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.

Spurious concentration in dry/inactive cells

Spurious concentration in dry/inactive cells

Dear Delwaq modellers,

I am modelling using Zero values for concentration as initial condition in Delwaq. After a few time-steps I see high concentration in some cells, which are dry/inactive and in next time steps These concentration by flooding of These cells will affect the results. Could anyone tell me how can I tell to Delwaq to remover These inactive cells?I know that there is an Option in Windows GUI to do that, but for coupling using Linux there is no Option. I apperciate for yor answers in advance.
