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.

How to get temperature from FLOW in WAQ?

How to get temperature from FLOW in WAQ?

Hi,

I'm trying to run WAQ coupled with FLOW.
However, I can't figure out how to setup WAQ to get temperature data from FLOW.

I tried to model using water temperature process and without this process.
With water temperature processes I think it is possible to WAQ model temperature or user have to give all the temperature related data.
In the second case, it seems WAQ is using a constant temperature.
I made off-line coupling.

Can anyone help me?

Hi Julio,

You have to include the coupling file from flow *.tem as a segment function. At the end of your Delwaq inp file you will find these lines: The .vdf should already be there...add another one below for temperature....Then you should see 'Temperature_Flow' in your output map files.

; 0 - number of functions
SEG_FUNCTIONS
'VertDisper' ; name of segment function
ALL
BINARY_FILE '/p/folder/name/filename.vdf' ; binary file
SEG_FUNCTIONS
'Temperature_Flow' ; name of segment function
ALL
BINARY_FILE '/p/folder/name/filename.tem' ; binary file

good luck,

Katherine

Thanks a lot, Katherine!

I just had to add some additional steps regarding configuring processes in PCLT and it worked fine!!

The steps were:
- I haven't used water temperature at general tab.
- I made the temperature constant and editable
