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.

Sedimentation adsorbed Cr (Sed_Cr)

Hi,

I'm trying to activate the "Sedimentation adsorbed Cr (Sed_Cr)" process, however, the following message is displayed: 

PARTMP: Kinetic sorption for Chromium not implemented!
 Stopped with error code :           1

Can someone help me?
Thanks.

The error message is quite clear: slow or kinetic sorption is not implemented for this metal. You will have to rely instead on equilibrium sorption. That is in general the recommended way. In this case use the total concentration and not the separate adsorbed and dissolved concentrations. These are available as output.

Thanks, Arjen. I did what you suggested and it worked.
