“…When surface irrigated areas are supplied water from public network of canal system (Santhi and Pundarikanthan, 2000), irrigation scheduling depends upon water delivery, its rate of discharge, duration and frequency. Since the farmer is not sure as to when he will have the next opportunity to irrigate his crop, he often indulges in over-irrigation, thereby defeating the purpose of conserving the water (Unger and Howell, 1999).…”

“…However, for more dependable and spatially uniform system, both D and E should be close to zero. These performance indicators promote efficient operation and management of irrigation systems for sustainability of irrigated agriculture (Mishra et al 2001) and are successfully applied to many irrigation project performance studies (Rao 1993;Perry 1996;Bos 1997;Molden et al 1998;Sakthivadivel et al 1999;Santhi and Pundarikanthan 2000).…”

“…A model based on water balance approach for low land paddy and soil moisture simulation approach for upland crops for estimating water deliveries at tertiary and secondary canals was developed by Kemachandra and Murty (1992). Santhi and Pundarikanthan (2000) developed a multi-criteria rotational scheduling procedure for an irrigation system in India, where rotational distribution was practiced at distributary canal level. Mishra et al (2002) presented some alternative delivery scheduling approaches intended to overcome the problem of low efficiency in the RBMC system of Kangsabati irrigation project, located in the state of West Bengal, India.…”

Alternative delivery scheduling approaches were tried to overcome the problem of low efficiency in eastern Indian irrigation projects. The features of the existing delivery schedules in the Left Bank Feeder Canal (LBFC) system of Kangsabati irrigation project, located in the state of West Bengal, India, have been studied. Four simulation scenarios were considered in the study. These are (1) actual canal scheduling with original transplanting date (S1), (2) Integrated Reservoirbased Canal Irrigation Model (IRCIM) scheduling for usual transplanting date (S2), (3) IRCIM scheduling for 5 days advanced transplanting date (S3), and (4) IRCIM scheduling for 5 days lagged transplanting date (S4). An attempt was made to develop a year-independent alternative delivery schedule based on the analysis of 11 years simulation results with all the above scenarios. For maximum number of simulation years, model performance was better for paddy transplanted on July 24, three irrigations from the reservoir between transplanting and harvesting, and restricting the release to minimum rule curve (MRC), i.e., maintaining the stage on any day above the minimum stage actually found in 16 years period. Hence, it was proposed as the year-independent alternative delivery schedule. This alternative delivery schedule saved 18.36% irrigation water over actual schedules, but increased the crop evapotranspiration by 0.61%. The proposed alternative delivery schedule also considered both the expected dry spells as well as critical growth periods of the crop during the simulation period. Thus, it was recommended to adopt the alternative A. Bhadra et al. delivery schedule instead of existing delivery schedule in the future years for the LBFC system of Kangsabati irrigation project.

“…The model was used in a small command area and emphasis was put on crop production in relation to water supply. Santhi and Pundarikanthan (2000) formulated a multi-criteria mathematical model for canal irrigation scheduling in rotational distribution to achieve the objectives of minimizing gate operations, improving performance of equity, adequacy and timeliness. The multiobjectives of water distribution were expressed in terms of measurable criteria on a weight basis and they in turn form the basis for design of the scheduling model.…”

Yield failure is often caused by the uncertainty of supply or the shortage of water at the critical period of crop growth. This situation compels farmers and engineers to find ways to efficiently use the available resource. Reduction of irrigation depth or extension of irrigation interval are the methods commonly adopted. Another alternative is the application of the rotational irrigation technique instead of continuous irrigation. The question is how to adjust the water supply to minimize crop yield losses. Water supply itself is a dynamic parameter depending on farm size, canal capacity and crop growth stages. The distribution factor (DF) is a technique of water distribution based on the dynamic character of the supply over the growth stages. It allows categorization of the allocation of the available water in the farm within the limit of the channel capacity to satisfy crop water needs. The procedure was applied to a set of 24 farms in 2006 in the Chianan Irrigation Association which frequently experiences water shortages. The results showed that if a uniform reduction of water supply could be applied during moderate water shortages, DF made it possible to rationally distribute water among rotational groups in severe shortage conditions.
