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.

Sediment assigned to river discharge

Sediment assigned to river discharge

Good day! Is there any way to assign sediment discharge as part of river discharge locations? In Delft 3D Flow, is the only initial configuration of sediment concentration uniformly spread throughout the domain? Thank you for your consideration.

Hi Dianne,

In Delft3D you are allowed to specify sediment transport boundary conditions from all the open boundaries, to set the (spatial varying) initial condition at all the grid cells, to set discharge (in and out) of the computational domain using Operation/Discharge.

You may refer to Delft3D-FLOW Manual for boundary settings, section 9.4.2 for concepts. And 11.1.7 for more detail about boudnary and initial conditions. Or maybe you can register a Delft3D course, which will help you to deal with these complex issues within a short time.

Hope this is a little bit helpful,
