Following a presentation of the operational challenges faced by the canal managers, the use of a simulation model to improve the manual operation procedures of an irrigation canal is detailed. The pilot field site for this IIMI-CEMAGREF collaboration is the Kirindi Oya Right Bank Main Canal (Sri Lanka). The simulation model RBMC is a fully interfaced hydrodynamic model solving complete Saint-Venant equations. Its first applications provided detailed information on canal behavior and a diagnosis on the present manual operation procedures. Its integration in a broader Management Information System provided canal managers with a decision- support package helping them to improve operational procedures. These improvements contributed to increase the water use efficiency.

Doctoral thesis presented to ENGREF (Ecole National du Genie Rural, des Eaux et des Forets), 27 January 1994. Methods of automatic control have been developed for irrigation canals since 1970, mainly in France and USA. These methods can be classified according to four concepts: Controlled variables, control logic, design method and implementation. Optimal control, a multivariable method, is developed in this thesis. The required linear model is obtained from Saint-Venant equations, discretised with Preissmann implicit scheme. One advantage of this scheme is not to be constrained by Courant condition. A special modelisation is used for boundary conditions, in order to obtain a controllable system and to limit input velocities. A method is presented that evaluates the modelisation and control time step. The optimal controller can address tracking issues and use prediction of offtake withdrawals. A complete and reduced order state observer are proposed. A perturbation observer is also defined, reconstructing unknown offtake withdrawals and therefore improving the state reconstruction. A method is suggested that initialises the weighting matrices. The optimal controller and the reduced observer are tested on two examples: A low and a high head loss canal reach. Robustness is evaluated, by simulation on a degraded system. Results prove the controller and the observer to be very satisfactory. Finally, results are compared, to other well-known regulation methods.

This article suggests and defines a characterization of irrigation canal regulation methods, based on four criteria: considered variables (controlled, measured, and control action variables), logic of control, design method (structure and technique) and field implementation (configuration and device). Depending on the chosen criterion and partition rule, different classifications can be built from this characterization. In conclusion, a structured characterization table of the main published canal regulation method is presented.

The management of a manually operated irrigation canal with a number of control structures presents a special set of challenges to the system manager, who is often confronted with the problem of identifying and implementing a coordinated operational strategy to meet water delivery targets in the absence of adequate and reliable information on how the system is functioning. The development of a microcomputer-based mathematical flow simulation model of the Kirindi Oya Right Bank Main Canal is the first phase in IIMI's efforts to provide canal managers with an innovative decision-support tool to help them meet these challenges. This research project was also the beginning of a fruitful, mutually rewarding and lasting relationship between the International Irrigation Management Institute (11MI) and the Centre National du Machinisme Agricole, du Genie Rural, des Eaux et. des Forets (CEMAGREF). This research paper, co-authored by staff members of both institutions, is yet another outcome of this excellent, collaborative relationship.
