Kamabuchi Experimental Watershed
Summary
- The Kamabuchi Experimental Watershed is located in the northern part of Yamagata Prefecture, in the head water area of the secondary tributary of the Sake river which flows into the midstream of Mamuro river, a tributary of the Mogami River.
- Hydrological observations were started in order to elucidate the relationship between forest cover and water runoff in a snowy cold region.
- Observations began in 1939 at two watersheds called the No. 1 with 3.060 ha and the No. 2 with 2.482 ha.
- Observations began in 1961 at another two watersheds named No. 3 with 1.540 ha and No. 4 with 1.117 ha.
- Observation of all watersheds within the Kamabuchi Experimental Watershed is continuing today, although observations at No. 4 were temporally halted at 2000.
