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.

water level problem near the bank

hello,
i have an issue with Delft3D Flow because when I display the water level with Quickplot there are some discontinuity near the channel banks. The water level on the low-lying land doesn't reach the zero value (the same height of the land).
the time stem respect the Courant formula and there aren't vegetation of sediments
please help me.

Thank you very much

Hi Alessandro,

Can you post a figure to explain your description on "some discontinuity near the channel banks"?

Best Regards,

Qinghua
