Numerical simulation of sediment mixture deposition part 2: a sensitivity analysis

This paper presents a series of numerical simulations, with the objective of testing the sensitivity to different parameters in the numerical modeling of previously published laboratory experiments. Different options and formulations are analyzed, especially when they concern and influence downstream grading of sediment in rivers. A final discussion deals with the transposition of such investigations to environmental and river engineering studies : refined lab experiments are valuable, despite a direct applicability to real problems which is very limited.
