Saline-water intrusion related to well construction in Lee County, Florida Saline-water intrusion related to well construction in Lee County, Florida

Ground water is the principle source of water supply in Lee County, Florida where an estimated 30,000 wells have been drilled since 1990. These wells ranges in depth from about 10 to 1,240 feet and tap the water table aquifer or one or more of the artesian water-bearing units or zones in the Tamiami Formation, the upper part of the Hawthorn Formation, the lower part of the Hawthorn...

Geohydrology of Muscatine Island, Muscatine County, Iowa Geohydrology of Muscatine Island, Muscatine County, Iowa

Muscatine Island is a wide segment of the west bank of the Mississippi River flood plain that covers about 50 square miles in Muscatine and Louisa Counties; the project area encompasses the 30 square miles in Muscatine County. The flood plain is underlain by thick, permeable alluvial deposits that comprise a water-table aquifer that is developed extensively for water supplies in the area...

Selected water-level records for western Oklahoma, 1975-1976 Selected water-level records for western Oklahoma, 1975-1976

A systematic program to collect water-level records in Oklahoma began in 1937. The objectives of this program are (1) to provide long-term records of water-level fluctuations in representative wells, (2) to facilitate the prediction of water-level trends and indicate future availability of ground-water supplies, and (3) to provide information for use in basic research. Water-level data...

Stratigraphic and hydrogeologic framework of part of the coastal plain of Texas Stratigraphic and hydrogeologic framework of part of the coastal plain of Texas

The subsurface delineation of hydrogeologic units of Miocene and younger age and stratigraphic units of Paleocene to Holocene age establishes and interrelationship of these units statewide across much of the Coastal Plain of Texas. The 11 dip sections and 1 strike section, which extend from the land surface to 7 ,600 feet below sea level, provide continuity of correlation from the...

Techniques for Estimating Flood-Depth Frequency Relations on Natural Streams in Georgia Techniques for Estimating Flood-Depth Frequency Relations on Natural Streams in Georgia

Regional relations are defined for estimating the depth of floods having recurrence intervals of 10, 50, and 100 years on streams with natural flow in Georgia. Multiple-regression analysis of station data is used to define the relations between flood depths and frequency for streams draining from 1 to 1,000 square miles, and for 10 climatological and physical basin characteristics. The...

Artificial recharge for subsidence abatement at the NASA-Johnson Space Center, Phase I Artificial recharge for subsidence abatement at the NASA-Johnson Space Center, Phase I

Regional decline of aquifer head due to ground-water withdrawal in the Houston area has caused extensive land-surface subsidence. The NASA-Johnson Space Center (NASA-JSC) in southeastern Harris County, Texas, was about 13 to 19 feet above mean sea level in 1974 and sinking at a rate of more than 0.2 foot per year. NASA-JSC officials, concerned about the hurricane flooding hazard...
