Régulations en rivière
Cie d'Aménagement des Côteaux de Gascogne
In SW-France, irrigation and water supply generally use direct pumping in rivers. The upstream flow is regulated through a dam. The management of these hydraulic systems is geared to satisfying water demands white complying wilh the downstream flow orders and saving water as much as possible * Such a management can be optimized thanks to the exisling simulation software as well as methods of automatics ; the former leads to a correct modelisation of the hydraulic system operation. It becomes therefore possible to get a better knowledge of its overall dynamics and to understand interactions between inflow, withdrawals and various perturbations. Once such an understanding achieved, technics of automatics help to determine the optimum orders to be carried out at the dam, as well as to detect the perturbations and react to them. Testing and improving regulation can be done through the simulation tools.
