir each year, were reconstructed by mass balance for the 1931-77 water years. Based on the analysis, the annual maximum end-of-month drawdown below… more

Geohydrologic Data from the Jemez Mountains and Vicinity, North-Central New Mexico

Description: Abstract: The Jemez Mountains volcanic region, on the west margin of the Rio Grande rift in north-central New Mexico, is the site of studies whose objective is power development using geothermal heat. This report summarizes geohydrologic data obtained to provide background information relative to the geothermal exploration and to investigate the usefulness of hydrology in assessment of the geothermal resource. Eleven tables present chemical, temperature, discharge, and other data for springs, w… more

Nitrification in Four Acidic Streams in Southern New Jersey

Description: Abstract: Chemical and microbiological data from four characteristically acidic streams in southern New Jersey were used to evaluate seven factors related to the proclivity of each stream to nitrify under the influence of secondary sewage effluent. pH, water temperature, and dissolved oxygen were used as indicators of a stream conditions while neutralization of alkalinity, nitrogen species trends, BOD/NOD incubations, and nitrifying bacteria densities served as actual nitrification indicators. … more

Ground-Water Resources of the Alluvial Aquifers in Northeastern Larimer County, Colorado

Description: From introduction: Ground water is a source of municipal, domestic, stock, and irrigation water supply for most of northeastern Larimer County, Colorado. This report presents the results of a study made to determine the quantity, availability, and quality of the ground water. This information should be useful particularly for land-use planning and the utilization and protection of the ground-water resources.

Floods in New York, 1972, with Special Reference to Tropical Storm Agnes

Description: From introduction: Flooding and flood damage in New York during the calendar year 1972 are summarized in this report. The report was prepared at the request of the New York State Department of Transportation under provisions of an agreement between the department and the U.S. Geological Survey for a cooperative, statewide program to investigate the water resources of the State.

Measurement and Prediction of Sediment Yields in Wisconsin Streams

Description: From introduction: This report presents practical and useful sediment-yield information for Wisconsin. Measured and estimated sediment yields are supplemented by information on suspended-sediment concentration and particle size of suspended and bed material for 84 sites in the State. To expand the usefulness of these data, an additional section in the report presents a method to estimate or predict sediment yields in ungaged streams.

Preliminary Digital Model of Ground-Water Flow in the Madison Group, Powder River Basin and Adjacent Areas, Wyoming, Montana, South Dakota, North Dakota, and Nebraska

Description: Abstract: A digital simulation model was used to analyze regional ground-water flow in the Madison Group aquifer in the Powder River Basin and adjacent areas. Most recharge to the aquifer originates in or near the outcrop areas of the Madison in the Bighorn Mountains and Black Hills , and most discharge occurs through springs and wells. Results from the model calculations indicate that the total flow through the aquifer in the modeled areas was approximately 200 cubic feet per second (5.7 cubic… more

Effects of Urbanization on Floods in the Dallas, Texas Metropolitan Area

Description: From abstract: The analyses indicate that in a fully-developed residential area, the flood peaks with be 1.2 to 1.4 times those from an undeveloped area; and the annual direct runoff will be about double that from an undeveloped area. Data were not sufficient to determine the increase in runoff from a highly industrialized area where the effective imperviousness approaches 100 percent.

Salt-Water Movement in the Lower Withlacoochee-Cross-Florida Barge Canal Complex

Description: The intent of the investigation was to determine how salt water from the Gulf moves in the river-canal complex under the influence of various combinations of fresh-water discharge and ocean tide. Information about the extent of inland movement, concentration, frequency of occurrence, and residence times of salt water in the river and canal was sought, particularly during times of farthest upstream movement of the salt water.
