The general principles, as recommended by a number of authors, e.g., Woynarowich and Horváth
(1980); Pecha, Berka and Kouril (1983) and others, are that in every specific case the existing
conditions and circumstances should always be considered and that the guide parameters should be
adjusted on the basis of preliminary trials.
