Simple-regression and structural analysis are similar methods of developing a linear relation from a bivariant group of data. Regression analysis is a useful curve-fitting technique, but often is misapplied to geomorphic data sets. When error components can be identified for both variables, the statistical technique of structural analysis is preferred. If regression results are available

The storm of September 12-13, 1977, produced as much as 16 inches of rainfall in the Kansas City, Missouri-Kansas area, left 25 persons dead, many homeless, and caused over 50 million dollars in damages. Data from National Weather Service recording rain gages indicate the storm came in two bursts within 24 hours. Flood hydrographs developed from streamflow records in the area also...

Rainfall and runoff data from urbanized drainage basins in the Wichita area, Kansas, were used to evaluate the Soil Conservation Service synthetichydrograph method of computing flood hydrographsfrom rainfall data. The method was tested on six basins where the impervious surface ranged from 11 percent on the least urbanized basin to 40 percent on the most urbanized. Twenty-two of the...

Onsite measurements of pH, specific conductance, and water temperature show that water temperatures in seven mine shafts in northeastern Oklahoma and southeastern Kansas is stratified. With increasing sampling depth, specific conductance and water temperature tend to increase, and pH tends to decrease. Concentrations of dissolved solids and chemical constituents in mine-shaft water, such...

Surface-water supplies are diminishing in the Hitchcock-Red Willow and Frenchman Valley Irrigation Districts in southwest Nebraska. Stream depletions due to ground-water withdrawals upstream from Enders Reservoir (northwest of the study area) have resulted in a shortage of about 8,700 acre-feet per year. The availability of ground water to supply part of this deficit was examined. Two...

The principal aquifer in the 13-county area of southwestern Kansas occurs in the heterogeneous, unconsolidated alluvial deposits of Tertiary and Quaternary age. The main body of this ground-water reservoir is designated as the unconsolidated aquifer. The map showing the saturated thickness of deposits in the unconsolidated aquifer was prepared by comparing maps showing the altitude and

Water resources data for the 1976 water year for Kansas consists of records of stage, discharge, and water quality of streams; stage, contents, and water quality of lakes and reservoirs; and water levels and water quality in wells. This report contains discharge records for 148 gaging stations; stage and contents for 20 lakes and reservoirs; water quality for 67 gaging stations and 2...

This report contains basic data on water-level measurements in observation wells in western Kansas. Most of the measurements were made in January 1977; a few were made in December 1976 and in February 1977. The measurements were made in mid-winter when pumping was minimal and water levels had recovered from the effects of pumping during the previous irrigation season. This report also...

Unconsolidated deposits of Pliocene and Pleistocene age comprise the principal aquifer in the Great Bend Prairie. Forty-five million acre-feet of ground water are estimated to be in storage in these deposits. Only about 60 percent of this amount may be usable owing to an insufficient saturated thickness and to high mineralization of water locally. Yields to irrigation wells are commonly...
