Assessment of Landslide Risk in a Mountainous Region Using Remote Sensing and GIS Techniques

Thesis Abstract

Abstract
Landslides are natural hazards that pose significant risks to mountainous regions, causing loss of lives, infrastructure damage, and environmental degradation. Effective landslide risk assessment is crucial for mitigating these impacts and enhancing disaster resilience. This thesis focuses on the assessment of landslide risk in a mountainous region utilizing Remote Sensing and Geographic Information System (GIS) techniques. The study area, characterized by steep terrain and complex geological conditions, presents challenges for landslide risk management. Chapter 1 provides an introduction to the research topic, highlighting the background, problem statement, objectives, limitations, scope, significance of the study, and the structure of the thesis. Chapter 2 comprises a comprehensive literature review covering ten key aspects related to landslides, risk assessment, Remote Sensing, GIS applications, and methodologies employed in similar studies. Chapter 3 details the research methodology, including data collection techniques, Remote Sensing image analysis, GIS modeling approaches, and validation methods. The chapter also discusses the selection and integration of relevant datasets, software tools, and the process of developing a landslide risk assessment framework. Chapter 4 presents a detailed discussion of the research findings, including the identification of high-risk landslide areas, factors contributing to landslide susceptibility, and the validation of the developed risk assessment model. The chapter also explores the implications of the findings for disaster management and land use planning in the study area. Finally, Chapter 5 offers a conclusion and summary of the thesis, highlighting key findings, contributions to the field of landslide risk assessment, and recommendations for future research. The significance of integrating Remote Sensing and GIS technologies for enhancing landslide risk assessment capabilities is emphasized, along with the potential for informed decision-making and proactive measures to reduce vulnerability in mountainous regions. This thesis contributes to the advancement of methods for assessing landslide risk in challenging mountainous terrains, emphasizing the importance of utilizing innovative technologies for enhancing hazard mapping and disaster preparedness. The findings of this study have practical implications for policymakers, urban planners, and disaster management authorities in developing strategies to mitigate landslide risks and promote sustainable development in mountainous regions.
