| Outline of Final Research Achievements |
Yamato River, which origins Kasagi Mountain district in Nara Prefecture, flows into Osaka bay is well known as dirty river in Japan, whereas many people swam in the river until 1960 era. Population growth attached to city development during high economic growth period and development of industries caused rapid degradation of water quality in 1970 era, whereas the water quality was improved because of sewage improvement recently. About 15 km distance from the mouth of a river, Yamato River was shifted in Edo Period, and consequently most of the channel of this reach was straight.
We focused on the main channel of Yamato River and tributary of the Yamato River; Tomio River to clarify macroinvertebrate assemblages and process after disturbance.
