“…It increases the soil volume and compaction and decreases the pores which will be more vulnerable to vehicles. This finding is similar to that of Feiznia et al (2001) and Coe et al (2003). The liquid index and plastic index and soil moisture have proved the reasons of soil movement and changes from plastic to liquid phase.…”

Hosseini S.A.O., Shahroodi E.F., Lotfalian M., Parsakhoo A. (2017): Evaluating the effect of biological stabilization on landslide control at the edge of forest road. J. For. Sci., Landslide is one of the negative sides of building non-standard roads in forest areas. The aim of the present study was to assess the effect of biological stabilization on landslide at the edge of forest roads in south and north aspects. For this purpose, in Neka forest (Mazandaran province) three treatments including control, sliding and stabilized areas covered by 35-years-old even-aged alder trees were selected. Benchmarking and soil sampling were conducted during three periods including July, November after rainfall events and March after rainfall events. The results showed that the mean movement of landslide in north direction was 9 cm, while this value was 6 cm in south direction. Sliding in north direction was 32% more than that in south direction. Biological stabilization by alder in north and south direction caused a 33 and 66% reduction in landslide movement, respectively. The characteristics of soil mechanics were different between stabilized and sliding areas. Besides, the soil texture in north direction for control and stabilized areas was clay with high liquid limit (CH) and for sliding area it was clay with low liquid limit, while this value in south direction was CH for three treatments of control, stabilized and sliding areas. To plan biological stabilization, the mechanical characteristics of soil, site features, and appropriate plant species should be considered as important factors.

“…The active part of this landslide is about 3.9 km long, and its widths range from 100 m to 500 m [45]. The surface elevation of the landslide ranges from 2750 m to 3650 m [46,47]. The great altitude difference causes the continuous sliding for hundreds of years.…”

An Adaptive Offset Tracking Method with SAR Images for Landslide Displacement Monitoring

et al. 2017

Abstract:With the development of high-resolution Synthetic Aperture Radar (SAR) systems, researchers are increasingly paying attention to the application of SAR offset tracking methods in ground deformation estimation. The traditional normalized cross correlation (NCC) tracking method is based on regular matching windows. For areas with different moving characteristics, especially the landslide boundary areas, the NCC method will produce incorrect results. This is because in landslide boundary areas, the pixels of the regular matching window include two or more types of moving characteristics: some pixels with large displacement, and others with small or no displacement. These two kinds of pixels are uncorrelated, which result in inaccurate estimations. This paper proposes a new offset tracking method with SAR images based on the adaptive matching window to improve the accuracy of landslide displacement estimation. The proposed method generates an adaptive matching window that only contains pixels with similar moving characteristics. Three SAR images acquired by the Jet Propulsion Laboratory's Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR) system are selected to estimate the surface deformation of the Slumgullion landslide located in the southwestern Colorado, USA. The results show that the proposed method has higher accuracy than the traditional NCC method, especially in landslide boundary areas. Furthermore, it can obtain more detailed displacement information in landslide boundary areas.

“…Guerriero et al, 2015). Slow movement is normally concentrated along lateral-slip surfaces (Fleming and Johnson, 1989;Gomberg et al, 1995;Coe et al, 2003;Guerriero et al, 2016) which consist of fault-like segments (e.g. Segall and Pollard, 1980) locally associated with cracks arranged in en echelon sets (Fleming and Johnson, 1989).…”

“…Iverson, 2005;Grelle et al, 2014). Thus, most earth flows move faster during periods of high precipitation or snowmelt than during drier periods, and the correlation between precipitation and velocity is normally complex (Coe et al, 2003;Schulz et al, 2009). Earth flow surges can occur when prolonged rainfalls are associated with the loss of efficient drainage pathways (Handwerger et al, 2013) and new sediment becomes available in the source zone through retrogression of the upper boundary (e.g., Guerriero et al, 2014).…”

Abstract. Continuous monitoring of earth flow displacement is essential for the understanding of the dynamic of the process, its ongoing evolution and designing mitigation measures. Despite its importance, it is not always applied due to its expense and the need for integration with additional sensors to monitor factors controlling movement. To overcome these problems, we developed and tested a low-cost Arduino-based wire-rail extensometer integrating a data logger, a power system and multiple digital and analog inputs. The system is equipped with a high-precision position transducer that in the test configuration offers a measuring range of 1023 mm and an associated accuracy of ±1 mm, and integrates an operating temperature sensor that should allow potential thermal drift that typically affects this kind of systems to be identified and corrected. A field test, conducted at the Pietrafitta earth flow where additional monitoring systems had been installed, indicates a high reliability of the measurement and a high monitoring stability without visible thermal drift.
