A comment on Horton

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. Strahler reﬁned Horton’s method so that the WebApr 15, 2015 · Robert E. 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 … WebAccording to Horton (1945, p. 291), “the numbers of streams of different orders in a given drainage basin tend to closely approximate an inverse geometric series in which the first term is unity and the ratio is the bifurcation ratio.” This “Law of Stream Numbers,” which describes an observed regularity in nature but does not bwr intranet

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.

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.
