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 with Fourier output files

Youngling Posts: 5 Join Date: 5/12/15 Recent Posts

I haven't seen any post with this problem when using FLOW Fourier files output. I'm running a big grid flow model over the Pacific (2100*2600 nodes) with single batch or multi-threating batch mode. Trim and Trih files are fine but it looks like my water level in Fourier files is not computed well. Map outputs show shift in water levels.

I tested my Matlab function for plotting Fourier output files over a small grid size and it worked well. Here attached is the comparison between the 2 results plotting Fourier files.

Has anyone used max Fourier output files over big grids and had have similar problems ?

Thank you for your time, I will sincerely appreciate.
