  • A CASE STUDY ON A METHOD TO IMPROVE WATER QUALITY BY ‘<I>BOTTOM ROUGHNESS</I>’

抄録

Komatsu et al.(1997) have recently proposed a new water-purification method in a semi-enclosed coastal area. By means of this method, to activate the tidal exchange between the inner and outer sea area, installing many bottom structures “Bottom Roughness” controls a pattern of tidal residual current, which have an unsymmetrical 3-dimensional shape. In order to confirm the effect of the present method in an actual coastal area we started prototype test since May 2000 in New Nagasaki Fishery Port, Nagasaki, Japan. In this prototype test, 60 units of bottom roughness, whose height and width were 4m respectively, were installed on the bottom near two mouths of the port in May 2001. In this paper, some processes to apply this water-purification method to New Nagasaki Fishery Port were reported.
