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.

ABSTRACT
This work develops a real-time wave runup monitoring system and a method for predicting the height of wave runup and overtopping discharge on a seawall. The prediction was based on empirical formulas in the U.S. Army Coastal Engineering Manual (2011). The wave runup on the Tsen-Wen seawall in Tainan, Taiwan, was recorded during Utor, Usagi and Trami typhoons in 2013. To predict the height of wave runup and mean overtopping discharge in the subsequent three days, the slope and roughness of the seawall, the wave conditions and the water levels were required. Field measurement data were used to calibrate the empirical formulas. Agreement between the predictions and the in-situ measurement data reveal the feasibility of the proposed methods for monitoring and predicting the height of wave runup.
