Welcome to the Community Sediment-Transport Modeling Project (CSTM)

The goal of this project is to produce 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 (10’s of meters to 100’s of kilometers) and time scales ranging from transport events to decades. We are initially focusing on building this capability around the ROMS hydrodynamic modeling system, but will work toward modularizing the system components via the Earth System Modeling Framework (ESMF).
