Hydrological observation reports of the Kamabuchi Experimental Watershed —No. 1, No. 2, No. 3 experimental watersheds— (January 2006 through December 2010)

Abstract

The Kamabuchi Experimental Watershed (KEW) is located in the snowy cold region of Mamurogawa Town, Mogami-gun, Yamagata prefecture, and has been observing since 1939 to clarify the water resource storage function of forests. The current KEW is covered with a mixed forest of coniferous and broadleaf trees such Cryptomeria japonica, Chamaecyparis obtuse, Fagus crenata and Quercus serrata. In this report, an overview of the topography, vegetation and forest operation history of the Nos. 1, 2 and 3 watersheds of the KEW are shown, and the maintenance works of the forest-watershed experiment are introduced. In addition, this report shows daily runoff at each watershed, and daily precipitation and snow depth at Yamagata Experimental Forest adjacent to the KEW from January on 2006 through December on 2010.
