ABSTRACT

Slope failures and shallow landslides occur due to shallow subsurface flow convergence, soil saturation and shear strength reduction following a heavy rainfall. The semi-arid environment of southern Arizona (AZ) experiences a significant increase in precipitation during the summer. As a result, the soil moisture increases the potential for slope failure due to water table fluctuation and pore pressure escalation. In this paper, the relationship between soil moisture distribution and topography information (slope angle, topography wetness index) is examined using the topography wetness index, NASA's Shuttle Radar Topography Mission (SRTM) images and cokriging. Using the Digital Elevation Model (DEM) generated from remote sensing images, the slope stability analysis is performed in a typical semi-arid environment area using data from the Waternut Gulch Experimental Watershed in Tombstone, AZ. Conclusions and future research are provided at the end of the paper.
