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. 
On this discussion page you can post questions, research discussions or just share your experience about modelling coastal and/or estuarine systems with Delft3D FM.

Grazing of Phyto

Hi everyone,

I am having trouble setting a zooplankton compartment in ECO-BLOOM module. I guess I couldn't understand the concept behind "forced" zooplankton.

My goal is to set zooplankton so that they apply pressure term on phyto. So the questions are:

1) Modify preference, so that focused pressure is on phyto
2) Set different pressures on different phyto
3) What substances should be activated at least for a decent representation

I had a few trials setting the input concentration ranging from 0.005 to 1.
At every grid cell the model achieves those concentrations. So at the end there is a uniform picture. However, I do see changes such as chlfa levels respond. Yet I am not confident with what I have.

Any suggestions?
