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.

How to set transport conditions per cell

Youngling Posts: 16 Join Date: 1/15/19 Recent Posts


I want to set my transport conditions(salinity,temperature...) per cell at open boundaries instead of just begin-end form.

Like, I got 20 cells at the west boundary, and I want to set cell no.1-5 value 1, and cell no.6-10 value 2 and cell no.11-20 value 5.

Is there anyway that I can do this without changing boundary definition, Because I don't want to change the flow conditions as I was using the astronomical ones.
