The Chikugo plain located in the southern part of Fukuoka Prefecture is prosperous in agriculture. In this region, there are a lot of creeks in various sizes, and it used to be closely related to its community. But, as modernization progresses, environmental problems such as water pollution and disruption of ecosystem have been emerging. By a land consolidation project or an irrigation and drainage project that started from 1970, water ways with straight lines and concrete banks were built. It made agriculture more efficient, but the environment problems in creeks progressed and consequently living areas for aquatic creatures have decreased. But in recent years, the creeks and irrigation systems have reached the end of their life, and the traditional functions of creeks are reconsidered. A base of farming, disaster prevention, environmental preservation, a place of recreation, and design of scenery are desired as functions in creeks. In the survey for citizen in neighboring area, they desire most of the above functions for future creeks, and especially the function of environmental preservation. And we hope that massive functions of recreation or scenery provided by re-construction of creeks help towns more animated. In this research, on-the-spot investigation and the survey for citizen in neighboring area are conducted to understand present problems and improvement desired especially about banks in the creeks, and consequently to find out ideal creeks.
