The water management simulation model DRAINMOD-S was applied to simulate different strategies for using agricultural drainage water for irrigation over a 20-year period. The irrigation strategies considered were: (i) fresh/non-saline water as the baseline for comparison; (ii) drainage water of different salinities; (iii) cyclic use of fresh water and drainage water; (iv) deficit irrigation combined with controlled drainage; and (v) interseasonal cyclic use of drainage water and fresh water (2 years drainage/2years fresh).
