Hydraulic modeling of a mixed water level control hydro-mechanical gate
Résumé
The article describes the hydraulic functioning of a mixed water level control hydromechanical gate present in several irrigation canals. According to the flow conditions, this automatic gate maintains the upstream level close to a target value for low flow, then it controls the downstream level close to a target, and switches back to control the upstream level to avoid overflow. Such a complex behaviour is obtained via a series of side tanks linked by orifices and weirs. We analyze this behaviour and propose a mathematical model for its functioning, assuming the system is at equilibrium. The proposed model is analyzed and evaluated on real data fation canal in the South of France, showing the ability of the model to reproduce the functioning of this complex hydro-mechanical system
