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.

Convert matlab file to a depth file

Hello,

I have some bathymetry data as a .mat file. I also have the data for the respective latitude, longitude coordinates. How do I convert it to a .dep file to use it as an input for a Delft3d model?

Thank you.

Hi A.D.

You should write it to an -ascii *.xyz file: aA three columns text file of x-coordinates, y coordinates and depth levels.
Subsuequently you can load this in Quickin, togther with your grid and interpolate it to the grid there.

Regards,

Emiel
