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.

Wave height limited for coastal WAVE model

Wave height limited for coastal WAVE model

Youngling Posts: 2 Join Date: 3/9/20 Recent Posts
Hello everyone,
I am running a FLOW-WAVE coupled model to determine wave heights at a coastal region with the use of time varying but spatially constant wind parameters. The results obtained do not match those of a buoy in the same area. the wave height modeled seems to be limited at both peaks (wave height doesn't seem to increase beyond 2.5m or reduce below 1.5m).
Is there any limiting factor that's preventing my wave height from increasing?
Any advice or help on this is greatly appreciated. I have attached some of my trials and results for more information.
