Cche2d user manual

CCHE2D is an integrated software package developed at the National Center for Computational Hydroscience and Engineering, the University of Mississippi. It is a general model for two-dimensional simulation and analysis of river flows, dam break flows, non-uniform sediment transport, morphologic processes, coastal processes, pollutant transport. This is a technical manual as a quick-start guide for using CCHE2D-Coast, an integrated coastal and ocean process model. It contains the descriptions of the model and GUI. CCHE2D-Flood and Embankment Breach Models Catastrophic floods can cause loss of many lives and tremendous property damage. In addition, floods will also cause failures of infrastructures and environmental degradation via sediment/soil erosion and water pollution. Floods due to instant dam failures and levee embankment breaching are particularly detrimental because.

CCHE2D is an aggregated software package created in by Wang et al in the National Centre of Calculation and Hydraulic Engineering under the supervision of the University of Mississippi, USA. This model is a 2D hydraulic model that is created for analyzing the simulation of flow, hydraulics, sediment transport, and morphology processes in.

GOVERNING EQUATIONS The phenomena of flow and sediment transport in rivers are characterized by turbulence, free-surface variation, bed change, phase interaction, etc. In the time being, it is very difficult to include CCHE2D models compute the total-load sediment using a single governing equation or.

as a guide to using the CCHE2D-GUI. In addition, the manual describes in detail the format of the files used and produced by the CCHE2D model. Using The Manual This manual includes a detailed description of the capabilities of CCHE2D-GUI. The manual explains in detail each of the option under the menus and sub-menus. 3 CCHE2D Mathematical Model CCHE2D model is an integrated package for two-dimensional simulation and analysis of free surface flows, sediment transport and morphological processes. The package comprises of the numerical models, a mesh generator (CCHE2D Mesh Generator) and a Graphical User Interface (CCHE2D-GUI) as illustrated in Figure 1. CCHE3D Flow Model CCHE3D is a finite element based model for simulating free surface turbulent flows. Most of its applications are near-field flow and sediment transport around hydraulic structures. The simulated cases with measured experimental data have shown the accuracy and reliability of the model. The following list shows the capabilities.
