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.

Diatoms and Non-Diatoms

Hello everyone,
I am using the Delft3D Water Quality model. In the Processes section, I defined the WAQ module and, in this module, I selected the Algae group for study (where I included the substances Diatoms and Non-Diatoms).
Here we have inputs and outputs of Diatoms and Non-Diatoms in gC/m3. These units refer to the biomass of phytoplankton, right? But the amount of carbon is related to the percentage of carbon in the molecules or the amount of total carbon?
Also, if I want to use only chlorophyll inputs can I do it too?
Thanks in advance.
