Abstract

The link slope distribution for given magnitude links from 18 basins in the Appalachian Plateau changes from a left skewed, to a normal, to a right skewed distribution resembling a log normal distribution as the average stream gradient decreases. Variations in the link slope distribution can be partly explained by the decrease in the tendency of streams to move downward with a change in available relief or distance and by the effects of local geologic and geomorphic conditions prevailing in a basin. Downstream interior link slopes vary with magnitude following a power function. Their scatter about the log of the power function is constant in most basins. Based on these elementary properties of link slopes and the probability of occurrence of links of any one magnitude, a general model representing the distribution and expectation of interior link slopes for an entire channel network is formulated. The observed interior link slope distributions for different basins vary in shape from a monotonic decrease in frequencies with increasing stream gradient to a unimodal and sometimes bimodal distribution when exterior links are included. In spite of the large changes in the shape of the histograms for different basins, the theoretical distributions provide a good reproduction of the data.
