  • In this paper, 2 topographic indices, closely related to mathematical expressions suggested by different AA. are used to characterize the influence of watershed topography on gully erosion. The AS1 index is defined as the product of watershed area
  • the topographic indices and the volume of eroded soil.
  • Topographical thresholds for ephemeral gully initiation in intensively cultivated areas of the Mediterranean
  • and topographical, lithological, land-use and climatic factors.
  • Gully erosion in South Eastern Tanzania : spatial distribution and topographic thresholds
  • of a landscape to gully erosion. Two important components of gully erosion studies are the prediction of where gullies begin and where they end. To address some of these issues, topographical thresholds for gully initiation and sedimentation in 6 different
  • characteristics, such as topographical parameters, material properties and climate. The ultimate goal is to identify the most important controlling factors of past and present bank gully erosion. 55 active bank gullies formed in different lithologies by various
  • area. The topography is iteratively rejuvenated by taking into account modelled erosion and deposition rates, thereby simulating topographic development backwards in time. The model is spatially evaluated, using detailed estimates for historical soil
