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.

coupling flow and part modules
Answer (Unmark)
8/25/15 2:44 PM
I am trying to couple flow and part modules. Here is my flow setup for the storage communication file:
- interval 1 min (flow has time step 0.05 min)
- start time 1 hr (flow has start time 0 hr)
- stop time 6 hr (flow has stop time 6 hr)

The flow ran successfully and generated the com- file for the coupling. When I try to run the coupling program, I get the following error message. Can anyone suggest what might be wrong in my flow or coupling set up? Thanks

Could you solve your problem? I am having the same issue.

Yes, I believe the PART code is checking the number of discharge locations. Even if you have zero discharge location, you MUST add a dummy one, say at cell (2,2) with discharge zero for your simulation duration. This should not change anything on your hydrodynamic responses. BUT the PART module will not complain anymore.

How did you solve your problem?

I am also experiencing error 6005 in the coupling.

Thank you.

I did a test with and without DISCHARGE and verified that the coupling only works if you put at least one DISCHARGE avoid the error:

NEFIS message 6005: Element 'MNKSRC' does not exist in definition file

I tested with a WAQ (inlet) tutorial.
