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.

question regarding wavecon.rid file

Dear Deltares,

In the wave model of Delft3d, Wavewatch3 modeled data was used to generate a wavecon.rid file according to the format required by the manual. after running the model, the result doesn't really make sense, it shows the significant wave height all zero. it seems that the wavecon file has not been read and process by the model, but the manual suggest that 'To use the Wavecon option, just simply add the < Wavecon.rid> file to the working directory and the system will use the file automatically' Is there something that need to pay attention to make the wavecon file work?

Thanks!

Hi Jun,

maybe, you should check these messages in order to review your WAVE setup:

Even, I would recommend you to check out the Emiel's files shared in his post.

Regards.

Hi Jun,

If you have problems with the wavecon file, you also should try to use bcw file.
I prefer to use bcw file because as Qinghua said, this file is more versatil approach.
In order to find out which the best way is to use a wave time series, using WAVE, I did a test
with both options: wavecon vs *.bcw, and it's true... bcw file is more versatil approach.
My simulations, using a bcw file finished most quickly than with a wavecon file.

Thanks. that is really helpful!
My additional question is, when I ran the wave alone model with Delft3D, I didn't find any GUI place for me to put in the reference time. since the wavecon file has a physical time in the first column, where can I specify the reference time point ?

Hi Jun,

It is true that you will not find out in the GUI the way to give your time points, directly.
You should use a text editor in order to made your mdw files or if you are using the GUI,
first you need to create your mdw file and later, with a text editor, you should modify the
file and then, you add the time points.

Even, I strongly recommend you that you use a text editor to create all your mdw or mdf fles.
The first times is a little confuse, because you need to review the manuals,
but later when you understand the syntax, formats, parameters,etc... the input process of Delft3d is easy.

Kind regards.

Gabriel.
