This book explores the use of advanced geospatial techniques in geomorphic hazards modelling and risk reduction. It also compares the accuracy of traditional statistical methods and advanced machine learning methods and addresses the different ways to reduce the impact of geomorphic hazards.
In recent years with the development of human infrastructures, geomorphic hazards are gradually increasing, which include landslides, flood and soil erosion, among others. They cause huge loss of human property and lives. Especially in mountainous, coastal, arid and semi-arid regions, these natural hazards are the main barriers for economic development. Furthermore, human pressure and specific human actions such as deforestation, inappropriate land use and farming have increased the danger of natural disasters and degraded the natural environment, making it more difficult for environmental planners and policymakers to develop appropriate long-term sustainability plans. The most challenging task is to develop a sophisticated approach for continuous inspection and resolution of environmental problems for researchers and scientists. However, in the past several decades, geospatial technology has undergone dramatic advances, opening up new opportunities for handling environmental challenges in a more comprehensive manner.
With the help of geographic information system (GIS) tools, high and moderate resolution remote sensing information, such as visible imaging, synthetic aperture radar, global navigation satellite systems, light detection and ranging, Quickbird, Worldview 3, LiDAR, SPOT 5, Google Earth Engine and others deliver state-of-the-art investigations in the identification of multiple natural hazards. For a thorough examination, advanced computer approaches focusing on cutting-edge data processing, machine learning and deep learning may be employed. To detect and manage various geomorphic hazards and their impact, several models with a specific emphasis on natural resources and the environment may be created.

He is also interested in the applications of remote sensing and GIS in geo-hazard modelling and management. He has more than 7 years of teaching and research experience. His name has been listed in the top 2% of world scientists (2021, 2022 &2023) published by Stanford University, USA. He has guided many Ph.D. scholars in the field of geo-hazard management. More than 36 students have completed their dissertations under his guidance at the post-graduate level. He has published 72 peer-reviewed research papers in international journals of Elsevier, Springer, Taylor and Francis and the Multidisciplinary Digital Publishing Institute (MDPI). He has also published 5 book chapters. He is a reviewer of research articles assigned by leading international journals such as the Journal of Cleaner Production, Science of the Total Environment, Environmental Development and Sustainability, Geocarto International, Geomorphology, etc.
Dr. Basanta Raj Adhikari is working as a director at the Centre for Disaster Studies, Institute of Engineering, Tribhuvan University, Nepal, and is also an assistant professor of engineering geology in the same university. Moreover, he is also a high-level foreign associate professor at Sichuan University, China and Guest Professor at Keio University, Japan. Dr. Adhikari has a research interest in the tectonics of the Himalaya, climate change, hill-slope movement and human interaction, Himalayan sediment flux generation and disaster risk reduction. He is the author of more than 50 scientific articles and book chapters and has received various expressions of recognition for his work in the field of earth science including Young Scientist (Integrated Research on Disaster Risk), “young affiliates” (The World Academy of Sciences) and Sichuan 1000 Talents (Sichuan Province, China). Currently, he serves as an editor of the Journal of Coastal and Riverine Flood Risk and the thematic article collections of Environmental Change Driven by Climate Change, Tectonism and Landslide.
