Simulation of flood hydrographs for Georgia streams
Flood hydrographs are needed for the design of many highway drainage structures and embankments. A method for simulating these flood hydrographs at ungaged sites in Georgia is presented in this report.The O'Donnell method was used to compute unit hydrographs and lagtimes for 355 floods at 80 gaging stations. An average unit hydrograph and an average lagtime were computed for each station. These av

Chemical effects of highway runoff on the surficial aquifer, Broward County, Florida
In many areas of Broward County, swales are commonly designed to accept stormwater runoff from highways. Two sites adjacent to heavily traveled highways were studied to determine if stormwater percolating through unsaturated sand underlying the swales may affect the quality of water in the Biscayne aquifer. Concentrations of selected chemicals common in highway runoff were measured in swale stormw

Discharge ratings for control gates at Mississippi River Lock and Dam 22, Saverton, Missouri
The water level of the navigation pools on the Mississippi River are maintained by the operation of tainted and roller gates at the locks and dams. Discharge ratings for the gates on Lock and Dam 22, at Saverton, Missouri, were developed from current-meter discharge measurements made in the forebays of the gate structures. Methodology is given to accurately compute the gate openings of the tainter

Discharge ratings for control gates at Mississippi River Lock and Dam 13, Fulton, Illinois
The water level of the navigation pools on the Mississippi River are maintained by the operation of tainter and roller gates at the locks and dams. Discharge ratings for the gates on Lock and Dam 13, at Fullerton, Illinois, were developed from current-meter discharge measurements made in the forebays of the gate structures. Methodology is given to accurately compute the gate openings of the tainte

Tests for injecting, storing, and recovering freshwater in a saline artesian aquifer, Lee County, Florida
An investigation was made of the suitability of a saline, artesian limestone aquifer for the injection, storage, and recovery of freshwater from the Caloosahatchee River. The tests were conducted on a well tapping a leaky artesian system that has a transmissivity of 800 square feet per day, a storage of 1 x 10-4, and a leakance of 0.01 per day. The specific capacity of the injection well was incre

Hydrogeologic conditions and saline-water intrusion, Cape Coral, Florida, 1978-81
The upper limestone unit of the intermediate aquifer system, locally called the upper Hawthorn aquifer, is the principal source of freshwater for Cape Coral, Florida. The aquifer has been contaminated with saline water by downward intrusion from the surficial aquifer system and by upward intrusion from the Floridan aquifer system. Much of the intrusion has occurred through open wellbores where ste

Hydraulic characteristics of Upper Cretaceous and Lower Tertiary clastic aquifers: Eastern Alabama, Georgia, and western South Carolina
Transmissivity and storativity data for the clastic sediments of the northern Coastal Plain of eastern Alabama, Georgia, and western South Carolina were compiled and evaluated. Transmissivity values ranged from less than 100 to about 35,000 ft sq/day; storativity ranged from about 0.00002 to 0.0002. Data for lower Tertiary sediments represented by the Clayton and Tallahatta Formations and equivale

Low-flow profiles of the upper Ocmulgee and Flint rivers in Georgia
This report provides low-flow information for use in evaluating the capacity of streams to supply withdrawals or to accept waste loads from potential new industries without exceeding the limits of State water-quality standards. The report is the first phase of a study of all stream basins north of the Fall Line in Georgia. It covers the Piedmont part if the Ocmulgee and Flint River basins. The low

Planning report for the Edwards-Trinity Regional Aquifer-System analysis in central Texas, southeast Oklahoma, and southwest Arkansas
The Edwards-Trinity regional aquifer system supplies more than 0.78 million acre-feet per year (700 million gallons per day) of water for central Texas and small adjacent parts of southeast Oklahoma and southwest Arkansas. The system consists of three major aquifers and at least three minor aquifers in predominantly Cretaceous rocks, which together have an areal extent of about 80,000 square miles

Surficial aquifer system in eastern Lee County, Florida
The surficial aquifer system in eastern Lee County consists of an upper water bearing unit, which is generally unconfined, and a lower water bearing unit, which is confined and is the major source tapped by most wells. The top of the lower unit, which is of primary interest in this report, ranges in depth from 40 to 60 ft below land surface in the east-central part of the county to more than 120 f
