Land Slides and Rock Falls

Chronology of rock falls and slides in a desert mountain range: Case study from the Sonoran Desert in south-central Arizona

مقایسه روش های رگرسیون لجستیک، نسبت فراوانی و تحلیل سلسله مراتبی در تهیه ی نقشه ی حساسیت ریزش‌سنگ (مطالعه موردی: استان کردستان، گردنه صلوات آباد)

Rock falls are natural process of activities geomorphic on steep slopes in mountainous terrains. At this research, rock fall susceptibility mapping was generated by logistic regression (LR), frequency ratio (FR) and analytical hierarchy process (AHP) at a long 11 km of the Salavat Abad road in the eastern of Sanandaj, Kurdistan, Iran. Dependent variables is occurrence and non-occurrence of rock...

Local protection against mountain hazards – state of the art and future needs

During the last decades, settlement activities increased in European mountain regions. Due to the scarceness of areas suitable for development, residential estates were extended into areas endangered by natural hazards such as mass movements. These settlements generally show a considerable vulnerability to tangible assets. Integral risk management strategies to reduce the vulnerability to tangi...

The Relationship Between Geology and Landslide Hazards of Atchison, Kansas, and Vicinity

Landslides along the Missouri and Kansas rivers will affect existing structures and potential development in the Kansas City metropolitan area. A pilot landslide-mapping project was conducted in the vicinity of Atchison, Kansas, to inventory existing landslides and determine the factors that caused them. Landslides are generally controlled by the slope morphology, geology, soils, and moisture c...

Proposed Research Plan Perchlorate Salt Effect on Rock Weathering on Mars at Phoenix Landing Site

The Phoenix Mission was the first to land in the polar regions on Mars. The mission revealed three surprising results: (1) The surface at the landing site had a very low concentration of large size rocks, (2) The unexpectedly sticky nature of the soil prevented it initially from falling through one of the instrument’s screens as planned, (3) Perchlorate salt was found at a high concentration (~...
