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 AA. present an alternative approach for generating micro-topography for the wetlands of the Okavango Delta. The region is characterized by extremely low local relief, with a maximum relief of no more than 2 to 3 m. Notwithstanding this low
relief, the wetland vegetation is extremely sensitive to small topographic variations and therefore provides a window into the micro-topography. Here, the AA. use knowledge of the relation between local relief and vegetation in order to generate a micro

In this commentary, the A. argues that the geographers have overlooked the real meaning of roughness which, strictly, is a component of topography that has to be parameterized, rather than a component that has any meaning in itself. Re-evaluation
of roughness as topography has the potential to allo boundary deformation to be explored in more realistic and numerically robust ways, and to provide a much more useful research tool.
, and soil forming processes were established based on field investigations and previously published datasets. The pedogenic processes in the study area are mainly controlled by groundwater distribution determined by topography. The AA. discuss the potential

Digital elevation models and topography profiles of a beach with intertidal bar and through (ridge-and-runnel) morphology in Merlimont, near Somme estuary, were analysed in order to assess patterns of cross-shore and longshore intertidal bar
