stream frequency

stream frequency

[′strēm ‚frē·kwən·sē]
(geology)
A measure of topographic texture expressed as the ratio of the number of streams in a drainage basin to the area of the basin. Also known as channel frequency.

Important areal, linear and relief parameters were computed such as perimeter, basin area, basin length, drainage density (Dd), stream frequency (Fs), elongation ratios (Re), bifurcation ratio (Rb), circulatory ratio (Rc) etc.
Stream frequency directs a positive relation with drainage density of the watershed proposing high stream population happens with respect to rise in the drainage density.
Parameter Formula Reference Drainage Density (Dd) Dd = [summation]L/A L Horton, 1932 = Length of the rivers; A = Area Stream Frequency (Df) Df = [summation]N/A N Horton, 1932 = Number of river segments A Drainage Texture (Dt) Dt = N[mu]/P N[mu] = Total Horton, 1945 number of stream in all segments; P = Basin perimeter
Elevated topographical conditions in the west initiated numerous small stream segments and it encourages greater concentration of stream frequency, drainage density and drainage texture.
Moreover, areal morphometric aspects like drainage density (D), stream frequency (Fs), texture ratio (T), elongation ratio (Re), circularity ra tio (Rc), form factor ratio (Rf) were worked out keeping in view the parameters outlined by Horton [5], and Pareta [24].
