Abstract

A trial project for the improvement of seawater quality has been carried out in the New Nagasaki Fishery Port since the end of May 2001. 60 units of 3-dimensional asymmetrical bottom roughness with directional resistance properties were installed in order to enhance tidal residual currents around the existing breakwater, Before the installation of these bottom structures, field observations were carried out to identify the characteristics of the tidal currents, waves, water qualities and sediment from May 2000 to March 2001. These field observations on tidal currents and water qualities are summarized here.
