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.

Grid error in Wave

I made the attached grid, and every things seems fine in flow, but when I try to open it import it in the wave GUI, I get an error message that says, "Invalid Grid File"

Then if I open up the Visualization Area I can see my grid, but many of the points seem to be connected to one point far off to the south. I'm not sure if this is related to the problem, but I felt that it was worth mentioning. I have attached the grid and enclosure files.

Hi Ryan,

Have you tried to change missing value to 0 (instead of -9.99....E+02)?
That often solves the problem.

Where exactly can I change the missing value of the grid file?
