The aim of this study is to clarify residents' opinion on a river. The residents were asked to answer the questionnaire which required their free description. The answers were examined with neiborfood method for cluster analysis.The results indicate that:1 . People who live around the upstream of the river, where has been developed recently as a residensial area and has problems with its congested traffic, would be happier if the river was an underdrain.2. People who live around the midstream, where flooded several times in the past, want the city administration to take flood preventive measures.3. People who live around the downstream, where its water quality hasn't improved significantly, hope that they would have a clearer stream.In addition, comparing these results with our last survey, which used multiple-choice answers only, it is proved that free description is effective to reveal unexpected results for reseachers, such as the one described above as #2.
