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.

Crushing Delft3d-WAQ when entering data

I try to execute one of the WAQ Tutorials - Dispersion of E.Coli Bacteria. Delft3D-WAQ crushes when i change a properties of the discharge (changing to "Constant in time"). What is wrong?

I have tried it myself and no crash occurs - I have even tried it repeatedly.

Can you reproduce this? If so, can you tell us exactly what steps we should take to reproduce it?
