Modification of the Revised Morgan-Morgan-Finney model for estimating sediment yield in large river basins

Abstract

The RiNux model has been developed to simulate and predict monthly nutrient fluxes from land to coastal waters under various scenarios of global change. The RiNux model consists of different modules for simulating the hydrology, sediment transport, and nutrient transport within river basins at a 3 km resolution using available global data sets for input variables. The sediment transport module simulates the supply of sediment from the hillslopes to and transport through the river network and accounts for sediment detachment and transport capacity on hillslopes, transfer to and transport in the river channel network, conveyance losses due to sediment deposition in lakes and reservoirs, and overbank sedimentation on floodplains.
