Abstract A computer-based hydraulic model,RAJBAH, was used to assess the utility of such models to assist and support canal system managers in planning and targeting maintenance activities on secondary canals. The work was conducted on Lagar distributary, a secondary channel off-taking from Upper Gugera Branch canal, Lower Chenab Canal system, Punjab, Pakistan. Measured discharges of off-takes and water levels along the distributary for premaintenance and post-maintenance periods were obtained. These data were used to assess the impact of actual maintenance inputs at specific locations identified in a model application in 1989. The predicted results of the model were satisfactorily close to conditions measured in the field. The study confirmed that suitably calibrated hydraulic simulation models can be effectively used in a decision support planning capacity to target and prioritize maintenance inputs for secondary canals in the irrigation systems of Pakistan's Punjab.
