To solve this problem, selective intake facilities were constructed at the Asahi Dam and the Takane No.1 Dam. Using these facilities, coupled with power plant operation at 4 dams in the Hida River, the persistent turbidity has been gradually decreasing. 1. Outline of the Project The Hida River is the Kiso River System’s largest tributary with a total watercourse length of 134km and a total catchment area of 2,177m 2 that originates in Mt. Norikura and Mt. Ontake located in the southernmost part of the North Japan Alps and flows southward meeting many tributaries including the Akigami and Maze Rivers to finally join the Kiso river in Mino Kamo City (Fig.-1). Many power source development projects have been conducted in the Hida river basin since long ago, and currently the total number of power stations and the total of the permitted/approved maximum outputs are 23 and approximately 1.14 million kW, respectively (Table-1). -

Muko City, Kyoto
Muko city, Kyoto 1 Section 1 Nature and(Geographical Environment and Weather) 1. Geographical Environment Muko city is located at the southwest part of the Kyoto Basin. Traveling the Yodo River upward from the Osaka Bay through the narrow area between Mt. Tenno, the famous warfield of Battle of Yamazaki that determined the future of this country, and Mt. Otoko, the home of Iwashimizu Hachimangu Shrine, one of the three major hachimangu shrines in Japan, the city sits where three rivers of the Katsura, the Uji and the Kizu merge and form the Yodo River. On west, Kyoto Nishiyama Mountain Range including Mt. Oshio lays and the Katsura River runs on our east. We share three boundaries with Kyoto city - the northern and western boundaries with Nishikyo-ku, and the eastern boundary with Minami-ku and Fushimi-ku. Across the southern boundary is Nagaokakyo city abutting Oyamazaki-cho which is the neighbor of Osaka Prefecture. The city is approximiately 2km from east to west and approximiately 4km from south to north covering the 7.72km2 area. This makes us the third smallest city in Japan after Warabi city and Komae city. Figure 1-1-1 Location of Muko city (Right figure (Kyoto map) : The place of red is Muko city) (Lower figure (Japan map) : The place of red is Kyoto) N W E S 1 Geographically, it is a flatland with the northwestern part higher and the southwestern part lower. This divides the city coverage into three distinctive parts of the hilly area in the west formed by the Osaka Geo Group which is believed to be cumulated several tens of thousands to several million years ago, the terrace in the center, and the alluvial plain in the east formed by the Katsura River and the Obata River. -
Geomorphological Evolution and Sediment Budget Analysis with the Uji River, Kyoto
D-7 Fourth International Conference on Scour and Erosion 2008 GEOMORPHOLOGICAL EVOLUTION AND SEDIMENT BUDGET ANALYSIS WITH THE UJI RIVER, KYOTO Ryoukei AZUMA1 and Hideo SEKIGUCHI2 1Member of ISSMGE, Assistant Professor, Disaster Prevention Research Institute, Kyoto University (Shimomisu, Yoko-oji, Fushimi-ku, Kyoto 612-8235, Japan) E-mail:[email protected] 2 Member of ISSMGE, Professor, Disaster Prevention Research Institute, Kyoto University (Shimomisu, Yoko-oji, Fushimi-ku, Kyoto 612-8235, Japan) E-mail:[email protected] This paper starts with presenting field evidences that illustrate the occurrence of significant bank erosion in a reach of the Uji River. It then demonstrates that the resulting escarpment was not a mere local adjustment, but is an indicator as to how extensively the Uji River has undergone appreciable amounts of channel erosion over the entire 15.2km-long section. The datasets on which the discussion is based include: the cross-channel topographical data (200m intervals along the river course) in 1967, 1979 and 2006 made available from the Yodogawa Office, MLIT. A careful geomorphological analysis of the datasets in terms of GIS, permitted the determination of tempo-spatial changes of areal sediment storage in the Uji River. When integrated over the entire river course, the overall volume of sediment loss due to erosion proved to amount to 3.1 ×106 m3 in the period from 1967 up to 2006. A discussion is made to identifying its practical implications for future riverine management. Furthermore, a discussion is made of the linkage between the extent of the channel erosion and the depositional environments of the sediment that constitutes the boundary of the river channel. -

International Hydrological Programme International Hydrological Programme Forest Hydrology Conservation of Forest, Soil, and Water Resource The Twenty-fourth IHP Training Course 24 November - 7 December, 2014 Nagoya, Japan Hydrospheric Atmospheric Research Center, Nagoya University Supported by Water Resources Research Center, Disaster Prevention Research Institute, Kyoto University Outline A short training course “Forest Hydrology Conservation of Forest, Soil, and Water Resource” will be programmed for participants from Asia-Pacific regions as a part of Japanese contribution to the International Hydrological Program (IHP). The course is composed of a series of lectures and practice sessions. Objectives Incident rainwater is firstly intercepted by foliage and branches and evaporates from their surface to the atmosphere. From the surface full of rainwater, the rainwater conducts to soils along the plant body, and also, some of incident rainwater directly reaches the soils without touching foliage and branches. These rainwaters coming to the soils infiltrate into the soils with being influenced by the soil pore structure, and reaching to groundwater table. During the slow soil water movement, some of the soil water is absorbed by plant roots. It conducts through stem conduits, reaches leaves, and evaporates to the atmosphere through stomata. The ground water flows to a river. This is an outline of water cycling in the forest ecosystems, and science on this water cycling is “Forest Hydrology”. As one can see above, Forest Hydrology has two major scientific aspects, i.e., discharge from forested watershed and water use by trees (evaporation from the forest canopy). Soils in the forested watershed have a high hydraulic conductivity at the ground surface, which prevents from soil erosion, and functions to make soil water flow slow, resulting in a behavior like a dam. -
