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.

Elliptical Grid
Answer (Unmark)

Hello,

I was wondering if it is possible to create elliptical grids in RGFGRID. I am able to create circular grids with hollow centers, but I want to make an elliptical grid instead. Is this possible in this software?

Attached is an example of something I want to make (except with a hollow center and no barrier islands). Basically, I want to make an elliptical grid around an island with only the center of the island not inside the grid.

Thanks,
Yahia
