REFLUX-SEDIM

REFLUX-SEDIM is a two-dimensional code which resolves different equation of sediment transport under current action. It applies to non-cohesive sediments, with an uniform grain size between 0,2 to 4 mm.

Reflux-sedim has been developped from Reflux finite element structure.

The time-sisle difference between hydrodynamics and sedimentary changes allows to uncouple the equations governing those two phenomenons. Several event filtering formulation are used (tides and flood). Its main results are, for each mode of mesh, the bottom changes and the sediment transport. The calculus stops as soon as the bottom changes reach a certain treshold, set by the user.
