Modeling study demonstrates multi-objective water allocation reduces river diversion and controls salinity in arid irrigation districts, highlighting the necessity of integrated management.

Key Points

To develop an integrated sustainable management framework coupling water-salt dynamics with multi-objective optimization to quantify water-saving potential and manage soil salinity in arid regions.
Coupled a water-salt process simulation model with the NSGA-II multi-objective optimization algorithm.
Optimized trade-offs among maximized economic benefits, minimized surface water diversion, and reduced agricultural nonpoint source nitrogen loads in the Hetao Irrigation District, China.
Yellow River water diversion can be reduced to 3.69 billion m³ by limiting groundwater pumping to 700 million m³ and improving canal water delivery efficiency.
Cropping pattern adjustments and optimized irrigation quotas (2386 m³/ha for wheat, 1544 m³/ha for sunflower) achieved an economic water productivity of 2.41 yuan/m³.
Single water-saving measures proved insufficient and presented secondary environmental risks, confirming the necessity of a system-level integrated strategy.
