摘要

本研究以位于爱知县和岐阜县的八个水头(井山、明治友井、森松原、关川、古瑞草、翁游、细川和冈岛)为例，利用溢流流量估算其发电潜力，并厘清其发电特点，以评估小型水力发电厂的可行性。结果如下:首先，溢流排放比水头来水排放更稳定，表明溢流发电更适合实际发电。其次，在放电利用率为60%的情况下，最大输出功率为43千瓦至2,002千瓦，显示出这八个水头的发电潜力。最后，由于灌溉和降水季节变化对取水量的影响，月发电量波动大于年发电量波动。

Potential for and feasibility of small hydropower generation at headworks in Japan

: In this research, power generation potential is estimated using overflow discharge for eight headworks (Inuyama, Meiji-yousui, Muromatsubara, Kansakawa, Furikusa, Onyu, Hosokawa and Okajima) located in Aichi and Gifu Prefectures, and the characteristics of their power genera‐ tion are clarified in order to evaluate the feasibility of small hydropower plants. The results are as follows. Firstly, over‐ flow discharge is more stable than the discharge of intake water at the headworks, which suggests that power genera‐ tion using overflow discharge is more suitable for actual power generation. Secondly, maximum power outputs of 43 kW to 2,002 kW, under a discharge utilization factor of 60%, show great potential for power generation at these eight headworks. Finally, fluctuations in monthly power generation are higher than that of annual power generation due to the influences of irrigation and seasonal changes in precipitation on water intake.

期刊介绍： Hydrological Research Letters (HRL) is an international and trans-disciplinary electronic online journal published jointly by Japan Society of Hydrology and Water Resources (JSHWR), Japanese Association of Groundwater Hydrology (JAGH), Japanese Association of Hydrological Sciences (JAHS), and Japanese Society of Physical Hydrology (JSPH), aiming at rapid exchange and outgoing of information in these fields. The purpose is to disseminate original research findings and develop debates on a wide range of investigations on hydrology and water resources to researchers, students and the public. It also publishes reviews of various fields on hydrology and water resources and other information of interest to scientists to encourage communication and utilization of the published results. The editors welcome contributions from authors throughout the world. The decision on acceptance of a submitted manuscript is made by the journal editors on the basis of suitability of subject matter to the scope of the journal, originality of the contribution, potential impacts on societies and scientific merit. Manuscripts submitted to HRL may cover all aspects of hydrology and water resources, including research on physical and biological sciences, engineering, and social and political sciences from the aspects of hydrology and water resources.
