Abstract

Groundwater availability in the Zakho Basin faces significant challenges due to political issues, border stream control, climate change, urbanization, land use changes, and poor administration, leading to declining groundwater quantity and quality. To address these issues, this study utilized the Analytic Hierarchy Process (AHP) and geospatial techniques to identify potential groundwater sites in Zakho. The study assigned weights normalized through the AHP eigenvector and created a final index using the weighted overlay method and specific criteria such as slope, flow accumulation, drainage density, lineament density, geology, well data, rainfall, and soil type. Validation through the receiver operating characteristic (ROC) curve (AUC = 0.849) and coefficient of determination (R2 = 0.81) demonstrated the model’s accuracy. The results showed that 17% of the area had the highest potential as a reliable groundwater source, 46% represented high-to-moderate potential zones, and 37% had low potential. Flat areas between rivers and high mountains displayed the greatest potential for groundwater development. Identifying these potential sites can aid farmers, regional planners, and local governments in making precise decisions about installing hand pumps and tube wells for a regular water supply. Additionally, the findings contribute to the development of a sustainable groundwater management plan, focusing on improving water usage and protecting water-related ecosystems in the region. Identification of the optimum influencing factors, arrangement of the factors in a hierarchy, and creation of a GWPI map will allow further planning for groundwater preservation and sustainability. This project can be conducted in other areas facing droughts.
基于AHP-GIS的地理空间多准则评价在伊拉克库尔德斯坦地区Zakho盆地圈定地下水潜力带
由于政治问题、边境河流控制、气候变化、城市化、土地利用变化和管理不善,导致地下水数量和质量下降,Zakho盆地的地下水供应面临重大挑战。为了解决这些问题,本研究利用层次分析法(AHP)和地理空间技术来确定Zakho潜在的地下水点。该研究通过AHP特征向量归一化分配权重,并使用加权叠加法和特定标准(如坡度、流量积累、排水密度、线状密度、地质、井数据、降雨量和土壤类型)创建最终指数。通过受试者工作特征(ROC)曲线(AUC = 0.849)和决定系数(R2 = 0.81)验证了模型的准确性。结果表明,该地区17%的地区具有最高潜力,46%的地区具有中高潜力,37%的地区具有低潜力。河流和高山之间的平坦地区显示出地下水开发的最大潜力。确定这些潜在的地点可以帮助农民、地区规划者和地方政府做出精确的决定,安装手动泵和管井,以实现常规供水。此外,研究结果有助于制定可持续地下水管理计划,重点是改善该地区的水资源利用和保护与水有关的生态系统。确定最佳影响因素,按层次排列因素,并创建GWPI地图,将有助于进一步规划地下水保护和可持续性。这个项目可以在其他面临干旱的地区进行。

期刊介绍: Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
