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 QUASI-2D MODEL OF UNSTEADY FLOWS FOR River, lake, and reservoir ice PROCESSES
Author : YANG Kai-lin, GUO Xin-lei, WANG Tao, FU Hui and GUO Yong-xin
The development of the quasi-2D unsteady flow models for River, lake, and reservoir ice processes is one of the trends in the ice simulation field. The key idea of the algorithm is that the water level and flow along the flow direction are determined by the 1D unsteady flow model known as the St. Venant Equations and then the lateral velocity distribution within a cross section is calculated by the quasi-2D steady flow model. Based on the Ravier-Stokes model, the universal quasi-2D model for predicting the lateral velocity distribution within a cross section for prismatic channel under free flow and ice-covered flow conditions was presented. The formula of the local composite friction factor was given. The coupling method for 1D model and quasi-2D model
