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.

Theory on mud / fine sediment processes and modeling

Hello all,

Recently we have had some questions about how to use Delft3D for modelling fine sediment (or mud). Often people do not know that you can use Delft3D not only for e.g. morphological studies, but also for typical fine sediment related issues like harbour siltation, (dredge) plume dispersion, water quality etc.

Since the processes involved in mud (modeling) are relatively complex, we uploaded two Powerpoint presentations by dr. Bas van Maren (Deltares/ Delft University) on the Community Wiki. You can find them via 'Wiki' in the top bar of this page, and then go to 'Background theory cohesive-fine sediment-mud'). One presentation is about mud processes in general, the other focusses specifically on numerical modeling.

We hope these presentations will give you some more insight in the important processes and how to use Delft3D to model them!

Happy modeling!
Arnold

PS: soon we will also add some mud-related tutorial to the Wiki!
