INTRODUCTION


The INTERCOH conference series initiated by Prof. A. J. Mehta has provided a forum for engineers, scientists and ecologists to exchange and share knowledge, information and experiences on encountered problems and effective measures to be applied relative to cohesive sediment transport.

The behavior of cohesive sediments having electrostatic charges is complicated and often gives rise to significant environmental problems. Cohesive sediment particles adsorb organic and/or inorganic matter, nutrients and heavy metal etc., and thereby play a key role as contaminant carriers.

This meeting in Saga is the 8th International Conference on Cohesive Sediment Transport (INTERCOH 2005), and its role has been expanded to emphasize the environment as a whole, over and beyond the nearshore and estuarine zones. The 2005 conference will focus in particular on environmental impacts and related aspects of cohesive sediments.

A noticeable change in the benthic habitat during the past decade in the Gulf of Ariakehas become a matter of great public concern, because it has resulted in the degradation of water quality and the benthic sedimentary environment. Tidal flats are most important to the coastal ecosystem, and Ariake Bay occupies almost 40% of tidal flats in Japan. As a result, INTERCOH 2005 in Saga has attracted a great deal of attention in Japan.
