The purpose of this study is to clarify the value of a river, as a recreational space for inhabitants. We carried out the observation survey and the interview with users in Seno River located in the east area of Hiroshima City. These investigations were conducted in five seasons from summer of 1994 to summer of 1995. Based on the calculated number of the people playing in the river, we compared among the effects of the time zone, weekdays or holidays and four seasons. Also, characteristics of each recreational use were shown. For example, playing with water is not frequent, but staying time is long. On the contrary, walking is daily and customary, but staying time is short. Lastly, to clarify the effects of the physical settings on uses, we analyzed by the Quantity Theory Cluster I. As the results of them, we showed that weirs and bridges give opportunities of playing with water.
