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.

Problematic tsunami generation - initial wave (Delft Dashboard)

Youngling Posts: 1 Join Date: 5/9/19 Recent Posts

Dear all,

I'm facing a problem with the generation of the initial tsunami wave as my initial conditions file (.ini) is consists of zero values only (see attached photo).

Although the model setup and the final step of tsunami computation (illustrated by an initial wave figure) seem to work correctly, the matrix of the .ini file is empty.

Last week, I downloaded again the Delft Dashboard but the problem persists.

Does anyone have an idea of how to solve it?

Many thanks,

Debbie
