Abstract : The paper describes a model of drainage basin composition that is primarily based on two postulates suggested by investigations of the role of randomness in drainage network development. The postulates are: (1) the topology of channel networks is random; (2) link lengths are independent random variables drawn from a common distribution. A third postulate, introduced to explain areal properties, is that the dimensionless parameter K studied by Melton and Shreve is approximately unity. Examples of the appplication of the random model in description, estimation, and explanation of drainage basin properties are given. (Author)
