The system is managed by an integrated control system that combines a SCADA system and data historian with a hydrological and hydraulic model.The system runs in hydrological mode to model rainfall forecast data to predict the expected water volume that will runoff into the canal. This sets a target canal level for a proportion of the predicted runoff. A complete hydraulic model is then run using the monitored flows and levels from the outstations as the initial conditions. Real-time logic control determines the optimised combination of feeder and discharge sluice positions to achieve the target level. The sluice positions are communicated to the SCADA system, which relays them to the feeder and discharge sluices, and the drawdown of the canal begins.Collaboration has been key to the success of this project, as it was complex and had many stakeholders. We are proud of our involvement and look forward to the seeing the benefits that this innovation brings.Oliver Mangham, Applications Director at Fairfield. servers and a redundant, secure networkmodel.
