| Outline of Final Research Achievements |
This study was conducted above and below a run-of-river hydropower weirs and plants with particular references to their reducing / releasing waters, in order to clarify the effects of a series of water intake structures on the nutrient dynamics in mountainous river system.
The Odum's concept of stream metabolism was adopted with the dissolved oxygen concentrations and the other water environmental variables such as water levels, temperatures and electric conductivities in combined with simultaneous practical investigations of attached algae, fish community and river water.
According to the results, gross production (P), community respiration (R) and their ratio could be evaluated at each of the conditions. It also could be suggested the cumulative effects of the series of water intake structures with the degeneration of P and R variables in correspondences with the dissolved nutrient concentration, the algal and fish community structures, respectively.
