Analysis of channel asymmetry: A different perspective

Abstract

An attempt to measure channel asymmetry of a cross-sectional area of a river was perhaps taken first by Knighton (Quant Indices’ Earth Surf Process Landf, 6:581–588, 1981). But his effort did not match his presumptions of keeping the index value within a fixed limit of 0 to 1, especially in his A 1 and A 2 measures. To overcome this and another genetic problem of those indices, this chapter presents alternative measures viz. A w, A a, and Awa to the end. For the purpose, simple measures of trigonometry and mensuration, have been employed.
