Short course on CCHE2D flow and sediment transport models



Description



CCHE2D is an integrated software package developed at the National Center for Computational Hydroscience and Engineering, the University of Mississippi.

CCHE2D is a numerical model for two-dimensional simulation and analyses of free surface flows, water quality and sediment transport. The modelling setup is performed using the in-house interface CCHE-GUI, while the mesh generation CCHE-MESH is adopted to discretize the computational domain.

Key capabilities: non-uniform and non-equilibrium sediment transport; cohesive sediment transport; morphologic change and bank erosion; turbulence closure schemes; dam break flows; presence of hydraulic structures; super- and trans-critical flows; wet & dry capability; vegetation drag and wind effects; quadrilateral, triangular and hybrid mesh systems; GPU accelerated models.

During the course, the flow and the sediment transport modules will be presented, as well as the mesh generator and the user interface. The CCHE2D flow and sediment transport models will be implemented in simplified case studies to test the performances of the code, demonstrating its large applicability.
