From introduction: This report contains the findings of the first full year of data collected as part of a 3-year study to measure sediment discharges in the East Branch Mahoning Creek during installation of erosion and sedimentation controls by the surface miners.

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.

From abstract: At the Kaiser Aluminum and Chemical Corporation plant, Mulberry, Florida, high-chloride, acidic liquid wastes are injected into a dolomite section at depths below about 4,000 feet below land surface. Sonar caliper logs made in April 1976 revealed a solution chamber that is about 100 feet in height and has a maximum diameter of 23 feet in the injection zone.

From purpose and scope: The purpose of this report is to present and interpret information on water-quality conditions in the Broward County canal system from 1969-74 for use by agencies involved with water management and other interested concerns or individuals.

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-frequency discharge for sites on gaged and ungaged streams in South Carolina. Relationships of flood discharge and frequency to drainage area are presented for the main stem of major streams. A compilation of flood records for gaging stations in South Carolina is presented as supplemental data.
