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.

Temperature Simulation under FLOW - Heat Flux Model

Dear Delft3D Community,

My current research work focuses on sea surface temperature simulation within coastal area. However, here is a burning question that I have encountered and it would be great if you could give any suggestions:

Under the Delft3D - Heat Flux Model, if I use a 2-D simulation rather than a 3-D one, will the resulting temperatures be "surface temperatures" or "depth-average temperatures"?

I look forward to learning your ideas, and thank you very much in advance for however you may help with!

Best regards,

Hi Angang,

They will be depth averaged values,

In the Temperature Excess Model (heat flow model 3), what is the value of the natural background temperature?
Could you use the temperature of a weather station?

Thank you very much.
