Landslide susceptibility assessment using the bivariate statistical analysis and the index of entropy in the Sibiciu Basin (Romania)

摘要: The Sibiciu Basin is located in Romania between the Buzău Mountains and Buzau Subcarpathians (Curvature Carpathians Subcarpathians). geology of basin consists Paleogene flysch deposits represented by an alternation sandstones, marls, clays schists Neogene sands. area affected different types landslides (shallow, medium-deep deep-seated failures). In Romania, last decades, direct indirect methods have been applied for landslide susceptibility assessment. most utilized before 2000 were based on qualitative approaches. This study evaluates using a bivariate statistical analysis index entropy. A inventory map was prepared, estimate assessed following parameters which influence occurrence: slope angle, aspect, curvature, lithology land use. divided into five classes showing very low to high areas.
