one of the consequences of poor management and operation of irrigation systems, poor water delivery and distribution channels and divisions and consequently improper distribution of water level downstream. the study of simulation and performance evaluation software using hydrodynamic sobek varamin irrigation is done. in order to evaluate the network performance and compare the results of simula...

Water age is frequently used as a surrogate for water quality in distribution networks and often included modelling optimisation studies, though there are no reference values or standard performance functions assessing the network behaviour regarding age. This paper presents novel methodology obtaining enhanced system-specific assessment functions, tailored each network. The based on establishm...
