This study aims to characterize the morphology and contemporary floodplain deposit dynamics within a braided sandur system in upper Erdalen, a steep U-shaped valley in western Norway. Based on field observations, 2 different sub-systems can be identified within the braided sandur system : fine-grained to sandy flood sediments down-valley, and coarser, gravelly deposits in the upper part. A combination of different methods is applied for studying sediment dynamic processes within the braided sandur system (sedimentological and stratigraphic analyses, C 14 dating, dendrochronology and lichenometry). Results indicate that different sedimentary facies types are present and different phases of flooding can be identified
