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.

Experimental study on influence of levee breach depth on flood wave propagation in inundation area
Author : Kwang Seok Yoon
The present study was carried out to investigate the propagation characteristics of the flood wave in an inundation area due to levee breach depth. For study, a propagation distance, a propagation velocity, variations of the water level and variations of the maximum depth were measured. As a result of measurement, around the levee breach point, the propagation velocity is mainly depending on the levee breach depth. However, the general trends have the similarity with a special condition that the levee breach depth is 0 (H0=Hw). On the basis of measurements, coefficients k and m were calculated which were suggested by Toshiji Ariga (1977). In addition, an empirical formula which has the highest coefficient of determination was suggested using correlation analysis of dimensionless variables. The suggested formula was derived under a limited condition that the inundation area is flat and it is made of cement mortar. The empirical formula could be used as an important fundamental data for a feasibility study of experiments.
