LATERAL MOVEMENT AT THE PERIPHERY OF A ONE-DIMENSIONAL FLOW OF WATER

Abstract

An approximate analytical solution for the lateral movement at the periphery of a one-dimensional flow of water without gravity is derived for a source that is a semi-infinite plane. The solution is shown to be valid experimentally for relatively long times for a source with finite length. The theory can be utilized to calculate, and correct for, the additional infiltration due to lateral movement in measurements of water intake in the field; when gravity is present, however, the correction is valid only for short times.
