Improved Planning Model for Canal Scheduling of Rotational Irrigation

摘要

This paper depicts some limitations of a canal scheduling model that gives water delivery schedules for a rotational distribution system using the concept of weights based on the irrigation performance indicators. The indicators used are equity, adequacy, timeliness, and location (based on the convenience of gate operator). Possible improvements in the model are suggested to remove the drawbacks of untimely water supplies to some of the distributaries, poor supply to demand ratios, and the inconveniences faced by the gate operator in opening some of the distributaries. This proposed model is designated as the improved planning model for canal scheduling. Based on this, a canal operational schedule is recommended for the whole irrigation distribution system for the kharif season, which is more effective in fulfilling the multiple objectives of irrigation.
