Thesis Overview

The project titled "Analysis of groundwater quality in a selected region using GIS and remote sensing techniques" aims to investigate and assess the quality of groundwater in a specific region by utilizing Geographic Information System (GIS) and remote sensing technologies. Groundwater is a vital natural resource that plays a crucial role in sustaining ecosystems, supporting agricultural activities, and providing drinking water to communities. However, the quality of groundwater can be affected by various natural and anthropogenic factors, such as land use practices, industrial activities, and pollution sources. The utilization of GIS and remote sensing techniques in this study offers a powerful and efficient means to analyze and visualize spatial data related to groundwater quality. GIS enables the integration of various data layers, such as geological information, land use patterns, and water quality measurements, to create comprehensive maps and models for better understanding the distribution and characteristics of groundwater in the study area. Remote sensing, on the other hand, provides valuable imagery and data from satellites and aerial platforms, allowing for the monitoring and assessment of land surface changes and environmental conditions that may influence groundwater quality. The research will begin with a thorough literature review to explore existing studies, methodologies, and technologies related to groundwater quality assessment, GIS, and remote sensing applications. This review will provide a solid foundation for the research methodology, which will involve data collection, analysis, and interpretation using GIS software and remote sensing tools. Various parameters affecting groundwater quality, such as pH levels, dissolved oxygen, nitrates, and other contaminants, will be measured and mapped to identify potential sources of pollution and areas of concern. The study area will be carefully selected based on specific criteria, such as known pollution sources, land use patterns, and hydrogeological characteristics. Fieldwork will be conducted to collect water samples from wells, boreholes, and surface water bodies for laboratory analysis and validation of remote sensing data. GIS will be utilized to create thematic maps illustrating groundwater quality parameters, contamination hotspots, and potential risks to human health and the environment. The results of the analysis will be discussed in detail in the findings chapter, highlighting key findings, trends, and spatial patterns observed in the groundwater quality data. The implications of the study will be assessed in terms of environmental management, water resource planning, and potential remediation strategies to mitigate groundwater pollution and safeguard water quality in the region. Finally, the conclusion chapter will summarize the research outcomes, provide recommendations for future studies, and emphasize the importance of integrating GIS and remote sensing technologies in groundwater quality assessment and management practices. Overall, this project aims to contribute valuable insights into the assessment and monitoring of groundwater quality using advanced spatial analysis techniques, with the ultimate goal of promoting sustainable water resource management and environmental protection in the selected region.
