This paper presents an application of Kalman Filtering on an open-channel hydraulic system, to estimate unknown discharges at lateral offtakes and head-loss coefficients at cross-regulators using only water level measurements upstream and downstream of each pool. This information is useful for the automatic control of these hydraulic systems, such as irrigation or navigation canals. The convergence properties of such Kalman Filters are also studied and it can be mathematically verified how many measurements are required to allow such identification. The methodology is illustrated on a 15 km-long 5-pool benchmark irrigation canal.
