A statistical technique, called kriging, was programmed for a computer to interpolate hydrologic data based on a network of 296 measured values in west-central Kansas and eastern Colorado. The computer program generated estimated values of selected hydrologic data at the center of each 1-mile section in the Western Kansas Groundwater Management District No. 1. This program facilitated...

A mathematical technique, called kriging, was programmed for a computer to interpolate hydrologic data based on a network of measured values in west-central Kansas. The computer program generated estimated values at the center of each 1-mile section in the Western Kansas Groundwater Management District No. 1 and facilitated contouring of selected hydrologic data that are needed in the...

The High Plains aquifer in Kansas is a part of a regional system that extends South Dakota to Texas. The aquifer in Kansas underlies an area of 31,000 square miles in the western and south-central part. This aquifer is a hydraulically connected assemblage of unconsolidated water-bearing deposits of Tertiary and Quaternary age. Maps published at a scale of 1:500,000 show the altitude and

Geometry, channel-sediment, and discharge data were collected and compiled from 252 streamflow-gaging stations in the Missouri River basin. The sites represent the complete ranges of hydrologic and geologic conditions found in the basin. The data were analyzed by computer to yield equations relating various discharge characteristics to variables of channel geometry and bed and bank...

Irrigation pumpage was determined for parts of Kearny and Finney Counties in Southwestern Kansas using crop-acreage data and consumptive, irrigation-water requirements. Irrigated acreages for 1974-80 were compiled for wheat, grain sorghum, corn, and alfalfa using records from the U.S. Agricultural Stabilization and Conservation Service. Consumptive-irrigation requirements were computed...

The Ogallala Formation comprises the High Plains aquifer in Oklahoma and southwestern Kansas. Regional ground-water flow is from west to east in the Ogallala Formation, and the concentration of dissolved solids in ground water increases in the direction of flow. This increase may be influenced by residence time, but underlying bedrock appears to control ground-water chemistry. The...

Strippable reserves of Mulberry coal underlie an area of approximately 300 square miles of Miami, Linn, and Bourbon Counties of eastern Kansas. Although subject to State reclamation law, current and projected strip mining of this relatively thin coal seam could alter and hydrologic environment of the study area. Drained by the Marais des Cygnes and Little Osage Rivers and their...

Historical information on ground-water pumpage for irrigation is required for use with a computer model of the High Plains aquifer. Available historical data on ground-water pumpage in the High Plains were inadequate for use with the computer model. Consequently, a method was developed to estimate historical pumpage data. Two principal components were used to develop estimates of ground...

Water-level measurements were made, mostly in January 1982, in about 1,530 wells in western and south-central Kansas. The measurements were made in mid-winter when pumping was minimal and water levels had recovered, for the most part, from the effects of pumping during the previous irrigation season. Annual hydrologic data are provided for relating water-level changes from a ' base...

Analysis of hydrologic data from the Kansas River basin suggests that the channels of the lower Solomon, Saline, and Smoky Hill Rivers have narrowed and stabilized as a result of construction of upstream reservoirs. The Kansas River channel, however, remains relatively unstable and locally active. Streamflow regulation and sediment trapping by reservoirs are possible causes of changes...

Gaging-station data are presented on variations in annual runoff over the conterminous United States and nearby Canada during the period 1911-79 in tabular and graphic (map) form. These data bring up-to-date and extend backward in time previous reports on streamflow stations by Harbeck and Langbein in 1949 which covered the period 1921-45 and that by Busby in 1963 which covered the...
