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.

Problem in 3D model result

Youngling Posts: 9 Join Date: 7/27/18 Recent Posts
Hi,I am trying to run a storm surge scenario. My model is a tide forced online wave coupled model including wind file as a .spw file in the additional parameter section. The model runs successfully in 2D and produces the reseaonable result.
The problem is when I add 3 layers for the 3D model setup, the simulation completes successfully without any error and generates trim and trih file. But, the result files do not show any result. I also checked with the Matlab code. I found that all the simulation result is NaN or 0.
However, time to complete the simulation and the sizes of result files are normal. For example, the trim file size is around 28GB and time to finish the simulation is 14 hours. There is no error in tri-diag files. 
Anyone experiences this kind of issue before? Any kind of suggestion/help will be highly appreciated.
Kind regards,Wasif
