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.

Bathymetry Data File in DELFT-Dashboard

Bathymetry Data File in DELFT-Dashboard

Thanks a lot for your advice.

I used RGFGRID and QUICKIN to generate the "XXX.grd", "XXX.enc", and "XXX.dep" files. But, these files can't "show" in DELFT-Dashboard window. But, these files, if generated in DELFT-Dashboard, can "show" in DELFT3D-FLOW module. Why?

Hi Leon,

What is the coordinate system you are using when you generate this grid in RGFGRID? Is it cartesian?

Hi Renan:

Yes, I am using cartesian for all models.

Did you change the Coordinate System at Delft Dashboard?

tab Coordinate System>Select UTM zone

Hi Renan:

You are right. After changing the coordinate system to select UTM zone, the grid and water depth show in Dashboard.

Thanks a lot for your advice.
