IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

Water Temperature Effects of Benthic Invertebrates in The Natori River Basin
Author : Ryosuke Arai, Kei Nukazawa, So Kazama and Yasuhiro Takemon
We conducted the quantitative samplings of benthic communities and measurements of water temperature in the headwater streams of the Natori River basin once a month in 2011 and 2012. As results, the Sorensen similarity index decreased significantly with the water temperature difference 2 expanding (R =0.11, p<0.001). The population densities of Plecoptera decreased significantly with the 2 water temperature rising (R =0.12, p<0.01). The average population density of Plecoptera shows 2 significant negative correlations with maximum water temperatures (R =0.92, p<0.001).
