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: Binary/unformatted file does not have the correct size

I finding the following error while runing the preprocessor for delwaq:


Input comes from binary file: Q1.par                                                                                                                                                                                                                                                          
 ERROR: Binary/unformatted file does not have the correct size: Q1.par                                                                                                                                                                                                                                                          
        The size should not be zero and it should be a whole multiple of 982764 (= 4*(1+2*122845))
 ERROR reading the data block !
 ERROR encountered in processing this input item !

 ERROR. Reading block   7 !! Check input file !!

 ERROR. Too many and/or invalid data in block   7 !! Check input file !!



The only strange issues i found in block 7 are this mesages:

; 'ACTIVE_EMERSION' - has missing value or model not suited
; 'Zthreshold' - has missing value or model not suited
; 'MaxIterations' - has missing value or model not suited


In the manual it says these commands are related do z-model conversion, but i'm usig regular sigma layers. I'm not sure how to fix it.


if anyone has a clue I would be grateful.
