  • The AA. present a topography based hillslope erosion and deposition model that is based on the WATEM/SEDEM model structure and works on a millennial time scale. Soil erosion, transport and deposition are calculated using slope and unit contributing
  • . The large regional, local and even temporal variability in the trend between A and SSY implies that prediction of SSY based on A alone is troublesome and preferably spatially distributed information on land use, climate, lithology, topography and dominant
  • This paper presents the case of a natural rock fragment (RF) mulch whose lithology indicates that the RF are up-squeezed by the local vertisol. Based on the data from the experimental site located in the pass of Enda Maryam, Tigray, Northern
  • This special issue is based on a selection of papers presented during the 2nd International Symposium on Gully erosion under global change, convened in Chengdu, China, 2002. The AA. introduce this volume by reviewing recent studies on impacts
  • The objectives of this paper are to highlight the significance of soil loss due to cross harvesting, SLCH, to establish suitable soil erosion definitions for SLCH and to review the factors determining SLCH based on a detailed literature study
  • The aims of this paper are : 1) to develop a methodology based on dendrochronology to estimate gully erosion rates; 2) to apply this method to gully sites selected in the Guadalentin basin in southeast Spain. The method is developed for Pinus
  • The aim of this study is to better understand the current activity of the landslides in the Flemish Ardennes. Based on accurate multi-temporal digital terrain models (DTMs), the AA. map first the areas of ground movement, then they analyse
  • In this paper a statistical multivariate method, i.e., rare events logistic regression, is evaluated for the creation of a landslide susceptibility map in the Flemish Ardennes. The methodology is based on the hypothesis that future landslides
  • In order to investigate the width-discharge relationships for rills and gullies, a new method is proposed based on field measurements of widths of concentrated-flow erosion channels both upstream and downstream of channel junctions. A total of 322
  • and geology, topography and land use was investigated. Based on a review of historical archives and on soil augerings, the origin of the CDs was reconstructed. In addition, the infilling of one CD was studied in detail to determine the mean erosion rate since
