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.

An Investigation into Woody Debris Trapped by Riparian Trees during the Yabe River Flood in Japan
Author : Muhammad Islamy Rusyda, Kensuke Sakada, Sinya Ikematsu and Haruyuki Hashimoto
A large amount of woody debris was trapped by riparian trees of the Yabe River during the 2012 flood. Two types of woody debris jams can be found; one is the accumulation formed by a single tree or utility pole and the other is the accumulation by two or more different trees. Approximately 40 % of the 68 longest pieces of jams had a length from 2 m to 4 m and about 70 % of the 68 longest pieces had a diameter less than 0.1 m. The horizontal scale of jams increases significantly with the length of the longest piece except the region of their smaller values. The depth of jams was smaller than the maximum inundation depth. The horizontal scale of jams was nearly equal to horizontal scale of obstacles in the case of two or more different trees as obstacles. Finally, the dependence of volume of woody debris jam on the shaded area A of obstacles is clearly shown. o
