Effect of hydraulic properties of soil and fluctuation velocity of reservoir water on landslide stability

Abstract: Water fluctuation is the main triggering factor of reservoir slope failures, especially in the area of the Three Gorges Reservoir of China. Fluctuation velocity of reservoir water and hydraulic properties of soil as defined by soil-water characteristic curve (SWCC), saturated permeability coefficient and unsaturated permeability function are key potential properties that control reservoir landslide stability. The effect of reservoir water fluctuation velocity and hydraulic properties of soil on landslide stabi… Show more

“…Landscape resilience and stability are affected by the soil system which is in turn affected by the inherent balance between inputs and losses of nutrients and carbon [62]. Indicators assessing resilience of production functions include soil health variables such as total and mineralizable N and total C [113], soil organic matter [114], mineral P and K [115], pH and cation exchange capacity [116], soil physical properties [117], texture [118], structural stability [119], and soil-water relations. Work [120] has proposed a system evaluating sensitivity of land to degradation (ESAI) that combines soil properties with other factors (climatic, vegetation, and social]).…”

“…It is important to study the variations in the stability coefficient of the hydrodynamic pressure landslide for different permeability coefficients and increases in the rate of decline in the reservoir water level. In this study, the rate of decrease of the stability coefficient (RDSC) is used [20]. RDSC donates the rate of decrease in the stability coefficient of a hydrodynamic pressure landslide for a certain permeability coefficient when the rate of drawdown of the reservoir water level changes from 0.6 m/d to 1.2 m/d.…”

“…As a result, the landslide stability coefficient varies based on changes in the reservoir water level and saturated permeability coefficient [13,[16][17][18][19]. Notably, some studies have shown that the seepage fields and stability coefficients of reservoir landslides in the TGRA are affected by fluctuations in the reservoir water level [20][21][22][23][24]. Furthermore, Xiang, et al [25] studied the stability coefficient of a hydrodynamic pressure landslide affected by reservoir water level fluctuations; Chen and Liu [26] studied the seepage field and stability coefficient variations of a reservoir landslide in the TGRA based on different permeability coefficients; and Hsu and Chien [27] studied the landslide stability coefficient under extreme climates.…”
