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.

Hello everyone,

I am working with Delft3d in my master thesis. The thesis consists in the application of a hydrodynamic and water quality model for a Reservoir in Uruguay.

I could set up and calibrate the hydrodynamic module, but when I try to define the input for the Waq module I get this error:

waq_gui.exe Aplication Error

The application was unable to start correctly (0xc000007b).

it seems like it is a problem with the GUI. Can anyone help me?

Thank you in advance.

Agustin Rios.
