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.

Concentration values - Transport Condition

Hej everyone,

I started running my model and tested some different setups concerning the sediment concentration.

In the FLOW GUI within Boundaries - Edit Transport conditions/.bcc - file, the default setup provides to add the Begin-Sediment concentration and the End-concentration is set to 1.
I also checked what happend if I add the same value as for strat/begin and lightly different results concerning the sediement concentration occuring.

Do you have experiences concerning the right/most senseful setup?

Thanks for your help,
