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.

Flood and evacuation simulations considering the risk of evacuation route
In this study, water-related risks of the disaster with respect to the evacuation route are evaluated. Walking evacuation safety is considered in the case of flood and inundation in Kashima City, Saga Prefecture, Japan using flood and evacuation simulations. The simulation performed the plural patterns that changed in inflow point. The computed results show that water depth in the northern part of the city increased, whereas flow velocities in the eastern part of the city were high. This result insists that the evacuation route to the shelter was not always safe. In the evacuation simulation, many residents could not reach to the present shelters. Due to many roads inundated, there are residents who cannot evacuate to the nearest shelter. Moreover, it was examined where the safe shelter exist. They are existing sometimes on the way the residents must pass through the dangerous routes. These results show that the shelters should be put considering the topographical characteristics and the risk of the evacuation route.
