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.

d3d_qp error to read Delwaq-results

Dear Markus,
I used the "multiple copy" feature of Delwaq to include the fractions of IMs. Delwaq1 and 2 are run successfully but using Matlab-Toolbox to read results (d3d_qp) does not work for fractions, however it works for all other substances like continuity. The error after selecting the fractions, for example IM1; fraction1, is :
"Caught in qp_getdata/griddata:
Dot indexing is not supported for variables of this type.
In private\d3d_waqfil>getsize at line 1860
In private\d3d_waqfil at line 228
In qp_getdata>hvslice at line 531
In qp_getdata at line 423
In private\qp_plot at line 71
In d3d_qp>d3d_qp_core at line 1970
In d3d_qp at line 44"
 Could you tell me the reason and how can I solve this error?
Many thanks,

Hi Dear Markus,
I found the solution. The normal .ada and .hda files do not work, but using map-file and some tricks the problem was solved.
Thanks again,
