A water balance model was developed to predict daily water table depths in some corn fields with or without subsurface drainage systems, using pertinent soil and water properties and weather data. The model outputs were compared with the recorded dat

Presently available solutions of the one‐dimensional unsteady‐state ground‐water flow equation (Boussinesq equation) have been obtained by treating the drainable porosity f as a constant. Experimental evidence however, indicates that f is a fun

Laboratory column studies are done to investigate the variation of drainable porosity in relation to water table depth. Corresponding functional relationships are developed between drainable porosity and water table depth. The Boussinesq equation for

Field and laboratory investigations were done to study the dependence of drainable porosity on the suction in two different types of soil. Empirical nonlinear relationships were developed between the two. These relations were different for the sand a

A computer simulation water balance model was used to analyze the variation of daily water-table depths in the field using 27 yrs of weather data and soil water parameters. The high water table in the study area resulted from a cool moist climate and

PROCEDURES were developed to compute corn crop loss for different depths and durations of high water table conditions, based on available data, and to calculate the revenue increases from a subsurface drainage system designed with different spacings
