The effects of human activities on suspended sediment concentration (SSC) during the late 20th century were examined at 57 sites along major rivers in central Japan using governmental data and GIS. Analysis of the relationships between mean SSC and catchment properties, such as land use, has revealed that patterns in suspended sediment concentrations in these rivers are primarily linked to agricultural...
The relationships between the spatial distribution of ground-cover and terrain attributes were examined in the Tabernas badlands (SE Spain) in order to understand the terrain-dependent driving forces of the spatially heterogeneous ground cover. Ground cover was mapped in the field and terrain attributes were derived from a 1-m resolution Digital Elevation Model (DEM). The association of spatial distribution...
Rainfall erosivity is the potential ability for rainfall to cause soil loss. Erosivity can be quantified by means of the R factor calculation of the universal soil loss equation (USLE). The purpose of this study was to investigate the spatial distribution of annual rainfall erosivity in Brazil. For each of eight Brazilian regions covering the whole of the territory of Brazil, one adapted equation...
