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.

Domain Water Level Error

Hello all,

I'm trying to simulate hydrodynamics in a port located at the southeast brazilian coast. I set up a circular mesh and in the boundaries I set WL (tidal harmonics) in the east boundary and Neumann in the south and north boundaries. However the model crashes at the beginning (around 1% of the simulation) and when I check my results the WL is very irregular, mainly inside the port (I'm sending attached a snapshot of the WL). I have checked the boundaries, the bathymetry and time step, but I can't figure out what is the error.

Someone faced similar error? Any tips?

Thanks in advance,

Hi Leonardo,

Did you find an answer? I am doing something similar, if you haven't solved your problem, attach your files, I might help.
If you find an answer, please comment it.

Good day
