Abstract : Some new methods for the topologic classification of channel networks are proposed. These methods are all based on the concept of topologic path length, or number of links from the network outlet to a junction or source. Two parameters, the total path length (sum of all path lengths) and the diameter (largest path length), are shown to be useful in network analysis. Some advantages of these parameters are that they are easy to measure, have straightforward topolotic interpretations, and are closely related to important geometric measures. Moreover, they are capable of explaining various empirical geomorphic laws', such as the 0.6 power relation between mainstream length and area. (Author)
