Horton's law of stream numbers
WebHorton's law of stream numbers at all, or not with the same bifurcation ratio as the main basin. Such an example is given in Figure 1. A test of a given network for structural Hor-tonianness has been given by the writer [Schei degger, 19676]. CYCLIC MODELS Although Horton only coimted stream num bers, Horton's law has generally been taken as Webbifurcation ratio Rb is the base. This law has been found to be (statistically) valid also if the slightly modified stream ordering procedure proposed by Strahler (1957) is employed. (See for a discussion Scheidegger, 1968a.) Horton's law of stream numbers, in its original form, is only a statement about certain

WebHorton [1945] found that the decrease in number and in- crease in mean length of streams with centripetal order is approximately geometric and hypothesized that the increase in mean subbasin area is also geometric, as confirmed by Schumm [1956]. WebTwo fundamental laws connect the numbers and lengths of streams of different orders in a drainage basin: (1) The law of stream numbers. This expresses the relation between the number of streams of a given order and the stream order in terms of an inverse geometric series, of which the bifurcation ratio r b is the base.
WebA) Law of Stream Numbers and Bifurcation Ratio: The linear regression analysis returns a slope m = -0.40682. Thus, RB = 2.551635.

Horton coined these four laws: the law of stream numbers, the law of stream lengths, the limits of infiltration capacity, and the runoff-detention-storage … Webtopological law. Horton's [1945] topological law is expressed in terms of the bifurcation ratio R t, dye' where r•N•o is the stream number of order o• in a basin of order 12. Horton proposed that a constant value of Rt, is approached asymptotically as order increases in homogeneous catchments.
