A sediment load model for the world’s drainage basins
Dr. Jon Pelletier of the Univ. of Arizona published a new spatially-distributed model of suspended sediment loads in the Journal of Geophysical Research, June 2012. The model explicitly differentiates between hillslope and alluvial channel dominated catchments. Erosion is controlled by slope, monthly rainfall and vegetation cover, whereas river transport depends on slope and soil texture. Dr. Pelletier tested the model against the long-term yield of 128 global rivers with good results. More...
