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. 
On this discussion page you can post questions, research discussions or just share your experience about modelling coastal and/or estuarine systems with Delft3D FM.

Error with SedDia key

Error with SedDia key

Dear guys,

I've a problem with the SedDia key
I read in the forum that I should write (for example):

SedDia = #diameter.d50# [m] Median sediment diameter (D50)

I generated the diameter.d50 file using Quickin to generate a *.dep file and I've chenged the file extension to *.d50 as you specified (it works when I generate different erosion thickness). Nevertheless I cannot load such a file and the error: "Error reading file...." appears.
(I tried without ## but no way)

Please, may you help me?

Thank you
