Abstract:

The purpose of the study was to determine and evaluate soil, site, and weather factors that affect high water tables, and to explore means by which an existing method for predicting soil-moisture content of the 0- to 6-in. and 6- to 12-in. layers could be modified to improve its accuracy when applied to soils with high water tables. Factors that significantly affected the initiation, duration, and periodicity of high water tables were precipitation, topographic position, depth to a relatively impermeable soil layer, slope of ground, rate of evapotranspiration, and, where applicable, stream or river stage. A scheme for predicting daily depths to water tables was incorporated in the soil-moisture prediction method, resulting in reasonably accurate predictions of soil moisture content and soil strength.
