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.

Vegetation Decomposition Parameters

Vegetation Decomposition Parameters

Youngling Posts: 9 Join Date: 4/10/11 Recent Posts
I am looking for typical values for some parameter in vegetation module, as:
mortality rate and stoichiometric ratios for decomposition of drowned vegetation in reservoir and lakes.

I don't know for example if default parameters are in the magnitude order of these parameters,
Someone already worked with this issue has some literature recommendation on this subject?

Thanks!

Hi Julio.

You will find defaulft values for those parameters in the Water quality user manual.

Furhtermore, I recommend the following literature (tropical climate):

- http://oss.deltares.nl/c/document_library/get_file?groupId=183920&folderId=247778&name=2001

Ines do Vale.

The GHG report from Deltares was very useful for me.

Thank you very much!

Dear Ines,

Is it possible that you can share the last two documents? I can not found the document on the given website.

My email address is xiawei@nus.nscc.sg

Best,
Xia Wei.
