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.

Pressure Distribution from Tsunami Bore Impact on a Cylindrical Structure
Author : Seyedreza Shafiei, Bruce W Melville, Asaad Y Shamseldin, Keith Adams and Sherif Beskhyroun
Tsunamis have recently become recognised as a devastating hazard of medium probability a nd potentially high risk for coastal communities in tsunami prone areas. Destructive tsunamis that have occurred in the last decade have stimulated an increase in the study of tsunami-structure interaction. This study investigates the tsunami bore impact on a cylindrical structure. Physical experiments were carried out in a large wave flume with a horizontal floor. Tests were conducted for a range of bore heights (110 mm to 155 mm), and bore velocities (2.19 m\s to 2.59 m\s). The vertical distribution of the applied pressure was measured using a vertical array of pressure sensors. The cylindrical structure was rotated so that the sensors were orientated at several angles between 0 and 135, giving in effect a three- dimensional pressure distribution around the structure. The flow-direction force was calculated by integrating the pressure over the projected area and was equivalent to a drag coefficient of 0.62.
