Evaluating methods for determining water use in the High Plains in parts of Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming, 1979 Evaluating methods for determining water use in the High Plains in parts of Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming, 1979

The volume and areal distribution of ground-water withdrawals (pumpage) for irrigation during 1980 are required for the High Plains Regional Aquifer-System Analysis. In 1979, approaches and instrumentation that might be suitable for application to 1980 water-use determinations were tested. Pumpage was sampled by monitoring time of operation and discharge of irrigation wells during the...

Simulated water-level declines near Marienthal, west-central Kansas Simulated water-level declines near Marienthal, west-central Kansas

Intensive study in an area of 12-square miles near Marienthal, Kansas, has shown a decrease of 30 to 50 percent in saturated thickness of the Ogallala Formation since the development of irrigation. Projections from a digital model indicated the additional water-level declines that might occur from 1978 to 1989 if the pumpage in the model area was assumed to be one-half, equal to, or...

Preliminary analysis of regional-precipitation periodicity Preliminary analysis of regional-precipitation periodicity

Precipitation variability plays a major role in nearly every aspect of the hydrologic cycle. Precipitation is not a random event, but it occurs after a sequence of prerequi-sites has been fulfilled. Recent investigations have shown that activity of the sun can affect atmospheric vorticity, an important factor in precipitation formation. Solar activity is known to be periodic; therefore...

January 1980 water levels, and data related to water-level changes, western and south-central Kansas January 1980 water levels, and data related to water-level changes, western and south-central Kansas

This report contains hydrologic data on water-level measurements in observation wells in western and south-central Kansas. The measurements were made in mid-winter, mostly in January, when pumping was minimal and water levels had recovered from the effects of pumping during the previous irrigation season. This report also provides basic hydrologic data for relating water-level changes...

Multiyear Low Flow Of Streams In Northeastern Kansas Multiyear Low Flow Of Streams In Northeastern Kansas

Many existing water supplies in northeastern Kansas are proving inadequate to meet current and expanded future needs. One of the methods by which the use of highly variable streamflow in the area can be evaluated is with the aid of multiyear low-flow frequency information. Using data form 19 streamflow-gaging stations in the study area, maps were developed from which the mean annual...

A procedure for predicting concentrations of dissolved solids and sulfate ion in streams draining areas strip mined for coal A procedure for predicting concentrations of dissolved solids and sulfate ion in streams draining areas strip mined for coal

Current trends in increased coal production neccessitate the development of techniques to appraise the environmental degradation that results from strip mining. A procedure is introduced for the prediction of dissolved-solids and sulfate-ion concentrations in streams draining strip-mined areas as functions of the percentage of the drainage area that has been strip mined. These...
