Hydrogeomorphology: overview of an emerging science

Here, we introduce a series of 14 papers generated from a symposium related to hydrogeomorphology that was part of the Fifth International Conference on Geomorphology. Additionally, recent developments in hydrogeomorphology are highlighted, particularly with respect to research in Japan. Linkages are drawn between natural hazards and the necessity to focus on hydrogeomorphic processes. Future research needs are discussed in the areas of temporal and spatial patterns of water and sediment dynamics, including the effects of distributed land management practices and interactions with natural hazards.
