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.

Numerical Simulation of Flow and Upstream Fish Movement inside a Pool-and-Weir Fishway
Author : Shokry Abdelaziz, Minh Duc Bui, Namihira Atsushi and Peter Rutschmann
Analysis of the fish movements in real situations is a good way to understand the dependence of fish behavior on the hydraulic conditions. This paper presents a numerical model to study the path of fish movements at different hydraulic conditions. The commercial computational fluid dynamic code FLOW-3D was used to simulate the fish ladder flow. Based on the results of the flow simulation,a numerical model for fish movement was developed by combining a low energy concept and random movements in which the effects of turbulence and fish memory are taken into account. The model was validated using experimental data of flow and fish movement inside a pool-and-weir fishway archived from a previous study (Atsushi, 2009). The simulated results of the flow velocity and the fish path are in good agreement with the experimental data.
