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.

Dear, I am running the tutorial in f35 and get the error ERROR ! Time value 90000 not larger than previous time value 90000

I imagine a quick eye can probably explain to me what is wrong

lst file in attachement

Hello Mary,

Looks like you specify waste load data for identical time stamps. Have a look at block 6 in your input file to make sure all time stamps are different and increasing.

Let us know if that solves your issue.

It worked after changing the dates and restarting my pc. may be Figure 7.16 of the D_Water-quality User manual may be a bit misleading.
Thanks again
