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.

Delft-WAQ Coupling Error

Hi I am having this error come up when I couple my hydrodynamics to WAQ, and it is an error I am having when I try to create my WAQ boundaries later on in NESTWQ. Can you please help me? The error I am getting is Cannot convert string to directory? Is this also the reason why I am having issues when creating boundaries in NESTWQ where it says it cannot find the .coo and . lga files?

What program are you using for the coupling? Just from the error message my first guess would be that there is a space in the path name which is causing issues. My recommendation would be to always put your model files in a place with no spaces or special characters in the full path name and see if this helps.
