Inadequate choice of parameters may result in either wrong results or failure of data analyses programs (calculation will be stopped by the executing program in a controlled way). In any case automatically calculated results shall be checked with respect to plausibility and consistence with underlying physical principles.<br /> <br /> The following informations are related to some of the most important parameters, especially if tidal characteristic numbers are going to be calculated. <br /> ==Choice of Master and Auxilary Reference Locations for Data Analysis==<br /> [http://www.baw.de/downloads/wasserbau/mathematische_verfahren/pre_postpr/pdf/refpos-lage.pdf Graphical representation] concerning the proper choice of master and auxilary locations for data analysis.
