Abstract: Experimental studies on artificial recharge of ground water were carried out for three years in Yamagata City, Japan. Two types of installation, pit and basin method were used for recharge. The origin of injected water for pit method was rain water on roof and that for basin was agricultural canal water during non-irrigation period. According to our estimation, about 2/3 of rain water on roof can be used. Annual input of rain water of 3.52 million m3 through pit and 225 thousand m3 through basin were obtained in experimented period of 228 days in 1986 to 1987.
