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.

A 3D Numerical Simulation of Nanjing Sanchahe River Gate Project
Author : Cheng Zeng, Yingping Zang, Lingling Wang, Yubao Wo, Xiaopeng Xue and Yang Xiao
The Nanjing Sanchahe river gate project, which locates at the Qinhuai River estuary, is an important part of the comprehensive environmental treatment of Qinhuai River. In order to accurately reveal the hydrodynamic characteristics and flow pattern of the water flow behind the sluice gates under the typical water retaining conditions with sluice gates closed and water flows over the gates, a closed equation system based on the Reynolds averaged equations and RNG k-e turbulence equations is developed to conduct the three dimensional numerical simulations of the flow patterns under the typical water retaining conditions. The computed results agree well with the measurements of physical experiments. The flow pattern, the vortex structure and the velocity distribution behind the sluice gates are predicted and analyzed. The present research contributes to a better understanding of the safe operation and structural stability of the Sanchahe river gate project.
