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 WebHorton’s law of stream numbers is an empirical relation stating that the number of streams of order r decreases geometrically with r. Horton’s method partially needs information about spatial conﬁguration of the river network such as stream lengths and junction angles.

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. how to get the shura endingWebratio 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. john r fox

"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 ... " - Horton's law of stream numbers
