Horton's law of stream numbers
WebJan 4, 2010 · Two basically different models have been proposed in order to give a rational explanation of Horton's law of stream numbers: the “cyclic” model and the “random graph” model. WebThe paper presents tables of calculations of the expected stream lengths and drainage areas of Strahler streams of various orders for networks with various numbers of first order streams, based on… Expand 6 Drainage Basins and Large Scale Landscape Development A.

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. 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 states that "the numbers of streams of different orders in a given drainage basin tend closely to approxi-mate an inverse geometric series in which the first term is unity and the ratio is the bifurcation ratio" (Horton, 1945, p. 291; see also 1932, p. 356). This law was chosen for

Web8. Horton’s Laws of Drainage Composition . Law of Stream Numbers . The Law of Stream Numbers relates the number of streams of any order (i) to the bifurcation ration (R b) and the principal order (k) in the basin. k i N R i b = −. where k is the highest order stream, i is the ith order stream and R b is the bifurcation ratio.
