Incorporated models or components:

Spatial dimensions	2D
Spatial extent	Reach-Scale
Model domain	Coastal
One-line model description	Finite Volume two-dimensional shock-capturing model.
Extended model description	The numerical model solves the two-dimensional shallow water equations with different modes of sediment transport (bed-load and suspended load) (Canestrelli et al. 2009, Canestrelli et al, 2010). The scheme solves the system of partial differential equations cast in a non-conservative form, but it has the important characteristic of reducing automatically to a conservative scheme if the underlying system of equations is a conservation law. The scheme thus belongs to the so-called category of “shock-capturing” schemes. At the present I am adding a new module for the computation of mud flows, and I want to apply the model to the Fly River (Papua New Guinea) system.

Describe processes represented by the model	The numerical model solves the two-dimensional shallow water equations with different modes of sediment transport. Moreover are presently implemented the Savage-Hutter type model describing avalanches of granular materials (not tested yet) and the equations governing the motion of two layers of immiscible fluid.
Describe key physical parameters and equations	Momentum and continuity differential equations are solved for each layer. Closure equations are solved for bed-load discharge and entrainment/deposition.
Describe length scale and resolution constraints	Hundreds of Km (the reach of a river).
Describe time scale and resolution constraints	Days/months. When running for more then few month the simulation time is very large.
Describe any numerical limitations and issues	At the present I am trying to improve the wetting and drying algorithm, unphysical large velocities are sometime produced at the wet/dry front.
