Next to “God”, many people and organizations deserve heartfelt thanks for their precious contributions to this study. I express my heartfelt gratitude and indebtedness to my advisor Dr. K.V.Suryabhagavan and to my Co-advisor Prof. M.Balakrishnan, who helped me from the very beginning of the research to its compilation and for sharing me their time for valuable discussions and giving me their kind helpful guidance throughout this study. Further, I would like to extend my thanks to all Earth Science Department staff members and Remote Sensing and Geo-informatics stream staff members for securing lab. facility and unreserved support. I have a great gratitude to acknowledge the Ethiopian Mapping Agency, Central Statistical Agency, Ethiopian Geological Survey and Ethiopian Meteorology Agency for providing me the necessary data and information to carry out this study. Special thanks go to all my family members and my classmates for their appreciation and continuous support. Finally, I want to thank all of those people who, once upon time, were my teachers, Friends and others, who helped me, to begin this long journey. Their names are too numerous to list, but many of them inspired me to learn and upgrade. i Table of Contents Acknowledgments .......................................................................................................................... i List of Tables ................................................................................................................................ vi List of Figures .............................................................................................................................. vii List of Appendices ........................................................................................................................ ix List of Acronyms ........................................................................................................................... x Abstract ......................................................................................................................................... xi CHAPTER ONE ........................................................................................................................... 1 1.
