| Research Abstract |
This research project developed a network-type model for river environmental management, in which hierarchical accumulation structure of the stream network was introduced using the stream orderings. The network model for stream temperature was used to examine the effects of the impact of human activity and climate change on the river environment. In Ibo River basin, a test basin of this study, the results of the network model indicated that the heat balance in stream in summer was dominated by the heat flux on the water surface, whereas in winter significance was formed by the heat transport from ground water on the riverbed. As for the effects of climate change, the model analyzed the stream temperature changes due to changes in air temperature and precipitation, indicating that temperature rise in the upstream seems to be larger than that in the downstream of the river basin.
