Description :
LEM LAPSUS is a relatively simple cellular model operating on timescales of centuries to millennia and using annual timesteps that has had a hillslope focus. In this paper, the AA. developed, tested and demonstrate the ability of LEM LAPSUS to simulate sediment dynamics for coupled hillslope-river systems without adding new process equations. The model should be able to reproduce alternating aggradation and incision in the floodplains of catchments, depending on simulated conditions. Testing was done using an artificial digital elevation model (DEM) and a demonstration of the ability for fluvial simulation was performed for a real landscape (Torrealvilla catchment in the Guadalentín Basin, Murcia Province, southeast Spain).
