One-line model description	River delta formation and evolution model with channel dynamics
Extended model description	DeltaRCM is a parcel-based cellular flux routing and sediment transport model for the formation of river deltas, which belongs to the broad category of rule-based exploratory models. It has the ability to resolve emergent channel behaviors including channel bifurcation, avulsion and migration. Sediment transport distinguishes two types of sediment: sand and mud, which have different transport and deposition/erosion rules. Stratigraphy is recorded as the sand fraction in layers. Best usage of DeltaRCM is the investigation of autogenic processes in response to external forcings.

Keywords:	delta evolution, cellula automata, coastal morphdynamics,
