KIZU-River Integrated Reservoir Management Office For Rich Living of People Outline of KIZU-River Basin ●Outline of YODO (KIZU) River Basin Basin includes six prefectures, MIE, SHIGA, , , HYOGO and NARA. Upsteam of the River is divided into -River, KIZU-River and KATSURA-River. YODO-River flows to after confluence of these 3 rivers at south-east of KYOTO. Headwaters of KIZU-River is from SUZUKA and NUNOBIKI mountain rage. KIZU-River meets NABARI- River at OKAWARA after through mountanous vally and UENO area. KIZU-River meets WAZUKA-River at KAMO after confluence of NUNOME-River at KASAGI. Finaly, KIZU-River reaches to confluence point of three rivers at south-east of KYOTO. KIZU-River is 1st class river (management by Natinal Governemnt), Catchment area is 1,596km2. It occupy 21.9% of total catchment area of YODO-River. On KIZU-River basin, TAKAYAMA Dam, SYORENJI Dam, MURO Dam, NUNOME Dam and HINACHI Dan was constructed, these dams have reduced flood and storm risk and suppied water for drinking, industry and agriculture. NABARI-River flows from TAKAMI mountain range. NABARI-River is 1st class river, catchment area is 615km2. Basin includes three prefectures, KYOTO, NARA and MIE

Ratio of YODO-River Catchment area Catchment area and Length of rivers INA-River 4.6% Downstream of YODO-River Catchement Length of River River 9.8% 46.7% Area (km) Lake BIWA KATSURA-River UJI-River 13.4% 8,240km KIZU-River NABARI-River Others KATSURA-River KIZU-River Downstream of YODO 19.4% INA-River UJI-River 6.1% TOTAL

●Water Supply Development of water resources by reservoirs dams had been implemented for increase of water demands for domestic and industry during and after high economic growth period (1960s). And, we supply irrigation water for agriculture filed along NABRI-River and KIZU- River from reservoirs.

●Outline of Telecommunication System KIZU-River Integrated Reservoir Management Office has communication line with not only five reservoirs but also YODO-River Integrated Reservoir Management Office, KIZU upstream River Management office and Japan Water Agency Headquators and Kansai Regional Office. These communication lines are consist of strong radio signal that is stable against disaster. we manage reservoirs effectively and effeciency with collecting hydorological data (Water Level, Rainfall, etc) for water supply and flood control.

4 5 Data and Information Management for Interated Reservoir Management

It is necessary for 5 reservoirs integrated management to observe and collect hydrological data(River Water Level, Rainfall, Reservoir data) on Real-Time. We manage the information and data through telecommunication control facility for 24 hours. TAKAYAMA, SYORENJI, MURO, NUNOME, HINACHI
