Abstract

This paper focuses on identifying visual erosion features (i.e. exposed roots, earth pillars, soil drift and etching, linear channels) which are part of internally defined spatial landscape units (erosion proxies), whose internal characteristics influence the occurrence of soil erosion, and whose spatial content enables their analysis by remote sensing and GIS. The detected erosion features are useful for measuring and predicting soil erosion processes (sheet, mass and linear), with the least possible constraints related to input data of existing GIS regional models. Their efficiency is tested in this study through the validation of the available 1:100,000 water erosion risk maps in Lebanon as a case study of Mediterranean karst environments
