Abstract
A tentative plan of Komatsu-city, in which people can live in symbiosis with a clear stream flowing near-nature channels has been proposed. The Kuryubashi river and the Furukawa river, both of which are at present heavily polluted drainnage channels, may be transformed into near-nature channels on the basis of the so-called ‘near-nature river construction method’. The resulting near-nature channel is composed of the open near-nature channel, in which only a clear stream flows, and underdrain channel, in which the polluted waste water, to be released from houses and factories is drained. The open near-nature channel will be constructed between two banks, and be divided into the high-water bank and sinuous low-water canal. A promenade will be prepared for the people's access on each the outer bank, while various aquatic plants will be planted within the channel.
