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.

Hydraulic Characteristic Study of the Geo-synthetic Materials Protecting Embankment Downstream Slope Under the Exceeding Standard Flood
Author : Guoxiang Xuan, Chenjun Zeng, Xiaogang Wang, Yun Li and Long Zhu
Because of the frequently extreme climate, embankments break at times under the condition of exceeding standard flood. In this paper, a method of protecting embankment downstream slope by using geo-synthetic materials is presented based on the mechanism of dam breach. Experiments are carried out for the hydraulic characteristics of flow over three kinds of geo-synthetic materials. The resistances of geo-synthetic materials against flow are studied in detail. According to the hydraulic model tests, the rules of distribution of water depth, velocity and shear stress over geo-synthetic materials along the dam slope are gotten with different heights of overtopping. Meanwhile, the friction coefficients of the three geo-synthetic materials are obtained. Furthermore, the mechanical characteristics of each geo-synthetic, which serves as shielding materials for slope protection, are analyzed. The results show that all the three kinds of geo-synthetics can be used to slope protection. The geo-synthetic materials of 2 300g\m have the priority according to the mechanical characteristics.
