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.

Issue with rotating grid administration

Issue with rotating grid administration

Youngling Posts: 2 Join Date: 7/5/16 Recent Posts

I'm currently having an issue with changing my grid administration for my model. Basically, I have a rectangular grid created with RGFGRID, and as per the default, the M and N coordinates begin from the bottom left corner of the grid. I need to change it so that the M and N coordinates begin from the top left of the grid. This is because my land boundary is to be located south of the grid.

My issue is, there seems to be no response from the grid administration when I click "rotate grid administration".

I'm not sure if I am missing something obvious as there are no similiar threads regarding this issue posted here.

The RGFGRID version I am using is, and I have attached the grid file for you to take a look at.

I just tried rotating your grid file and had no issues using RGFGRID (I (1) imported the grid then (2) turned on mesh administration node numbers under the view menu so I could see the orientation, then (3) rotated the grid three times to get node 1,1 into the top left hand corner).

Not sure what is causing it not to work for you? Maybe someone with the same GUI version as you can test it to see if a bug has crept into RGFGRID
