Analytical predictions of flow into auger holes and ditch drains in homogeneous anisotropic soil

Abstract

Analytical expressions are derived for predicting flow into an auger hole in an unconfined aquifer of finite horizontal and vertical extents and underlain by an impervious substratum Solutions are provided for two cases namely i when the auger hole fully penetrates the aquifer up to the impervious base and ii when the hole suspends above the base layer The validity of the developed analytical solutions are checked by drawing parallel numerical models for a few flow situations and then co
