Description :
Field study of bedrock step-pool systems along the upper reaches of Soda Creek shows strong correlation between several form variables (shape) and channel slope. Although step height and step length showed no regular spacing and variable correlation with channel slope, length to height ratios demonstrated strong negative correlations. Correlations between step height to length ratios and channel slope varied between 3 lithologies (basalt, andesite, dacite). The frequency of pool shape classes did not vary by lithology, but specific shape classes developed under differing slope conditions by rock type.
