Hayagawa river - Japan (1)

  • Hayagawa river - Japan (1)

Hayagawa river, Yamanashi Prefecture, Japan in November 1998 - Looking upstream at the bed load material - The river is a tributary of the Fujigawa river, flowing at the foot of Mount Fuji. The Hayagawa is located on the Western slopes of the Fujigawa catchment. The photograph was taken upstream of the fully-silted reservoir of Nishiyawa dam (Japan, 1957): H = 39 m, L = 112 m, Res. Cap. = 2.38 Mm3, spillway cap.: 575 m3/s. The reservoir became fully-silted by gravel bed-load in less than 20 years. The reservoir was dredged in the 1990s down to 2 m to resume hydropower operation.
