Abstract

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.
阿尔及利亚东北部安纳巴省使用WEAP模型模拟当前和未来用水需求:案例研究
阿尔及利亚的安纳巴省目前正面临着水资源短缺和间歇性供水的重大挑战。本研究利用水资源评估与规划(WEAP)系统来评估阿尔及利亚安纳巴省目前和未来的水资源供应和需求。评估了包括参考、气候变化、海水淡化、减少泄漏和水再利用在内的五种情景。分析显示,该地区面临严重的水资源短缺和间歇性分布,预计到2070年,年需水量将达到148立方毫米。气候变化将使需求增加8%,预计到2070年用水量将达到151立方毫米。工业部门未满足的用水需求最高,而家庭和农业部门也面临挑战。其他方案,如用水效率和海水淡化,为消除工业未满足的用水需求提供了潜力。到2070年,情景5(管理含水层补给)将使工业未满足的用水需求减少36%,达到23立方毫米,而情景4(减少泄漏和水再利用)将使未满足的家庭需求减少到24立方毫米。本研究强调需要制订水管理战略,包括有效用水、基础设施投资、关于节约用水和再利用的公众教育以及工业采用节水技术。总体而言,本研究解决了与安纳巴省水资源短缺相关的困难和挑战。
