Soil Water Movement in Glacial Till: A Case Study in Central South Dakota

by Daniel E. Jewell, U.S. Bureau of Reclamation, United States,



Document Type: Proceeding Paper

Part of: Irrigation and Drainage

Abstract:

Between 1985 and 1987, the CENDAK Drainage Steering Committee conducted several investigations to assess the drainage needs for a proposed large-scale irrigation project in central South Dakota. The water balance studies are the focus of this paper. Four sites (two irrigated and two non-irrigated) were equipped with a variety of instrumentation (including weather stations, neutron-probe access tubes, and soil transiometers). The sites were monitored daily for a one-year period to determine soil-moisture fluxes between the ground surface and the shallow water table.
