| Outline of Final Research Achievements |
Aquatic biota in the agricultural drainage channel continues to fluctuate for almost a decade after the improvement work with concrete-lining, where not loss of the biomass, but the change of the constituent species is seen. Installed eco-friendly works show certain effectiveness to maintain the fish ecosystem and the fluctuation of each species mainly depends on its spawning style. Remarkable self-purification of water due to denitrification and some mechanism is confirmed. Thus, conservation of the ecosystems and purification of the water can be considered as a part of the function of drainage channels. Finally, a scenario based model that is built by the acquired knowledge shows the ecosystem in the channel might be very vulnerable even to the slight change in its environment.
