Statistical report of hydrological data from TAKARAGAWA experimental watershed.-HONRYU and SHOZAWA watershed (January, 1991 to December, 2000) -

Abstract

The Takaragawa Experimental Watershed is located in Minakami in Gunma prefecture (36°51' N and 39°01' E). The experimental watershed was established by the Kanto Forest Management Bureau in 1937 for the purpose of examining the effects of artificial development of the Okutone Natural Forest on runoff from a mountainous area. Observations of precipitation and runoff have been conducted since the inception of the experimental watershed. Observation data from 1937 through 1990 have been published in several reports. This report builds upon earlier reports by describing daily precipitation and runoff from 1991 through 2000.
