Topographic development in mountainous landscapes is a complex interplay between tectonics, climate and denudation. Glaciers erode valleys to generate headwall relief, and hillslope processes control the height and retreat of the peaks. The magnitude-frequency of these landslides and their long-term ability to lower mountains above glaciers is poorly understood; however, small, frequent rockfal...

Korea is topographically and meteorologically prone to natural disasters. In addition to extraordinary weather, localized heavy rain is a irregular occurrence. Highway in Korea are frequently damaged by rain, wind, flood, etc. Recently, slope failures are disastrous when they occur in mountainous area adjoining highways. The accidents associated with slope failures have increased due to rapid u...

Sikkim, a mountainous state in the Himalayas joined the democratic mainstream of the Indian Union in 1975. It has made enormous progress in planned economic development since then. Mountainous terrain and lack of reliable transportation and infrastructure does not allow establishments of large scale industries. Agriculture, dairy farming and cottage industries have limited scope of expansion. H...

The project named “the rescue system and key technology of high-speed railway in perilous mountains” primarily focuses on current railway constructions and operations in China. To state the relationship between risk events and risk factors, we classified the risk sources of operating tunnels of high-speed railway in perilous and mountainous area and established a hierarchical assessment system ...

This manuscript is the result of research conducted towards the production of meta-data to be used as inputs to neural networks. It is essentially a preliminary attempt towards the use of an evolutionary approach to interpret the significance which time series data pose on the behavior of mountainous water supplies, proposing a model which could be effectively used in the estimation of the aver...

Life in mountainous, rural areas poses unique obstacles for ophthalmic care--notably, a lack of access to ophthalmologists and cost of care. Using telemedicine as a screening tool addresses both issues for diabetic retinopathy (DR) screening, as fundus photography has been determined to be sensitive and specific when screening for DR. The American Diabetes Association places a Grade E recommend...

Driver expectation is about driver’s objective response and expectation for various traffic environments. It might directly influence the driving safety and traffic operation. This paper discusses in enough detail the shaping mechanism of driver expectation while considers road geometer parameters, driver behavior and vehicle performance in mountainous road. Combined various geometer parameters...

Schistosomiasis japonica has long been endemic in the People's Republic of China. In the 1950s, the number of the infected persons was estimated at 10 million; infected snail habitats were estimated at more than 14 billion square metres and infected cattle at 1.2 million. After schistosomiasis control measures were carried out, it was a great success. According to the survey of 1989, infected p...

Vegetation height is one of the leading dimensions of ecological variations among tree species and is central to ecosystem functioning [1]. Since its launch in 2003, GLAS (Geoscience Laser Altimeter System) on board ICESat (Ice, Cloud,and land Elevation Satellite) has produced unprecedented dataset at the global scale [2]. However, the challenge to retrieve canopy height from large-footprint sa...

Based on the precipitating factors of geological disasters in complex mountainous regions, this paper took geological disaster distribution, seismic intensity, fracture, engineering petrofabric, river distance, slope and precipitation as the risk indicators of geological disasters. Next, a mathematical model was established by using the analytical hierarchy process. The weight of above seven ri...
