- Some reflections on modelling hillslope processes in Geomorphological models. Theoretical and empirical aspects. (1)
- The AA. believe that in modelling hillslope processes, a combination of both theoretical and experimental approaches is needed as illustrated by several examples from the Louven laboratory.
- factors are calculated for the top layer of soils where rill and interrill erosion occur. The K-values generated by each model are then compared throughout the range of soil types varying erodibility. For both models average K-values per unit area
Assessment of soil losses by ephemeral gully erosion using high-altitude (stereo) aerial photographs
- . Ephemeral gullies formed within an area of 218 ha were mapped and measured both in the field and by high-altitude aerial photos taken at the same time. Comparison of these 2 methods shows that if only one of the 2 surveying techniques had been used, only 75
- specifically, the study investigates to what extent sediment deposition (both total mass and sediment quality) can be predicted using the simple theory for flows with a shear stress below the threshold value, and which modelling approach can best be used once
