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 statistical output function STAPRC

Error with statistical output function STAPRC

Hello, I´m trying to use the STAPRC statistical output function without success. In the list file appears the following

“ERROR no critical level specified for percentage”

The input file I´m using includes the two variables the User Manual indicates for this function: THRESH and ABOVE. I can´t figure out what the “percentage” related to this error is.
In case anyone has experience with this function, I copy beneath the tenth block of my input file for some help. Thank you!

; Tenth input block

period 'prueba'
suffix '1d'
start-time '2015/02/01-00:00:00'
stop-time '2015/02/02-00:00:00'

output-operation 'STAPRC'
substance 'EColi'
suffix 'Uso III'
real-parameter 'THRESH' 1000
logical-parameter 'ABOVE' 'yes'

I checked the code of this statistical calculation where the error message stems from, and it seams that the manual is wrong on the name of the required parameter. It is not named THRESH but CCRIT for this statistic. I guess it was copied erroneously from the 'geometric mean' which uses a THRESH parameter. I hope you can get it running now with CCRIT.


P.S. I've corrected the manuals on this. It should be published in draft tomorrow on this site (at under: Latest draft documents

Thank you Michelle, it works correctly using the parameter CCRIT
