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.

Add-on sediment will not be activated

Dear all,

Some warnings are remindered when I verifying my input files in Flow module: " Add-on sediment will not be activated." & "DPUOPT set to MEAN".

I'm not sure if these warnings are related to the situation that when I add sediment consitution in [FLOW-define input-Processes], a dialog box pops up saying that "Depth at velocity point set to 'Mor'!". Or if anyone have some idea about the problem, please favor me you instruction.

Thank you very much!

Best regards
