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.

Question For Delft3D-Flow

Question For Delft3D-Flow

Youngling Posts: 2 Join Date: 1/7/15 Recent Posts
Hello, Guys~

My name is Wonhyun Lee, now I am interested in Cyclone model, but I have a big question for that.

In particular, for the evaporation and precipitation rate.

well, normally, Delft3D-Flow provides the XXX.eva (additional parameter : Fileva ;#XXX.eva#) files to apply it.

However,

I would like to apply the spatial-temporal varying evaporation and precipitation rates into the model.
For example, if the cyclone is moving and landfalling to some area,
normally lots of rainfalls is accompanied with a hurricane.

So, could you please let me know, 'spatial-temporal varying evaporation & precipitation rates are available for Flow model?
or
any tips for input files (evaporation and precipitation rates)
or is there any option that evaporation & precipitation rates are included with a hurricane?

Have a great day.
Wonhyun
