Abstract: River network characterizes not only water supply but also erosion and subsequent sediment transport by water flow within a catchment. Thus, understanding sediment cascades along river networks is the key for sustainable catchment management. Because tributaries compose major sediment sources within a catchment, sediment cascades of tributaries mainly operate processes of sediment delivery to the main stream. As some remarkable papers have suggested from viewpoint of downstream linkages of river networks, sediment cascades can differ among tributaries, reflecting spatial and temporal variations of hydrologic and geomorphic conditions within a catchment. However, researches quantitatively addressed differences in sediment cascades among tributaries and hydrogeomorphic thresholds of sediment delivery to the main stream are still limited. Here, based on examples from a headwater catchment in Hokkaido, we demonstrate geomorphic and rainfall thresholds of sediment delivery, which significantly differ sediment cascades of tributaries.
