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.

DELWAQ MAXIMUM GRID NUMBER(MAX CELL)?

HI, BECOME A DELWAQ USER.

IN SPITE OF READ MANUAL, MODEL SETUP & APPLICATION IS NOT EASY FOR ME. '_'..

I HAVE ANY QUESTION FOR DELWAQ MODELING.

IN CASE OF ANOTHER MODEL(EX. efdc.. etc), IT IS ALREADY DETERMINED MAX GRID_NUMBER(EX. X,Y,Z).

HOW ABOUT THIS MODEL?

X,Y,Z IS DETERMINED FOR USED DELFT3D GUI?

PLEASE TELL ME.

THANKS YOU.

Hi Hrejet,

The dimensions of your WAQ domain are initially determined by the the FLOW (hydrodynamic) simulation. With the coupling between FLOW and WAQ you can then aggregate your dimensions in the horizontal, in the vertical or in time.

If you are using the hydrodynamic results (FLOW) from somebody else you can discuss with them how to best change their domain without incurring into excessive numerical diffusion or make changes that are not reasonable in terms of hydrodynamics.

If you want to start from scratch you have to learn how to use Delft3D-FLOW first if you don't know that already.

Regards,

João.
