Soil erosion by water is one of the major threatening factors to agricultural production and food security. USPED (Unit Stream Power Erosion Deposition) model was applied to analyse spatial distribution of erosion and deposition rates in northern Ethiopia. The mean erosion and deposition rates generated from the area totals 12.4 t ha−1 yr−1 and 7.3 t ha−1 yr−1, respectively. About 57% of the area lies under stable erosion and deposition severity classes, while its 14% faces moderate to very severe erosions. Slight to very slight erosion accounted for ca. 10% of the total area. Less than 0.2% experienced severe and very severe deposition, whereas its 7.1%, 6.8% and 5.3% faces moderate, slight and very slight depositions, respectively. Topography and land use have substantial implications to spatial distribution of erosion/deposition rates. The USPED model has good predictive performance to quantify soil erosion and accordingly can help to identify erosion hotspot areas.
