The sedimentation algorithms included in the Water Erosion Prediction Project Surface Impoundment Element(WEPPSIE) are described and verified in this article. The algorithms are based on the overflow rate concept. WEPPSIEtrapping efficiency results agreed with predictions made using a previously validated continuous stirred reactors model.WEPPSIE also performed adequately with 11 field data sets. The average trapping efficiency prediction error was 5.5% witha maximum error of 13%.
