In order to examine a water environmental improvement, human sense data on the water environment is very important criteria. However, human sense on the water environment has not been discussed in detail. This study examined the feature of human sense on dirtiness, color and smell of the water environment and the relation between human sense data and physical behaviors which are tide, rain situation and seasonal change. This study area is Hori River which flows in Nagoya City. The time and area on the worst condition are obtained with the time-space distribution of the human sense data on dirtiness, color and smell. Moreover, the difference of human sense between dirtiness and smell is shown clearly. Finally, the human sense models are developed with the Hayashi’s quantification methods. The validity of models, the difference of analysis results between dirtiness and smell, and future subjects are shown by comparison forecasting human sense data and questioner results.
