intro story Coast / Estuary

Coast / Estuary

Coastal 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 wave-induced 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.

Can anybody help me with information regrading morphology ? I need to know which version of Delft3D would be best and complete for any kind of morphological model. I'm using Delft 3.28 version. I'm not quite sure whether I would be able to define change in bed level in this version. I would be grateful if anyone can send me some sample file.

Thank you

Hi Ali,

Delft 3.28 version is capable to model sediment transport and morphology for sure. However you may be aware of that how good the model results all depends on how good the input is.

For the detailed input files, pls check the Delft3D-FLOW manual.

Dear Qinghua,

Thank you for your reply. I will have a look on the flow manual for our new morphology run.
