The interaction between sedimentation/erosion and faulting represents one of the most intriguing topics in landscape tectonics evolution. Only few studies have been able to document feedback sedimentary loading from field observations. Here, we focus on how sediment loading/unloading influences dynamics fault systems Fucino basin, Central Apennines (Italy). basin a remarkable case study with re...

The present study shows that very low erosion class (0.23 to 8 tons per hectare per year) Romeshgan watershed, most of the area to be included in the attrition levels low, medium, large and have too much. In general we can say the area is low to moderate ability erodible. SLEMSA model for estimating erosion, environmental conditions are examined. These factors in watershed erosion rates in diff...

The Eel River draining the Coast Range of northwestern California has the highest recorded average suspended sediment yield per drainage area of any river of its size or larger unaffected by volcanic eruptions or active glaciers in the conterminous United States (1,720 t/kmyr from 9,390 km; Brown and Ritter, 1971). These high rates of erosion and sediment transport result from a combination of ...

High-speed trains with the maximum speed of 300 km/h, named as Korea Train Express (KTX), have started revenue services since April 2004. Because of the geomorphologic conditions of Korea a large portion of the ‘Kyung-Bu’ line is comprised of tunnels or bridges, which may cause excessive noise in a vehicle. The vibration generated by the trains propagates into the tunnel and the vehicle structu...

On 6 March 2015, Dawn arrived at Ceres to find a dark, desiccated surface punctuated by small, bright areas. Parts of Ceres' surface are heavily cratered, but the largest expected craters are absent. Ceres appears gravitationally relaxed at only the longest wavelengths, implying a mechanically strong lithosphere with a weaker deep interior. Ceres' dry exterior displays hydroxylated silicates, i...

The geotechnical behaviour of expansive clay soils is investigated by looking into the geomorphologic, geological and climatic conditions and mineralogical composition of the soils in the study area. The geotechnical results are linked with the performance of the foundation as well as structures. Since swell potential and swell pressure are key properties of expansive soils, the swell parameter...
