This book contains the best peer-reviewed papers accepted for presentation at the 2nd Springer Conference of the Arabian Journal of Geosciences (CAJG-2), organized in Sousse, Tunisia, in November 2019. The short papers cover various topics from the fields of (1) geological and geotechnical engineering, (2) geomechanical studies based on numerical and analytical methods, and (3) geo-informatics and remote sensing. The content of these papers provides new scientific knowledge for further understanding on landslides, new stabilization techniques, importance of geophysics for engineering geology investigations as well as new empirical approaches for easily predicting some physical and hydrogeomechanical properties of geomaterials. The book is of interest to all researchers, practitioners, and students in the fields of geological and mining engineering, geotechnical engineering, hydrogeomechanics, engineering geology, geotechnologies, and natural hazards.
