Estimation of soil erosion using common empirical models has long been an active research topic. Nevertheless, application of those models at basin scale is still a challenge due to data availability and quality. In this study, the Revised Universal Soil Loss Equation (RUSLE) and the Unit Stream Power-based Soil Erosion/Deposition (USPED) were applied and compared to determine the spatial distribution of soil erosion of a coastal watershed in Basilicata, southern Italy. A comprehensive approach that integrates ancillary data, digital terrain model, products derived from satellite remote sensing (multi-temporal Landsat imagery) and GIS techniques was adopted to identify major factors influencing soil erosion. Soil loss and soil erosion/deposition maps were produced. The study provided a reliable prediction of soil erosion rates and definition of erosion-prone areas within the watershed.

Abstract

Estimation of soil erosion using common empirical models has long been an active research topic. Nevertheless, application of those models at basin scale is still a challenge due to data availability and quality. In this study, the Revised Universal Soil Loss Equation (RUSLE) and the Unit Stream Power-based Soil Erosion/Deposition (USPED) were applied and compared to determine the spatial distribution of soil erosion of a coastal watershed in Basilicata, southern Italy. A comprehensive approach that integrates ancillary data, digital terrain model, products derived from satellite remote sensing (multi-temporal Landsat imagery) and GIS techniques was adopted to identify major factors influencing soil erosion. Soil loss and soil erosion/deposition maps were produced. The study provided a reliable prediction of soil erosion rates and definition of erosion-prone areas within the watershed.
