Macroscale analysis of upland erosion

ABSTRACT Scale effects in computing sheet and rill erosion losses from large basins have been studied for grid sizes ranging from 0.03 to 42 km over drainage areas up to 3000 km2, As a result of the analysis conducted on the Chaudiere basin (5830 km2), the mean characteristics of the basin can be used to estimate the mean annual upland erosion losses after a correction factor for the influence of grid size is introduced into the calculation, The use of fine-meshed grids can be justified when information on the areal distribution of soil erosion is desired.
