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.

how to use delwaq ViewerSelector?

Hi i`m herajet john, from in koea

in delft3d-flow,
if user use ViewerSelector, result data(velocity, ssc, etc..) analysis by example keyword.
ex) vs.exe
use trim-*.dat def trim-*.def

trim-*.dat : data
trim-*.def : data unit, information


So then in water quality, how to use ViewerSelector?

water quality output data (NO4, etc) in *.ada

Please answer if good example keyword..

HI herajet john,

Have you tried QuickPlot yet? It is much easier to read water quality output with that tool.

i know use quickplot post-processing but, i will make it easy systems

in linux system, user make shell script and one click system is so easy.

so, i should use vs program to setup one click system.

I'd like to know what you make of it.

Have you tried vsi.exe? This starts an interactive version of vs. Delwaq uses the same type of files (dat+def). When you made the selection you can 'save a batch' that uses vs to extract the data multiple times in the same way.

You can finde de delwaq substance names in the table SUBST_NAMES in the DELPAR_PARAMS section

Thanks for you great answer.


In my model,
Timeseries from hda file setting and automation one click system is complete. !!


But i can`t solved Another problem,

In my model, Flow sediment and water quality coupling equal time.
Grid is not execute aggregation and flow grid use water quality system.
coupling is *.hyd file.


Flow model output are added trim-file.
User connect trim-file from VSI.EXE, file structre m, n ,k.
So, user can seperate each time data or m,n data


waterquality all data file is added *.ada file.
user execute vsi.exe, can see array&data file name& each layer data.
But, flow model array is not equal water quality model.
How to solve this problem?


Can i know water quality file(*.ada) structure????

please good answer .
Always thanks..

Hi Hirajet John,

Results in de delwaq map file have no m,n,k structure, alle segments are in a single vector per time step. The numbereing is defined in the binary lga-file for the first layer. The numbering for the second and futher layer is equal to the first layer + (layernumber - 1) * number of segments per layer.
