 note = {In order to pursue the desirable water environment, lots of works such as "nature-friendly river works" have been carried out so far. It is well-known that there are many factors related to the above-mentioned works. We have to elaborately take care of the water quality, landscape, space utilization, ecology, and so on along the river and riversides. In general, water quality has been estimated based on the chemical and biological viewpoints, even though comparison of both results is not necessarily done, sufficiently. For establishing how to estimate the water quality appropriately, both results will be compared to one another, and advantages of BI', one of the biological indices for water quality, will be emphasized., 長崎大学工学部研究報告 Vol.29(53) p.303-307, 1999},
