A finite-element model for simulating hydraulic interchange of surface and ground water
K. C. Glover
1988, Water-Resources Investigations Report 86-4319
A model was developed to be useful for predicting changes in streamflow as a result of groundwater pumping. The stream aquifer model is especially useful for simulating streams that flow intermittently owing to leakage to the aquifer or diversion for irrigation or streams that become perched owing to declining hydraulic...

L.J. Martin, D. L. Naftz, H. W. Lowham, J.G. Rankl
1988, Water-Resources Investigations Report 88-4046
There are 16 existing and six proposed surface coal mines in the eastern Powder River structural basin of northeastern Wyoming. Coal mining companies predict water level declines of 5 ft or more in the Wasatch aquifer to extend form about 1,000 to about 2,000 ft beyond the mine pits. The...
Methods to determine transit losses for return flows of transmountain water in Fountain Creek between Colorado Springs and the Arkansas River, Colorado
Gerhard Kuhn
1988, Water-Resources Investigations Report 87-4119
Methods were developed by which transit losses could be determined for transmountain return flows in Fountain Creek between Colorado Springs, Colorado, and its confluence with the Arkansas River. The study reach is a complex hydrologic system wherein a substantially variable streamflow interacts with an alluvial aquifer. The study approach included:...
Water use on the Snake River plain, Idaho and eastern Oregon
S. A. Goodell
1988, Professional Paper 1408-E
Amounts of water withdrawn and consumptively used for irrigation and other uses on the Snake River Plain were estimated to help deter- mine hydrologic effects of ground- and surface-water use. Irrigation is the largest off stream use of water on the plain. Surface-water irriga- tion began in the 1840's and...

J. G. Elliott
1988, Water-Resources Investigations Report 87-4193
Regression analysis was used to develop models for estimating mean annual suspended-sediment loads for streams in Colorado. Mean annual suspended-sediment loads at 81 selected streamflow-gaging stations in the central, northwestern, and southwestern regions of Colorado were expressed as functions of geomorphic and hydrologic variables. A multiple-regression model that included mean...
