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.

Non-hydrostatic solver and mpi-simulation

Was non-hydrostatic solver implemented in parallel? When I tried to run it on multiple nodes I got the error message. If there is any workarounds possible to solve it?

Thanks,
Dmitry

Hi Dmitry,

The functionality that is supported/unsupported in parallel is listed at https://svn.oss.deltares.nl/repos/delft3d/trunk/src/engines_gpl/flow2d3d/doc/parallel_status.txt

Z layer model is listed as unsupported functionality unfortunately. Someone from Deltares might be able to advise if there are any plans to implement it soon or if there is a workaround?

Cheers,

Richard

Hi Richard,

Thank you for your message. I've recently enjoyed running Z-model in parallel so I guess I can't wait to take advantage of all it's functionality emoticon

Look forward to hearing about new capabilities and workarounds.

Regards,

Dmitry
