Synthetic Aperture Radar Interferometry (InSAR) is an established powerful technique for change detection. Its advantages include competitive spatial resolution, accuracy in milimeter-centimeter scale and spatial coverage. However, there are limitations in using it for detecting the Earth surface changes. Line-of-sight ambiguity (1-D displacement), temporal and geometrical decorrelation (slopes...

Abstract The number of large landslides in India has risen the recent years, due to an increased occurrence extreme monsoon rainfall events. There is urgent need improve our understanding moisture-induced landslide dynamics, which vary both spatially and temporally. Geophysical methods provide integrated tools monitor subsurface hydrological processes unstable slopes at high spatial resolution....

[1] We study channelization and slope destabilization driven by subsurface (groundwater) flow in a laboratory experiment. The pressure of the water entering the sand pile from below as well as the slope of the sand pile are varied. We present quantitative understanding of the three modes of sediment mobilization in this experiment: surface erosion, fluidization, and slumping. The onset of erosi...

a r t i c l e i n f o Multi Temporal Interferometry (MTI) stands for advanced synthetic aperture radar differential interferometry (DInSAR) techniques, which include Permanent/Persistent Scatterers Interferometry — PSInSAR™/PSI and similar methods, as well as Small Baseline Subset — SBAS and related/hybrid approaches. These techniques are capable to provide wide-area coverage (thousands of km 2...

The paper discusses operations aimed at creating a safer natural or man made rock slope by artificially inducing the displacement of unstable elements by blasting. A detailed analysis of the problems with the use of explosives present when conducting these activities is carried out focusing on the advantages and disadvantages of this technology. The results of two examples of demolition of inst...

Major reforestation programs have been initiated on hillsides prone to erosion and landslides in China, but no framework exists to guide managers in the choice of plant species. We developed such a framework based on the suitability of given plant traits for fixing soil on steep slopes in western Yunnan, China. We examined the utility of 55 native and exotic species with regard to the services ...

Water chemical analysis of 100 springs from the Orco and the Tinée valleys (Western Italy and Southern France) and a 7 year groundwater chemistry monitoring of the 5 main springs were performed. All these springs drain from crystalline rock slopes. Some of these drain from currently active gravitational slope deformations. All groundwaters flowing through presently unstable slopes show anomalie...
