Assessment of Groundwater Quality in Urban Areas Using GIS and Remote Sensing Techniques

Thesis Abstract

Abstract
This thesis presents a comprehensive study on the assessment of groundwater quality in urban areas utilizing Geographic Information System (GIS) and Remote Sensing techniques. Groundwater is a vital natural resource that serves as a primary source of drinking water for urban populations. However, rapid urbanization and industrialization have led to various anthropogenic activities that pose a threat to groundwater quality. This research aims to assess the quality of groundwater in urban areas by integrating GIS and Remote Sensing technologies to provide a detailed spatial analysis of the distribution and contamination levels of groundwater. The study begins with an introduction that highlights the importance of groundwater quality assessment in urban areas and the significance of utilizing GIS and Remote Sensing techniques in this context. The background of the study provides an overview of the existing literature on groundwater quality assessment, GIS, and Remote Sensing applications in environmental studies. The problem statement identifies the current challenges and issues related to groundwater quality in urban areas, emphasizing the need for a systematic and integrated approach to assess and monitor groundwater quality. The objectives of the study are outlined to investigate the spatial distribution of groundwater quality parameters, identify potential sources of contamination, and develop a framework for mapping and analyzing groundwater quality data using GIS and Remote Sensing technologies. The limitations of the study are acknowledged, including data availability, accuracy of remote sensing images, and potential limitations in the field sampling techniques. The scope of the study focuses on a specific urban area, where groundwater quality data will be collected, analyzed, and mapped for further interpretation and decision-making. The significance of the study lies in its contribution to the body of knowledge on groundwater quality assessment in urban areas, providing valuable insights for policymakers, urban planners, and environmental researchers. The structure of the thesis is outlined to guide the reader through the chapters, which include a literature review, research methodology, discussion of findings, and conclusion. The literature review chapter critically examines previous studies on groundwater quality assessment, GIS applications, and Remote Sensing techniques, providing a comprehensive review of the existing literature to support the research objectives. The research methodology chapter details the data collection methods, sampling techniques, laboratory analysis procedures, GIS and Remote Sensing tools used for data processing, and statistical analysis techniques applied in the study. The discussion of findings chapter presents the results of the groundwater quality assessment, spatial distribution maps of key parameters, identification of contamination sources, and interpretation of the findings in relation to urban development and land use patterns. In conclusion, this thesis contributes to the understanding of groundwater quality assessment in urban areas through the integration of GIS and Remote Sensing technologies. The study provides valuable insights into the spatial distribution of groundwater quality parameters, identifies potential sources of contamination, and offers recommendations for sustainable groundwater management practices in urban environments.
