Is a single layer sigmacoordinate eq., mathematically equivalent to SWE?  Coast/Estuary  Delft3D
intro story Coast / Estuary
Coast / EstuaryCoastal systems are among the most dynamic physical systems on earth and are subject to a large variety of forces. The morphodynamic changes occurring to coastlines worldwide are of great interest and importance. These changes occur as a result of the erosion of sediments, its subsequent transport as bed load or suspended load, and eventual deposition. Estuaries are partly enclosed water bodies that have an open connection to the coast. Estuaries generally have one or more branching channels, intertidal mudflats and/or salt marshes. Intertidal areas are of high ecological importance and trap sediments (sands, silts, clays and organic matter). Within the Delft3D modelling package a large variation of coastal and estuarine physical and chemical processes can be simulated. These include waves, tidal propagation, wind or waveinduced water level setup, flow induced by salinity or temperature gradients, sand and mud transport, water quality and changing bathymetry (morphology). Delft3D can also be used operationally e.g. storm, surge and algal bloom forecasting. On this discussion page you can post questions, research discussions or just share your experience about modelling coastal and/or estuarine systems with Delft3D FM. ** PLEASE TAG YOUR POST! **  Sub groups

Hi
I have a mathematical question.
Is a single layer system using sigmacoordinate equation (setting number of layers to 1 in sigmacoordinate model), mathematically equivalent to 2DShallow Water Equation?
IF the answer is yes, then can someone tell me how exactly these equations can interchange? (I mean a mathematical proof) or recommend me a relevant link to find my answer there?
Thanks in advance.
