Abstract

The WEPP model was primarily designed for predicting erosion under rainfall conditions,
but procedures have been added to predict soil erosion from furrow irrigation. Predicted runoff
and infiltration using WEPP compared reasonably well with measurements from an 85-m long
field segment, but predicted values were poorer from two fields that were longer than 200 m. Soil
erosion was not adequately predicted using WEPP-defined soil parameters. Predicted soil erosion
was still unacceptable after attempting to adjust soil parameters to fit furrow irrigated conditions.
Some relationships in the WEPP model need to be changed before accurate soil erosion
predictions can be achieved for furrow irrigated fields.
