Summary Contact Technical specs In/Output Process Testing Other Component info Also known as Model type Single Incorporated models or components: Spatial dimensions 2D Spatial extent Reach-Scale Model domain 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.

Yes If above answer is no, provide end year model development Model availability As code Source code availability (Or provide future intension) Through CSDMS repository Source web address View source code Program license type GPL v2 Program license type other Memory requirements 2 GBytes Typical run time 1 hour - several days Describe input parameters A long list of coefficient depending on the differential equations that are being solved and on the chosen closure relationships. Input format ASCII Other input format Describe output parameters depth, liquid and solid discharges along x and y. In the multi-layer version(under development), these are provided for each layer. Output format Binary Other output format Pre-processing software needed? No Describe pre-processing software Post-processing software needed? No Describe post-processing software Visualization software needed? Yes If above answer is yes Other visualization software Incidenze 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. Describe available calibration data sets Upload calibration data sets if available: Describe available test data sets Upload test data sets if available: Describe ideal data for testing Do you have current or future plans for collaborating with other researchers? I am presently doing a post-doctorate at Boston University with professor Sergio Fagherazzi.
