流域の地形形態に関する定量的研究

Abstract

The statistical laws of geomorphologic properties in river basins, using the stream magnitude, are shown, postulating the topological randomness and the randomness of link lengths and theirassociated areas. The relations of various methods concerning channel classifications suggest-ed in the past, are statistically disclosed with the use of topological randomness and a new methodin terms of stream link order is proposed. The empirical laws of drainage composition basedon the stream order are theoretically obtained from the laws using the stream magnitude thatare proposed in this paper.
