Water-quality reconnaissance of Harding Creek, Lawrence County, Arkansas
James C. Petersen
1981, Open-File Report 81-1058
A study of Harding Creek conducted between April and October 1980 to assess the water quality of the creek indicates no serious water-quality problems. Eight water samples were collected during periods of low to moderate streamflow (less than 19 cubic feet per second). The water was hard to very hard...
Simulated interactions between the proposed Narrows Reservoir and the water-table aquifer along the South Platte River, Morgan County, Colorado
Alan W. Burns
1981, Water-Resources Investigations Report 80-119
A computer model, including a ground-water-flow component and a mass balance reservoir-operations component, was developed to simulate the proposed Narrows Reservoir and the adjacent alluvial aquifer of the South Platte River, Morgan County, Colo. This model, using a weekly time step, simulated the transient interactions of these two systems for...

Predicted effects on ground water of construction of Divide Cut section, Tennessee-Tombigbee Waterway, northeastern Mississippi, using a digital model
Mark S. McBride
1981, Open-File Report 81-649
The Tennessee-Tombigbee Waterway, connecting the Tennessee River in northeastern Mississippi with the Gulf of Mexico, is currently (1980) under construction. The Divide Section, the northernmost 39 miles of the Waterway, will consist, from north to south, of (1) a dredged channel, (2) the Divide Cut, and (3) an artifical lake...
A stochastic streamflow model of the Platte River at Overton, Odessa, and Grand Island, Nebraska
A.V. Vecchia Jr.
1981, Open-File Report 81-1188
A stochastic model is developed to simulate flows for three seasons (September through February, March and April, May through August) at Overton, Odessa, and Grand Island, Nebraska on the Platte River. The model preserves the first and second order moment properties of the historical flow series, including significant autocorrelations within...
