利用高分辨率分布式水文模型和A1 B气候变化情景下模拟的MRI-AM 20 km投影输出，研究了日本Tone River流域未来河流流量的变化。多个大坝水库的运作和目前的用水信息也被认为是现实的河流流量模拟。假设未来用水量及水库运作与现时情况相同。分析结果表明，与流域上游地区相比，流域下游的河流流量变化似乎微不足道，但预计未来缺水天数会更频繁，特别是在Tone-Ozeki站。除非未来当前用水需求发生适当变化，否则应编制修订后的坝库运行规则。
Future river flow changes in the Tone River basin, Japan, were investigated using a fine resolution distributed hydrologic model and the MRI-AM20km projection output, which is simulated under the A1B climate change scenario. Multiple dam reservoir operations and current water usage information were also considered for realistic river flow simulations. The future water usage and reservoir operation was assumed to be the same as under current conditions. Analysis results show that the river flow change downstream of the basin seems to be insignificant compared to the area upstream of the basin; however, more frequent water shortage days are expected in the future, especially at the Tone-Ozeki station. Revised dam reservoir operation rules should be prepared unless the current water demand changes properly in the future.
