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. 
On this discussion page you can post questions, research discussions or just share your experience about modelling coastal and/or estuarine systems with Delft3D FM.

I study coupling system delft3d-flow, sediment, delwaq.

In delft3d-flow, user can withdrawal&return from discharge function.

In DELWAQ coupling system, can i use delft3d-flow withdrawal&return process???

How to application this function in delwaq system??

Please tell me good answer . :<

I'd like to know this function inlet-outlet for DELWAQ.
I've read the title "Automated Intake-Outlet coupling" and "E.9 Example source code delwaq_user_inlet_outlet" in User Manual.
But I don't know what I have to do.

Show me the example input files or model set, please.

If you define an inlet-outlet combination, you should be able to see that back automaticly in the WAQ user interface. In the inp-file, the locations will be named INLET01/OUTLET01, INLET02/OUTLET02 etc if you use multiple loactions. These will be recognised by the default user waste load pluging that you build with delwaq. Look into the waq_plugin_wasteload project in Visual Studio, or into \src\engines_gpl\waq\packages\waq_plugin_wasteload\src\delwaq_user_wasteloads.f.

By default WAQ will also look for the existence of a file named inloutl.dat, in which you could optionally specify other names to be coupled inlet outlets in a fixed format 2 times 20 character list: '(2a20)'.
