Hydrogeology of the Sarasota-Port Charlotte area, Florida
R. M. Wolansky
1983, Water-Resources Investigations Report 82-4089
The surficial and intermediate aquifers are the major source of public water supplies in the Sarasota-Port Charlotte, Florida, area because of the relatively poor quality of Floridan aquifer water. The hydrogeologic framework consists of the surficial aquifer, intermediate aquifers (Tamiami-upper Hawthorn and lower Hawthorn-upper Tampa aquifers) and confining beds, Floridan...

1983, Water-Resources Investigations Report 83-4062
Water-quality data were collected from 92 wells in the western Snake River basin, Swan Falls to Glenns Ferry, Idaho. Current data were compiled with pre-1980 data from 116 wells to define water-quality conditions in major aquifers. Factors affecting water quality are composition of aquifer materials, water temperature, and source of...

Hydraulic considerations in sampling the unsaturated zone with inclined gravity lysimeters
E. T. Oaksford
1983, Water-Resources Investigations Report 83-4005
Inclined gravity lysimeters as deep as 5.39 meters below land surface designed for sampling soil water in coarse sand under continuous ponding conditions, were shown to be capable of collecting 10 liters per hour at an infiltration rate of 0.5 meter per hour. This represents a capture efficiency of approximately...
Mean annual runoff and peak flow estimates based on channel geometry of streams in northeastern and western Montana
Charles Parrett, R. J. Omang, J. A. Hull
1983, Water-Resources Investigations Report 83-4046
Equations for estimating mean annual runoff and peak discharge from measurements of channel geometry were developed for western and northeastern Montana. The study area was divided into two regions for the mean annual runoff analysis, and separate multiple-regression equations were developed for each region. The active-channel width was determined to...
