This study provides an analysis of local flow hydraulics, and their spatial variations and relationships with erosional and depositional landforms. The study area is located in the Columbia River Gorge where the multiple flood pathways of the channelled scabland converge into a single path. The results of step-backwater calculations allow the preliminary assessment of energy conditions associated with erosion and deposition features. Despite the multiple outbursts which occurred during the late Pleistocene, only a few of them had the required magnitude to overcome the threshold conditions and accomplish significant geomorphic work
