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.

Possible bug in RGFGRID after entering "Edit Grid" mode

Possible bug in RGFGRID after entering "Edit Grid" mode

My name is Anton and I have only recently started using Delft 3D for my work. 


In RGFGRID if I have entered the "Edit Grid" mode I am not able to enter either "Edit Spline" or "Edit Polygon", see attachments for a screenshot before entering "Edit Grid" mode and after entering "Edit Grid". 

I am sorry if this has already been answered or if this is the intended behaviour but from chapter 5.2 in the manual it doesn't appear to be intended. I would be very grateful if anyone could help me shed some light on this behaviour. :)

I am running on Windows 10 Pro 64 bit.


Maybe there is something obvious that I am missing. :)
