Ice-driven creep on Martian debris slopes
[1] Accumulations of rocky debris at the base of bedrock escarpments on Mars have mean inclinations of 20 , well below the angle of repose ( 35 ). These inclinations decrease with increasing latitude, suggesting a climatic influence. We present evidence that these low inclinations are the result of gravitational creep driven by repeated deposition and sublimation of ground ice. We estimate the ...
متن کاملSeasonal flows on warm Martian slopes.
Water probably flowed across ancient Mars, but whether it ever exists as a liquid on the surface today remains debatable. Recurring slope lineae (RSL) are narrow (0.5 to 5 meters), relatively dark markings on steep (25° to 40°) slopes; repeat images from the Mars Reconnaissance Orbiter High Resolution Imaging Science Experiment show them to appear and incrementally grow during warm seasons and ...
متن کاملThe Physics of Debris Flows
Recent advances in theory and experimentation motivate a thorough reassessment of the physics of debris flows. Analyses of flows of dry, granular solids and solid-fluid mixtures provide a foundation for a comprehensive debris flow theory, and experiments provide data that reveal the strengths and limitations of theoretical models. Both debris flow materials and dry granular materials can sustai...
متن کاملSlope Length Effects on Soil Loss for Steep Slopes
cients. Normalizing to a unit plot of length 22.13 m, both the USLE and RUSLE use the equation Empirical soil erosion models continue to play an important role in soil conservation planning and environmental evaluations around L 5 (l/22.13) [2] the world. The effect of hillslope length on soil loss, often termed the where L is soil loss normalized to the 22.13-m-long slope length factor, is one...
متن کاملAnalysis of Rainfall-Induced Landslide on Unsaturated Soil Slopes
This paper investigates rainfall-induced landslides on partially saturated soil slopes using the 2011 Umyeonsan landslides at the center of Seoul, Korea. An integrated analysis of rainfall-induced landslide was carried out through laboratory tests, field tests, and numerical analysis. The results of comprehensive investigations in the Umyeonsan region demonstrate that landslide activity is clos...
