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.

2D spectra time series

2D spectra time series

Youngling Posts: 2 Join Date: 4/23/13 Recent Posts
Hello,

I'm trying to run delft3d WAVES in a "non-stationary" with 2D spectrum files of a time series.
The problem is that my spc2 output files are always with the same value.

I'm don't know how I do to couple the 2D spectrum files with the time frames.
I tried to do in two ways: one with a Geral.bnd file, that contains all my 2D spectra time series and another with my hourly time series separately by files for each hour, but I don't how to force the model with that information.

Could anyone explain to me?

Also, I'm trying to use the spectrum file on the boundary (I have 3 boundaries). I inserted the lines as I read here in the community
[Boundary]
Name = Boundary1
Definition = fromsp2file
OverallSpecfile = Geral.bnd

But, to inform that I have three boundaries I need to use in this way

[Boundary]
Name = Boundary1
Definition = fromsp2file
OverallSpecfile = Geral.bnd
Name = Boundary2
Definition = fromsp2file
OverallSpecfile = Geral.bnd
Name = Boundary3
Definition = fromsp2file
OverallSpecfile = Geral.bnd

taking off the [Boundary] keyword of the others boundaries (2 and 3). I don't know if this is the right way and if the model is understanding what I really need, but with the [Boundary] keyword, an error appears.

Attached are all my files that I'm trying to run. I just sent two hours of the separated hourly files.

Any help?? I really appreciate.
Fernando
