A Stormwater Management Model for the West Branch Brandwyne Creek, Chester County, Pennsylvania

Description: From introduction: This report describes rainfall-runoff modeling for three subbasins of the West Branch Brandywine Creek basin. Effects of increased runoff from continued urbanization of the basin and of proposed flood-control structures for both the present and projected population are evaluated for the West Branch Brandwyne Creek at Coatesville and Modena and for Sucker Run at State Route 82.

Techniques for Estimating Magnitude and Frequency of Floods in South Carolina

Description: Information is presented for estimating the magnitude and frequency of floods on streams in South Carolina. Flood-frequency characteristics for 151 gaging stations were related to basin characteristics by multiple regression techniques for each of four physiographic provinces. Equations were derived to estimate flood magnitudes at recurrence intervals ranging from 2 to 100 years on streams with drainage areas greater than 1.0 square mile. Examples demonstrate the procedure for computing flood-f… more

Chemical, Physical, and Radiological Quality of Selected Public Water Supplies in Florida, January-May 1979

Description: Abstract: Most public water supplies sampled in Florida meet the National Interim Primary and Proposed Secondary Drinking Water Regulations. This conclusion is based on a water quality reconnaissance of 131 raw and treated public supplies throughout the State during the period January through May 1979. In a few public supplies, primary drinking water regulation maximum contaminant levels were exceeded for mercury, turbidity, and gross alpha particle activity. Secondary drinking water regulation… more
