Optimal allocation of regional water resources in an arid basin: insights from Integrated Water Resources Management

Abstract Viewing water management as a multifaceted issue is critical to achieving sustainable management. This paper proposes an integrated optimal allocation model for aquifer sustainability and environmental benefits when managing conjunctive resources. Optimization techniques such genetic algorithm (GA) non-dominated sorting (NSGA-II) are used balance economic benefit demand based on decision makers’ preferences. The findings indicate that less was allocated industries with high demand. value of the these between 34 52%. Thus, it concluded specific unsustainable damage considered. From scenarios examined, scenario 10 (water resource conditions demands determined existing conditions, considering domestic restoration) found be scenario. indicators Integrated Water Resources Management (IWRM) this 0.30, 0.15, 190, 40.9, 0.55 relative stress, sustainability, attenuation period, recovery potential, agricultural productivity, respectively. finding implies management, wastewater treatment, absence industrial development in scenarios, will possible conserve aquifers meet demands.
