Description :
This study quantifies geomorphic characteristics of 23 gravel-bedded, forest stream reaches grouped into 2 categories: 1) undisturbed, and 2) heavily impacted by timber harvesting and associated road building (disturbed). Disturbed reaches are located within the area of immediate disturbance. The AA. develop an objective methodology for the assessment of channel condition based on measured geomorphic variables. Data are analysed using multivariate statistical techniques in order to produce discriminant functions for the classification of streams as either disturbed or undisturbed.
