In an interdisciplinary field, geology science is related to groundwater related issues, environmental and engineering problems. So understanding geology is critical to effectively manage water resources and solve related environmental or engineering issues precisely. Geotechnical methodologies are used interdisciplinary subjects such as elementary investigation and mapping, movement pattern understanding and modelling, groundwater management and regional development policies and plans. The focus of this book includes applied geomorphology, applied geophysics and geochemistry, environmental geology and hydrogeology, natural hazards, remote sensing techniques, applied geotechnical engineering, regional geographic review and policy-make. This book also contains up-to-bottom discussions about research challenges, economy analysis and assessment the utility of geographic methodologies.
