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.

License Expired & program error

Hi all
I have two questions. first, My license was expired. I sent a request for a new license and I have not replied. I s anyone faced the same problem and what is the advice? second, I added a new settling velocity question in the program by modifying the subroutine (settling_velocity.f90 )when i run the program it gave me this error message " unable to alloc 64 bytes". anyone saw this error before?
Best regards,

Hi Aisha,

I forwarded your license problem.

Can you attach your changed subroutine "settling_velocity.f90" to a post at this forum?

Thanks.

Regards,

Adri

Dear Adri
Thank you very much for your reply. I attached the subroutine file.
Attachments: SEDIMENT DATA_S.sed (1.7k), settling_velocity.f90 (8.0k)

Hi Aisha,

These files don't look strange.
Further investigation is needed. I mailed you a set of questions.

Regards,

Adri
