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 growing seas

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 relationships are ex

The principal water-yielding formation (unconsolidated aquifer) supplying water to wells in west-central Kansas is comprised of the Ogallala Formation and undifferentiated Pleistocene deposits. About 1,860 square miles of the area are underlain by sufficient saturated material to supply groundwater for irrigation. Saturated thickness in the area ranges from less than 50 feet to about 270 feet. Thi

Hydrologic investigations in Kansas during fiscal year 1978 consisted of collecting and analyzing data to assess the State 's water resources, describe the framework of hydrologic systems , and provide quantity and quality of water data for optimum development and management. Surface-water studies were made to analyze long-term records of streamflow, basin and stream-channel characteristics, relat

Data are presented that result from an intensive geohydrologic study for water-supply planning in a 12-square-mile area in northeastern Wichita County, Kansas. These data include records of wells, test drilling, chemical analyses, ground-water levels, rainfall, soilmoisture, well yield, solar radiation, crop yield, and crop acreage. Data indicate that water levels in the unconsolidated aquifer are

Use of channel measurements to estimate discharge characteristics of alluvial streams has shown that little agreement exists for the exponent of the width-discharge relation. For the equation Q = aWAb, where Q is mean discharge and WA is active-channel width, it is proposed that the exponent, b, should be of fixed value for most natural, perennial, alluvial stream channels and that the coefficient

Data from 64 stream-sediment stations and reservoirs in the plains area and from 15 stream-sediment stations in the mountainous area were analyzed to determine the relation of sediment yield to basin characteristics. Data from each sediment station and reservoir represented at least 7 years of sediment discharge in the plains area or 4 years of sediment discharge in the mountainous area. Results o

During 1978, methods of estimating ground-water withdrawals in western Kansas were examined and evaluated, using both existing data from the files of the U.S. Geological Survey and newly collected data.Values for annual ground-water withdrawals reported to the Division of Water Resources, Kansas State Board of Agriculture, by water users probably contain substantial errors because most individual

Chapter Al of the manual contains methods used by the U.S. Geological Survey to collect, preserve, and analyze water samples for their content of dissolved minerals and gases. Among the topics discussed are selection of sampling sites, frequency of sampling, sampling equipment, sample preservation, laboratory equipment and instrumental techniques, accuracy and precision of analysis, and reporting

Many existing water supplies in southeastern Kansas are proving inadequate to meet current and expanded future needs. One of the methods in which the use of highly variable streamflow in the area can be evaluated is with the aid of multiyear low-flow frequency information. Data from 19 stream-gaging stations in the study area and a base period of 1940-77 were used to develop maps from which discha

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 from a "base
