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.

Hello,

What is the procedure to insert the same border the following data:
Tide (FES2004) and Water Level Model (Mercator French)?

Did the following:

Executed the experiment. Appears only in the results data Water Level (Time Series). You need to activate any function to which the data from the Water Level of Mercator and forcing the Tide (FES2004)?

thank you

Hi Luis,

I'm not aware that you can have both Z and Astronomic type of boundaries together in the same segment.
If this is a new feature please ignore the rest of my reply.

When I have to add water levels from wind/mesoscale to tides from harmonics this is what I learned with the CSIR people in Stellenbosch:
1. Build a small 3x3 grid with say 10m cells at the same latitude you have your model.
2. Run this grid with 100m constant depth and all of the viscosity parameters of your "real" model for the time you want your boundary forcing.
3. Extract the water levels from the history files at the central point (choose your dt but at least 1h is advisable).
4. Add your extra water level (from the mercator) to those results.
5. Force this last water level as a A boundary type in the "real" model.

Hope it helps,

João.
