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.

Delft3D-Wave space varying boundary conditions in spherical coordinates

Delft3D-Wave space varying boundary conditions in spherical coordinates

Padawan Posts: 25 Join Date: 3/25/12 Recent Posts

I am using Delft3D wave and I would like to set space varying boundary conditions along a boundary. I adopted a spherical coordinate system. How can I impose the distance from corners in order to vary the boundary conditions in space? Should I impose a distance in degrees or in meters?

Managed to solve the problem. If I use a spherical grid the conditions along a boundary must be specified with distances in degrees.

Hi Francesco Enrile,

Sure!  Thanks for sharing this as well!
