Abstract

In this research, public opinion on the projects was collected by a questionnaire including the questions on availability of the related information; important factors for river;the desired river, bank protection, and flood plain; and personal behavior with environmental consideration. The collected answeres indicated that the information on river improvement projects was not entirely spread to the public, and both the flood control and natural environment were considered important regardless of expense of the projects, and the projects wcrc not per ceived by the public as close as the other enivironmental problems.
