The Community Sediment Transport Modeling System (CSTMS) is an open-source model that couples hydrodynamics (circulation and waves), sediment transport, and morphodynamics. The model will be suitable for realistic and useful simulations of processes that influence sediment transport in the coastal ocean, including estuaries, nearshore regions, and the continental shelf over regional length scales (10Ãs of meters to 100Ãs of kilometers) and time scales ranging from transport events to decades. The code will be written in modern, portable languages (mostly FORTRAN95) using a modular approach that will allow flexibility and extensibility. In addition to the source code(which will have an open-source license and run on most computer systems from laptops to multi-processor clusters), the project will provide model documentation, training, test cases, tools for processing model input and output, and demonstrated applications.
