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. 
On this discussion page you can post questions, research discussions or just share your experience about modelling coastal and/or estuarine systems with Delft3D FM.

Extract flow paths (streamlines?) using MATLAB or QUICKPLOT

Extract flow paths (streamlines?) using MATLAB or QUICKPLOT

I have run a hydrodynamic model for a treatment pond (about 90X183 sq m) and obtained velocity vectors and magnitude. Now I want to trace the flow paths (different possible paths for a water drop from inlet to outlet), and if possible get the velocity magnitudes along these paths. Can you help me please? I have been struggling with this for some time now, any help is appreciated.

Hi. I've not tried it, but Muppet is downloadable from this site and should do be able to do this.
