Abstract

This study investigates to what extent GIS-based modelling using topographic as well as soil and land-use information may be a useful tool for predicting linear erosion initiation and development in agricultural landscapes. The AA. hypothesize that soil incision can be modelled in a physically deterministic way by using a threshold value of estimated flow velocity. Their second objective is to evaluate the impact of land-use and climatic changes upon linear erosion. Field observations of linear erosion in a watershed of Laos under sloping land conditions were compared to estimated flow velocities estimated using a process-based model
