2 For Rich Living of People Outline of KIZU-River Basin Outline of YODO (KIZU) River Basin YODO River Basin includes six prefectures, MIE, SHIGA, KYOTO, OSAKA, HYOGO and NARA. Upsteam of the River is divided into UJI-River, KIZU-River and KATSURA-River. YODO-River flows to OSAKA bay 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 INA-River 4.6% Downstream of YODO-River 9.8% Lake BIWA 46.7% River KATSURA-River 13.4% KIZU-River 19.4% 8,240km UJI-River 6.1% Catchment area and Length of rivers Lake BIWA UJI-River KIZU-River NABARI-River Others KATSURA-River Downstream of YODO INA-River TOTAL Catchement Area Length of River (km) 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. Domestice water supply plan by reservoirs Domestic water supply area Area / OSAKA pref.

4 For Effective Management Outline of KIZU-River Basin Outline of Integrated reservoir management office KIZU-River Integrated Management Office has managed five reservoirs on upstearm of KIZU-River effeciency and effectively for water resources management. And integrated office have roles as a core office to comunicate with related agency for management.

5 Telecommunication System for Integrated Management Outline of Telecommunication System KIZU-River Integrated Management Office has communication line with not only five reservoirs but also YODO-River Integrated 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. Telephone line and Network Legend Radar, (Rainfall observation) Telemer (Water Level, Rainfall data) Optical Fiber Cable (Monitoriing Video 4

7 Data and Information Management for Interated Management It is necessary for 5 reservoirs integrated management to observe and collect hydrological data(river Water Level, Rainfall, data) on Real-Time. We manage the information and data through telecommunication control facility for 24 hours.
