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.

Trachytopes BdfD50 question

Trachytopes BdfD50 question

Hi everyone,

I'm testing out Trachytopes in a simulation without sediments.
In the manual, it says that in this case one can specify a file (quickin produced I imagine) with varying D50 as input for the Trachytopes, using the BdfD50 keyword in the MDF.
But it does not say anything about its format or extension. What I have been using is the .d50 file I have, with varying D50 for the model area.
But, whenever the model starts, in the diagnosis file, it list all the Trachytopes related files it read but does not list my .d50. How can I know if he took the file under consideration for the run?
Is the file expected really a quickin format file, with any extension?

Any clarification on this would be much appreciated!

Regards,

Mihael Souza.
