Preliminary hydrologic budget of the sand-and-gravel aquifer under unstressed conditions: with a section on water-quality monitoring, Pensacola, Florida

Henry Trapp Jr.

1978, Water-Resources Investigations Report 77-96

The sand-and-gravel aquifer is the only freshwater aquifer in southern Escambia County, Fla. Problems related to the development of the aquifer include sustained yield, contamination, and saltwater intrusion. A digital model was applied to the sand-and-gravel aquifer in central and southern Escambia County treating the aquifer 's 'main producing zone...

Methods of estimating recharge to the Floridan aquifer in northeast Florida

G. G. Phelps

1978, Water-Resources Investigations Report 77-109

Recharge to the principal artesian aquifer in a six-county area in northeast Florida was calculated using closed contour methods , water budgets, and formulas for computing leakage through confining beds. Each estimate was tested in a computer model of groundwater flow to see which estimate was best. Calculations of flow...

Hydrology of the Nevin Wetland near Madison, Wisconsin

R.P. Novitzki

1978, Water-Resources Investigations Report 78-48

The 120-acre Nevin wetland at the south edge of Madison, Wis., is a discharge area of the local ground-water system. A hydrologic unit composed of drift and the upper part of an underlying sandstone sequence provides ground-water inflow. Ground water enters as springflow and as leakage upward through the organic...

Method of estimating natural recharge to the Edwards Aquifer in the San Antonio area, Texas

Celso Puente

1978, Water-Resources Investigations Report 78-10

The method of estimating annual recharge is based on data collected from a network of stream-gaging stations and on assumptions related to applying the runoff characteristics from gaged areas to ungaged areas. The basic approach is a water-balance equation, in which recharge within a stream basin is the difference between...

This report presents hydrologic, geologic, and water-quality data collected within the Ochlockonee River basin area, in the panhandle of northwest Florida. The data are presented in graphs and tables. Surface-water data include streamflow measurements and analyses of water collected at 58 sites; ground-water data include descriptions of 360 wells and...
