摘要

由于地质复杂、自然补给条件有限，在干旱的环形山中确定可持续的人工补给区具有挑战性，因此很难进行准确的选址和管理。本研究整合了垂直电探测（VES）、层次分析法（AHP）和布尔分析法，以确定印度干旱的邦德尔康德喀斯特地区的可持续人工补给区。含水层厚度和裂缝是决定地下水补给条件的关键因素，显示了整个研究区域不同程度的补给适宜性。溪流沿岸约有 2.31% 的区域（13.36 平方公里）具有 "非常高 "的适宜性，8.09% 的区域（45.82 平方公里）具有 "高 "的适宜性。"中度 "适宜性占 17.86%（101.66 平方公里），"低 "适宜性占 38.85%（218.39 平方公里），"极低 "适宜性占 17.35%（98.75 平方公里）。东北部和中部的补给潜力最大，流域中部的补给潜力最小。研究表明，这种综合方法大大提高了精确度，精确度从 71.40% 提高到 85.70%，F1 分数从 0.833 提高到 0.923，超过了单独使用 AHP 方法的性能。研究结果凸显了战略性选择和锁定特定地点进行人工补给的重要性，因为尽管有 43% 的区域显示出地下水的潜力，但只有 18% 的研究区域适合进行人工补给。事实证明，采用 VES 的 AHP 比采用 VES 的模糊-AHP 更精确、更可靠，AHP 的保守方法将 55.70% 的区域划分为非常低至低适宜性区域，而 Fuzzy-AHP 为 41.92%，从而确保只选择最适宜的地点。与电阻率断层扫描法相比，VES 具有成本效益高、无损伤、可快速生成一维地下模型等优点，但其细节较少。当与 AHP 结合使用时，VES 可增强对不断变化的条件的适应性，强调生态保护和气候变化适应能力。这种方法可有效解决干旱地区的水资源挑战，促进可持续水资源管理。

Identifying potential artificial recharge zone in an arid craton

Identifying sustainable artificial recharge zones in arid cratons is challenging due to complex geology and limited natural recharge conditions, making accurate site selection and management difficult. This study integrates Vertical Electrical Sounding (VES), the Analytic Hierarchy Process (AHP), and Boolean analysis to identify sustainable artificial recharge zones in the arid Bundelkhand craton of India. Aquifer thickness and fractures emerged as critical determinants of groundwater recharge conditions, revealing varying degrees of suitability for recharge across the study area. Approximately 2.31% (13.36 km²) of the area along streams exhibited "very high" suitability, while 8.09% (45.82 km²) had "high" suitability. “Moderate" suitability covered 17.86% (101.66 km²), "low" suitability accounted for 38.85% (218.39 km²), and "very low" suitability represented 17.35% (98.75 km²) of the area. Recharge potential was highest in the northeast and central parts, with the middle of the watershed exhibiting the lowest potential. The study demonstrated that this integrated approach significantly improved precision from 71.40% to 85.70% and enhanced the F1 score from 0.833 to 0.923, surpassing the performance of the AHP method alone. The findings highlighted the importance of strategic selection and targeting of specific locations for artificial recharge, as only ∼18% of the study area was suitable for such efforts, despite ∼43% showing potential for groundwater. AHP with VES proves more precise and reliable than Fuzzy-AHP with VES, with AHP's conservative approach classifying 55.70% of the area as very low to low suitability compared to Fuzzy-AHP's 41.92%, ensuring only the most suitable sites are selected. VES offers cost-effectiveness, noninvasiveness, and rapid generation of a 1D subsurface model, balancing its lower detail compared to Electrical Resistivity Tomography. When combined with the AHP, VES enhances adaptability to changing conditions, emphasizing ecological preservation and climate change resilience. This approach effectively addresses water challenges in arid regions, contributing to sustainable water resource management.

期刊介绍： Groundwater for Sustainable Development is directed to different stakeholders and professionals, including government and non-governmental organizations, international funding agencies, universities, public water institutions, public health and other public/private sector professionals, and other relevant institutions. It is aimed at professionals, academics and students in the fields of disciplines such as: groundwater and its connection to surface hydrology and environment, soil sciences, engineering, ecology, microbiology, atmospheric sciences, analytical chemistry, hydro-engineering, water technology, environmental ethics, economics, public health, policy, as well as social sciences, legal disciplines, or any other area connected with water issues. The objectives of this journal are to facilitate: • The improvement of effective and sustainable management of water resources across the globe. • The improvement of human access to groundwater resources in adequate quantity and good quality. • The meeting of the increasing demand for drinking and irrigation water needed for food security to contribute to a social and economically sound human development. • The creation of a global inter- and multidisciplinary platform and forum to improve our understanding of groundwater resources and to advocate their effective and sustainable management and protection against contamination. • Interdisciplinary information exchange and to stimulate scientific research in the fields of groundwater related sciences and social and health sciences required to achieve the United Nations Millennium Development Goals for sustainable development.
