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. 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.

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 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.
