Abstract: We have investigated ecological roles of instream features such as riffle-pool sequences and gravel bars indiverse river channels, especially from the empirical perspectives of habitat diversity and organic matter interactions. We compiled a series of field-based studies undertaken in diverse conditions of river channels in three countries, and found that instream riffles and gravel bars in rivers should be massive natural filters for self-purification and for primary energy resources to the river ecosystem by retaining organic matters.
