Horton's law of stream numbers
WebSep 12, 2024 · stream. It was observed that the number of streams gradually decreases as the ordering of the streams increases. This is in accordance with the Horton’s law of stream numbers (Horton, 1945). Stream length The total length of individual stream segments of each order is the stream length of that order. Totally, 131.61 km stream length 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].

WebFor example, underlying distributions which are exponential and gamma distributed, while not power-law scaling, produce power laws in the tail probabilities when rescaled and sampled according to Horton's law of stream numbers. The power-law exponent is given by the expression phi=ln(R(b))/ln(R(A)), where R(b) is the bifurcation ratio and R(A ... WebHORTON’S LAW OF STREAM NUMBERS 59 channel networks” will be defined here as networks in which the mergers among streams of equal order are controlled by chance …
Webratio Sr+',n/Sr,n, and Theorem 2.2 states the property of the number of branches Sr+ '%n. The limit variance 4r~3 in Theorem 2.1 becomes large as r increases, whereas the limit variance in Theorem 2.2 becomes small as r increases. From Theorem 2. 1 , the following property, which can be regarded as Horton's law of stream numbers, is easily derived. WebMost customary explanations for Horton's metric laws of stream lengths and drainage areas are based on the idea that in river nets one can speak of cycles or generations of rivers. However, this customary explanation presupposes certain topological features in river basins that do not seem to occur in nature.
WebFig 16.5 shows the Strahler method of channel ordering. The number of stream channels of each order is expressed by a mathematical relation, known as Horton's law of channel numbers, in which the number of stream channels of each order forms an inverse geometric sequence with order number,

This law was chosen for define the term hereticWebtopological 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.

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.)
