Suspended matter transport in fluvial flow for estuaries simulation with mixed formulation based on eulerien, lagrangien and multiagent models

The aim of this paper is to propose a new modelization approach to represent complex systems. We take example of estuarien's ecosystem. This approach is based on the combination of different models. We use an eulerien modelization of the flow, a lagrangien one for the transport of suspended matters and an agent-based approach of interactions. These different models can represented precisely the evolution of suspended matters during tidal period in an estuary.
