| Research Abstract |
The interaction between physical and ecological phenomena of benthic habitats in some gravel rivers with lower disturbances is discussed by combining the results of some field investigations and laboratory experiments. The following sub themes compose the present study, (1) the differences in bed material composition and these biological effects, (2) "bio-consolidation" due to the inhabitation of aquatic organisms, and (3) the interaction between physical and ecological phenomena of benthic habitats. The each of topics is conducted to relate the effects of catchment characteristics and dam construction.
