摘 要:Equitable water allocation is essential in an irrigation scheme for obtaining potential crop yields from the entire scheme,especially when water supply is *** optimization model achieved this goal by coupling an optimal water allocation model with available water supply and irrigation water demand for a river-fed rice irrigation system in *** model consists of a paddy field water balance module and an optimization *** outputs from the module are daily irrigation demand and surface runoff,if there is *** optimization module consists of an objective function,which minimizes water shortage across the scheme area while maintaining equity in water *** model performs optimization subject to several system constraints,and the decision variable of the model is daily releases or supply to the tertiary *** of this model remained unaffected under different water supply conditions,and the optimization model reliably examined the effects of alternate water allocation and management rules with field *** improves efficiency and equity in water allocation with respect to crop growth stages and water shortages rather than simply cutting irrigation supply on a proportional basis to overcome water shortages.
