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.

Building damages due to mud flow on izu ohshima, japan in october, 2013
In Oct., 2013, typhoon no.1326 brought heavy rain, which exceeded totally 800mm and showed 120mm per hour, in Izu
Ohshima Then huge sediment disaster has occured in Motomachi area, located at west part of Izu Ohshima. In this study,
we clarfiy building damages due to sediment disaster. For this, we conducted field survey for bulding damage and
inundation depth in the above area and also performed numerical simulation of mud flow to examine the fluid force on
buildings. The results indicated that building damages in mountain and sea sides of the above area were caused by the
fluid force of mud flow and channel clogging due to sediment and driftwood, respectively. The range of building damages
in the sea-side area was limited 40- 60m from the Ookanazawa channel in the lateral direction. Such a narrow range of
the dameges corresponds to specific characteristics of sediment disaster. This shows a useful evacuation system for
sediment disaster.
