Estimating Optimal Geotextile Type for Controlling Soil Erosion

Abstract

One of the major functions of geotextiles is to control soil erosion. Apparent opening size and permeability of non-woven geotextiles are properties that control erosion. In this manuscript, soil taken from an eroded pond is considered for the study. Filtration and clogging behavior of the several geotextiles are studied under laminar flow conditions and at three different hydraulic gradients. Results facilitate selecting the appropriate geotextile based on permeability, filtration and clogging for use as erosion control.
