Abstract
It has been thought that flood control is important to improve rivers; however, this often adversely impacts the ecology of the river and water quality. Recently, the importance of preserving the natural environment and waterscape amenity has been linked to improving the riverside. Changing the banks of rivers, however, can lead to many problems with residents who live there.
In this study, we studied the behavior of school children and their parents along the Murasaki river in Kitakyushu city. The authors gave out a survey in 1999 to 1350 residents who live along this river. A quantification theory (III) was conducted and the results indicated these residents want riverside improvements that are particularly relevant for children. The authors also discussed possible future improvements for the Murasaki river.
