Through model simulations different managerial solutions were evaluated for increasing waterlogging and secondary salinization in irrigated areas without sufficient natural drainage and suitable drainage outlets. Aquifer recharge in the already highlyefficient irrigation system could be reduced by shifting to a delivery-based water-pricing system. The problems were significantly delayed and crop production slightly increased. Distribution of canal water proportional to the demands produced similar results while declining water-tables were also arrested. The tested solutions delay the occurrence of waterlogging and secondary salinization, hence giving more time for the implementation of definite solutions.
