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.

Delft3D-Matlab to present wave and water level data

Hello,

I am looking to create maps of model outputs in Matlab, rather than using the GUI Quickplot. More specifically, I have wavm.dat outputs (e.g. HSIGN) and water level data that I would like to present over the model domain grid.

I am currently able to read water level and wave data from wavm.dat and trim.dat file in Matlab using the qpread. I have referred to the Delft3D-Matlab user manual, and this explains how to present bathymetry and data from the .grd and .dep file in Matlab (image shown attached), and X Y velocity, but no other variables.

I was wondering if anyone else had used the Delft3D Matlab files and functions (C:\...\delft3d_50\delft3d_ohmw_4.01.01.rc.03\delft3d\win32\delft3d_matlab) to create their own maps similar to the one attached but presenting wave and water level data, and had any suggestions or advice? Would you draw the model grid using 'wlgrid' and then (somehow?) present HSIGN or equivalent over the top? Or would qp_gridview be better?

Any suggestions would be great,

Thanks

Charlotte
