  • A model, the Tillage-Controlled Runoff Pattern model (TCRP model) was developed to create a runoff pattern with flow in the direction of the plough-lines for all tilled fields within a catchment. The model needs a digital elevation model (DEM
  • ), a landuse map and the major tillage orientation per tilled field as input. Runoff patterns created with the model could be used in any raster-based erosion model. The effect of the runoff pattern on simulated erosion patterns is shown for one field using
  • the erosion model LISEM.

  • 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
  • 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
  • erosion and show that the model can simulate realistic soil redistribution patterns.

  • The AA. present a spatially distributed model for the calculation of sediment delivery to river channels (SEDEM : SEdiment DElivery Model) at a catchment scale (100 to 10 000 km2). The model was applied on several catchments in central Belgium
  • GIS-based simulation of erosion and deposition patterns in an agricultural landscape: a comparison of model results with soil map information

  • Agropedology ; Belgium ; Flanders ; Geographical information system ; Model ; Sediment transport ; Simulation ; Soil erosion ; Topography
  • This paper presents a relatively simple, two-dimensional hillslope erosion-deposition model: the model differs from most geomorphological models in that it does not assume that erosion by surface wash is always transport-limited. As a first test
  • , the model is applied to an agricultural catchment in Central Belgium. Here, patterns of past erosion and deposition can be deduced from information contained in the Belgian Soil Map so that a qualitative validation of the model results is possible.
  • The European Soil Erosion Model (EUROSEM) : a dynamic approach for predicting sediment transport from fields and small catchments

  • Concept ; Europe ; Gully erosion ; Model ; Rill wash ; Sediment transport ; Soil erosion ; Splash ; Water erosion ; Watershed
  • The European Soil Erosion Model (EUROSEM) is a dynamic distributed model, able to simulate sediment transport, erosion and deposition over the land surface by rill and interill processes in single storms for both individual fields and small
  • catchments. This paper describes the outcome of the resulting research effort which has led to the EUROSEM. In addition, emphasis is given to the features which make it different from and an advance upon the American and Australian models.
  • The influence of both process descriptions and runoff patterns on predictions from a spatially distributed soil erosion model

  • This study presents a sensitivity analysis of the soil erosion model LISEM, whereby not only the sensitivity to parameter values is considered, but attention is focused on the effects of process descriptions and the routing of overland flow
  • . As erosion models include a wide range of processes (i.e. rainfall, interception, surface storage, overland flow, soil erosion and deposition), this implies that only a relatively small fraction of all possible variations is explored here.

  • The AA. describe a dataset that offers possibilities for improved evaluation and parameterisation of spatially distributed soil erosion models. The dataset combines rainfall, runoff and sediment discharge data collected at the outlet and field
  • surveys within the catchments that describe soil surface charcteristics and soil erosion features. The paper dicusses and illustrates the use of the dataset to narrow uncertainties associated with model predictions.

  • will have the same causal factors as the landslides initiated in the past. Significant model results were obtained, with pre-landslide hillslope gradient and 3 different clayey lithologies being important predictor variables. Receiver Operating
  • Characteristics (ROC) curves and the Kappa index were used to validate the model. The results allow to conclude that the model is capable of predicting hillslope sections prone to landsliding.
