Abstract
A mixed-integer program is presented for scheduling canal irrigation among a group of users where the duration of flow of each outlet and a target sta rt time is specified by the users. Two models are developed. The first is a single-period model which uses as input a minimized demand at the head of the canal. This will allow the discharge at the head of the canal to be set once at the beginning of the irrigation period. Within this constraint, th e single-period model minimizes the sum over all outlets of the difference between the scheduled start time of flow to each user and the requested tar get start times. The second model is a multiperiod model. This model favors those users who had been disadvantaged in the previous irrigation periods by giving them priority in scheduling their actual start times with target start times for the subsequent irrigation period. The proposed models can b e used to support decisions in irrigation schemes operating on an arranged demand.
