Methodology for the Estimation of Wetting Front Length and Potential Recharge under Variable Depth of Ponding

Abstract

A methodology for determining the length of advancement of wetting front and potential groundwater recharge under variable depth of ponding is presented. The methodology provides no restrictions to infiltration time period, depth, and nature of ponding and soil types. Performance of the proposed methodology has been compared with other models using the published laboratory and field experimental data. The quantitative statistics, namely, coefficient of determination (
