Abstract:
In a general sense, factors that must be considered in conjunctive use analyses have been identified and discussed. The factors have been distilled from the work of many authors who have examined numerous conjunctive systems. The methods adopted by several researchers in optimal management of conjunctive use system are critically discussed. A strategy for conjunctive use of surface & ground water based on linear programming and discrete kernel approach is proposed whose solution is very easy to obtain on a computer and an optimal cropping pattern in a reservoir command can be obtained. In this approach, rain water was also taken into account, while calculating crop water requirement. Hence, in effect, this methodology can broadly be identified as conjunctive utilization of rain-surface-ground water. This strategy will also be useful to check water-logging near canal reaches through one of the constraints.
