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.

Parameters not found in inp file and empty *.par file

Parameters not found in inp file and empty *.par file

I'm using TELEMAC input files to drive DELWAQ.  We get the following message in the inp file 

; 'SURF' - has missing value or model not suited
; 'bottomdept' - has missing value or model not suited

In a  2D example we can get around this by deleting these lines and replacing:
; 0 - number of parameters
with ; 2 - number of parameters
 ; parameters in binary file

BINARY_FILE 'run-name.par'  ; binary file

Where 'run-name.par' would be the file produced on saving/creating the inp file.

This changes matches what I have had before in earlier version of DELWAQ and from a test using Delft3d flow inputs. In a 3D case , we get the same message, but the fix doesn't work as the *.par is empty, and we get a file reading error in WAQ-2.
The main  issue  is that the *.par is empty, as well as the inp file is not processed properly from TELEMAC input files 

Any help/advice gratefully received
