Application of the water erosion prediction project (WEPP) in olive orchards on Vertic soil with different management conditions

The WEPP model was evaluated using monthly runoff and erosion data collected from an experiment in an olive orchard on a Vertic soil during four hydrological years, comparing three different soil management systems: no tillage with bare soil (NT), conventional tillage (CT), and cover crop (CC). These three systems differed greatly in average annual runoff and soil losses.
