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.

Tide Data Input

Youngling Posts: 11 Join Date: 3/13/13 Recent Posts
Hi,

I'm a masters student in Water Resources Development at BUET, Bangladesh. I'm using Delft3D over the Bay of Bengal using the Tidal level generated from tide harmonics.

Now I've to input almost 7000 tidal data in the boundary which would be so cumbersome If I put them manually.
Can anybody help me that I could input them in easier and quicker way ?

Thank you
PS

Hello. Your post is quite old so you've probably sorted this already, but just in case: You could run your boundaries using the harmonic constituents rather than time series. This is the nicest solution, since you can then run your model for any time frame. Otherwise, you can make your .bct boundary time-series file offline in excel or something like that.
