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.

Bedload sediment transport

Dear,

I am a new user of DELWAQ. I was wondering If it is possible to simulate bed load transport of sediments, If possible, How can I define the necessary data in the input file.
If someone could provide some tips or exaples would be nice.

Regards,
Marcelo

Hi Marcelo,

Well, I’m sorry to say that bed load transport of sediments is not available in Delwaq. You would have to use the morphology module if Delft3D FLOW for that.

best regards,
Michel
