Three cases are suggested: I. Surface irrigation system and clay soil, II. Trickle irrigation system and sand soil and III. Trickle irrigation system and clay soil. These cases are studied with six different salt-tolerant crop patterns. Adopting the suggested strategies are to reduce or eliminate the impact of salinity by maximizing the revenue of irrigation project especially in degraded land with salts without reclamation the lands. Cost estimation is carried out to initial cost and annual cost to evaluate the three different cases using four life cycle cost (LCC) method and evaluated using four economic feasibility studies methods: I. Net present value (NPV), II. Benefit cost ratio (B/C), III. Internal rate of return (IRR) and IV. Payback period (n). Design curve is drawn for different studied salinity values for the three cases to find the best alternative and best crop pattern for each salinity value
