Simulation of current and future water demands using the WEAP model in the Annaba province, Northeastern Algeria: a case study
The Annaba province in Algeria is currently facing significant challenges due to water shortages and intermittent water distribution. This study utilizes the Water Evaluation And Planning (WEAP) system to assess present and future water supply and demands in Annaba province, Algeria. Five scenarios, including a reference, climate change, desalination, leakage reduction, and water reuse, are evaluated. The analysis reveals that the region faces significant water shortages and intermittent distribution, with projected annual water demand reaching 148 Mm3 by 2070. Climate change amplifies the demand by 8%, resulting in a projected water demand of 151 Mm3 by 2070. The industrial sector exhibits the highest unmet water demand, while the domestic and agricultural sectors also face challenges. Alternative scenarios, such as water efficiency and desalination, offer potential for eliminating industrial unmet water demand. Scenario 5 (managed aquifer recharge) reduces industrial unmet water demands by 36% to 23 Mm3 by 2070, while scenario 4 (leakage reduction and water reuse) decreases unmet domestic demands to 24 Mm3. This study emphasizes the need for water management strategies including efficient water use, infrastructure investment, public education on conservation and reuse, and industry adoption of water-saving technologies. Overall, this study addresses the difficulties and challenges associated with water scarcity in Annaba province. HIGHLIGHTS We explored alternative development scenarios by implementing various hypothetical water futures. These scenarios assess different approaches to water management, aiding decision-makers in understanding potential benefits and trade-offs. Examining alternative water futures, researchers, and policymakers can identify strategies for ensuring a sustainable water supply amidst changing conditions like population and climate.; By exploring hypothetical water scenarios, we promote integrated approaches to resilient solutions. This involves highlighting climate-resilient infrastructure, advanced technologies, effective governance, and collaborations with stakeholders for sustainable insights.;
