摘要

地下水被认为是最可靠的淡水来源。由于人口增加、城市化和工业化等多种因素,地下水供应正面临严重威胁。合理精确地寻找地下水往往是一项艰巨的任务。在这项工作中,借助基于地理信息系统(GIS)和遥感技术(RS)的层次分析法(AHP),绘制了印度邦德尔康德克拉通地区的地下水潜势区(GWPZs)图。在地理信息系统环境中,利用遥感数据生成了各种影响地下水的要素。AHP 方法用于确定应分配给每个影响要素及其子特征的权重。为了确定研究区域的 GWPZ,在分配了适当的权重后,将每个专题图层合并到前一个专题图层之上。因此,所获得的 GWPZ 被划分为五个不同的等级,分别称为 "极低"、"低"、"中等"、"高 "和 "极高 "GWPZ。研究结果显示,"极高 "全球降水分级区占整个研究区域的 1.42%(380.55 平方公里),"高 "全球降水分级区占 12.48%(3340.63 平方公里),"中等 "全球降水分级区占 67.83%(18152.1 平方公里),"低 "全球降水分级区占 17.26%(4619.64 平方公里),"极低 "全球降水分级区占 1%(267.85 平方公里)。所取得的结果在水井排水率数据的帮助下得到了验证。总之,这项研究提供了一种划定地下水潜力的技术,对管理地下水资源很有帮助。

Analytical Hierarchy process and geospatial techniques for Delineation of Groundwater potential zones in Bundelkhand Craton Region, India

Groundwater is considered to be the most reliable source of fresh water. Groundwater supplies are under grave danger due to a number of factors, including an increasing population, urbanization, and industry. Finding groundwater with reasonable precision is frequently a difficult task. In this work, the groundwater potential zones (GWPZs) in the Bundelkhand Craton region of India are mapped out with the help of analytical hierarchy processes (AHP) that are based on Geographic Information Systems (GIS) and remote sensing (RS) techniques. Various groundwater affecting elements has been generated with the remote sensing data in GIS environment. The AHP method was used to determine the weights that should be allocated to each affecting elements and their sub-features as well. In order to determine the GWPZs of the research region, each of these thematic layers was combined on top of the previous one after the appropriate weights were assigned. As a result, the GWPZs that were acquired were divided into five distinct classes, which were respectively designated as “very low”, “low”, “moderate”, “high”, and “very high” GWPZs. The findings of this study showed that "very high" GWPZ comprises 1.42% (380.55 km2), "high" GWPZ comprises 12.48% (3340.63 km2), "moderate" GWPZ comprises 67.83% (18152.1 km2), "low" GWPZ comprises 17.26 (4619.64 km2), and "very low" GWPZ comprises 1% (267.85 Km2) of the overall studied region. The result that was achieved is verified with the assistance of well discharge rate data. Overall, this research provides a technique to delineate groundwater potentiality, which will be very helpful for managing groundwater resources.

期刊介绍: Applied Geomatics (AGMJ) is the official journal of SIFET the Italian Society of Photogrammetry and Topography and covers all aspects and information on scientific and technical advances in the geomatics sciences. The Journal publishes innovative contributions in geomatics applications ranging from the integration of instruments, methodologies and technologies and their use in the environmental sciences, engineering and other natural sciences. The areas of interest include many research fields such as: remote sensing, close range and videometric photogrammetry, image analysis, digital mapping, land and geographic information systems, geographic information science, integrated geodesy, spatial data analysis, heritage recording; network adjustment and numerical processes. Furthermore, Applied Geomatics is open to articles from all areas of deformation measurements and analysis, structural engineering, mechanical engineering and all trends in earth and planetary survey science and space technology. The Journal also contains notices of conferences and international workshops, industry news, and information on new products. It provides a useful forum for professional and academic scientists involved in geomatics science and technology.
