Evaluation of the cost effectiveness of the 1983 stream-gaging program in Kansas
K.D. Medina, C.O. Geiger
1984, Water-Resources Investigations Report 84-4107
The results of an evaluation of the cost effectiveness of the 1983 stream-gaging program in Kansas are documented. Data uses and funding sources were identified for the 140 complete record streamflow-gaging stations operated in Kansas during 1983 with a budget of $793,780. As a result of the evaluation of the...
Hydrogeology of well-field areas near Tampa, Florida, phase 2 — Development and documentation of a quasi-three-dimensional finite-difference model for simulation of steady-state ground-water flow
C. B. Hutchinson
1984, Water-Resources Investigations Report 84-4002
This report describes a quasi-three-dimensional finite-difference model for simulation of steady-state ground-water flow in the Floridan aquifer over a 932-square-mile area that contains 10 municipal well fields. The over-lying surficial aquifer contains a water table and is coupled to the Floridan aquifer by leakage term that represents flow through a...
Enhanced job control language procedures for the SIMSYS2D two-dimensional water-quality simulation system
G.A. Karavitis
1984, Water-Resources Investigations Report 84-4052
The SIMSYS2D two-dimensional water-quality simulation system is a large-scale digital modeling software system used to simulate flow and transport of solutes in freshwater and estuarine environments. Due to the size, processing requirements, and complexity of the system, there is a need to easily move the system and its associated files...
Hydrogeology of the Sulphur Springs area, Tampa, Florida
J. W. Stewart, L. R. Mills
1984, Water-Resources Investigations Report 83-4085
The Sulfur Springs area includes about 56 square miles in west-central Hillsborough County, Florida. The north-central part of the city of Tampa is highly urbanized; the north-west part of the area is rural or undeveloped. The area has numerous sinkholes, two of which are used as retention basins for urban...
Depth and thickness of selected units in Upper Permian, Upper Jurassic, and Lower Cretaceous rocks in southwestern Kansas
Jack Kume, Joseph M. Spinazola
1984, Water-Resources Investigations Report 83-4095
As ground-water reserves decline in the Ogallala aquifer in an area of about 17,400 square miles in 26 counties of southwestern Kansas, sandstone aquifers in underlying Upper Jurassic and Lower and Upper Cretaceous rocks may be developed to supplement or replace the Ogallala as a source of water for some...
Water-level maps of the alluvial aquifer, Northwestern Mississippi, April 1983
David M. Sumner
1984, Water-Resources Investigations Report 83-4285
Water levels were measured in about 500 wells in the Mississippi River valley alluvial aquifer in northwestern Mississippi during April 1983. Ground-water levels have declined in some areas in recent years as a result of heavy irrigation pumpage from this aquifer. Near the areas of principal recharge, along the major...
