Model description
| Model type: | Single model for the Marine domain |
| Description: | Sedtrans05 is a sediment transport model for continental shelf and estuaries. It predicts the sediment transport at one location as function water depth, sediment type, current and waves (single point model). It can be used as sediment transport module for larger 2D models. Five different transport equations are available for non-cohesive sediments (sand) and one algorithm for cohesive sediment. |

Process description
| Processes represented by model: | Bed boundary layer for pure current, combined current and waves, and pure waves. Transport of non-cohesive sediment. |
| Key physical parameters & equations: | The model uses hydrodynamics parameters, sediment characteristics (median grain size, density, possibly pre-existing bedforms), and water characteristics (viscosity and density computed from salinity and temperature) It uses Grant and Madsen (1986) continental shelf bottom boundary layer theory. Five methods to predict sediment transport for non-cohesive sediments are offered: Einstein-Brown (Brown, 1950), Yalin (1963) and Van Rijn (1993) Engelund and Hansen (1967) and Bagnold (1963). |

Additional comments
| Comments: | The computation routines can be accessed from different interfaces: a console program for batch-processing data from The computation routines can be accessed from different interfaces: a console program for batch-processing data from file or for interactively entering data, a graphic user interface for Microsoft Windows (especially useful for teaching or exploring the model), a Matlab MEX function to call Sedtrans05 directly from Matlab. The FORTRAN77 routines can also easily called from other programs. |
