Abstract

A study was made of the shallow ground-water regime in a ridge-depression microrelief area where high salinity occurred in the ridges compared to low salinity in the depressions. Ground-water movement was affected by: (a) surface relief, which caused impounding of precipitation in the depressions; (b) greater hydraulic conductivities in the depressions; and (c) differences in moisture use due to greater tree and vegetative growth in the depressions. Water tables fluctuated from above the ground surface to depths of 10 feet. Salt concentrations of ground water were much higher in the ridges than the depressions. These differences occurred to a depth of 20 feet.
