. "This article indicates the quantification tools, with whose assistance it is possible to characterize the morphology (shape) of the valley network and determine their variability caused by the scale change. The monitored characteristics (quantification tools) are: 1) %22number of various order valleys %22 according to the Gravelius order system; 2) %22valley networks' density%22; 3) %22bifurcation ratio of various order valleys%22; 4) %22total length of various order valleys%22; 5) %22total length-order ratio of various order valleys%22; 6) %22average length of various order valleys%22; 7) %22average length-order ratio of various order valleys%22; 8) %22fractal dimension of various order valleys%22; 9) %22relative fractal dimension of various order valleys%22; 10) %22valley junction angles%22; 11) %22homogeneity of various order valleys%22. These characteristics have been applied to the paradigmatic examples of the schematic valley networks according to Howard (1967) and have been analyzed in three scales. In order to analyze the valley networks, the most suitable are %22valley junction angles%22 and %22homogeneity of various order valleys%22, i.e. the quantification characteristics resistant to any increase in the scale, %22number of various order valleys%22 and %22total length of various order valleys%22, where the relevant values dropped while increasing the scale, but the normal (Gauss) distribution of values was preserved." .
