Abstract The purpose of the current study is to produce landslide susceptibility maps using different probabilistic and bivariate statistical approaches; namely, frequency ratio (FR), weights-of-evidence (WofE), index-of-entropy (IofE), and Dempster–Shafer (DS) models, at Wadi Itwad, Asir region, in the southwestern part of Saudi Arabia. Landslide locations were identified and mapped from in- terpretation of high-resolution satellite images, historical records, and ... إقراء المزيد

ABSTRACT In the recent years, the Egyptian government and private sector have been interested in developing the desert areas that located between the limestone plateau and the recent flood plain of the River Nile both the east and west sides. These areas represent a corner stone as a source of aggregate materials that used essentially as sub - base materials ... إقراء المزيد

Field work for discrimination between different rock units is a very tedious oneand a time consuming. However, by using remote sensing techniques the differentiation become easier and time save. The current work is very important in the field of sedimentary rocks, especially because few authors used remote sensing techniques in sedimentary rock discrimination and can provide a good background for ... إقراء المزيد
