Abstract
The revised universal soil loss equation (RUSLE), the sediment delivery distributed (SEDD) model, and ArcView GIS were used to estimate the impacts of no-till practice on soil erosion and sediment yield in Pataha Creek Watershed, a typical dryland agricultural watershed in southeastern Washington. The results showed that the average cell soil loss decreased from 11.09 to 3.10
t/ha
yr for the whole watershed and from 17.67 to 3.89
t/ha
yr for the croplands under the no-till scenario. Likewise, the average cell sediment yield decreased from 4.71 to 1.49
t/ha
yr for the entire watershed and from 7.11 to 1.55
t/ha
yr for the croplands under no-till practices. The major reason why no-till practice can significantly reduce the soil erosion and sediment yield is that it prevents rill generation which through rill erosion ultimately contributes up to 90% of the soil erosion in the Inland Pacific Northwest region.
