every year, a considerable portion of the national budget specifies to reconstruct the properties which have been destroyed during natural disasters in iran. recognition of vulnerable sites to natural disasters can reduce the probable damages. the most important point in designing railway tracks is to join stations in the least possible time. so, the railway track is meant to cross lots of vall...

Industrially utilized river basins are frequently exposed to contaminants originating from polluting activities. However, the physical instability and probability of mass movement mobilization of contaminated soil into rivers have only received little attention. In this study, we present a GIS-based method to produce a regional overview of where and how contaminated areas are potentially expose...

The Sharm El-Sheikh/Ras-Nasrani area is one of the most attractive tourist resorts in Egypt particularly and in the world in general. The area has been rapidly growing during the last few years. Many construction projects including villages, hotels, beaches, and roads have recently been undertaken. The following study demonstrates the use of high-resolution satellite images, QuickBird imagery, ...

Creep is an important factor of muddy submarine channel slope instability. In this study, a sub-bottom profiler was used to monitor the continuous internal change in laboratory better understand creep characteristics and mechanism The process analyzed according changes sound intensity. results indicate notable during instability process. Changes intensity time series decrease with increasing de...

Slope instability triggered by rainfall is common in tropical countries like India, where the soil of hill slopes are generally unsaturated condition, having higher strength than saturated condition due to matric suction. This study aims investigate change pore water pressure (PWP) with infiltration into slope and corresponding effect stability on different from regions India. By applying surfa...
