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.

Development of a canal model system with automatic control
Author : Chen Wenxue1, Guo Xiaocheng1, Cui Wei1, Wu Yihong1, Xu Jianqiang2
A model canal is described in this paper, which is about 300m long and is divided into 5 canal pools with different length by 5 sluice gates driven by AC servo motors. There are 5 offtakes along the canal system, and their flowrates are measured by means of turbo flowmeters. For measuring water level, 15 water level sensors are installed along the canal. And 5 PLCs for driving the 5 sluice gates are connected with a computer through a modem by means of Ethernet cables. The SCADA system is developed by means of LabView. The canal is operated under constant downstream water depth, and it is controlled by a PI controller which consists of a feedforward control loop, a feedback control loop and a decoupler. The control algorithm is tested on this canal model and the control parameters are tuned on line.
