A Hillslope Stability Analysis by Use of Soil Characterization and Pore Pressure Measurements
The unique site of Antelope Valley River near Williams, California has for a few years been a place of interest and research because of the distinct sedimentary layering and the very regular pattern of hills and hollows. In the winter of 2017, a huge storm came through the site and induced four hundred landslides. Another storm then followed in the winter of 2019 at a much lesser degree of strength compared to the 2017 storm; however, it caused only about a hundred landslides, but all in new regions. The seemingly random nature of these slides has spiked my interests and pushed me to try to understand and to answer why some parts of the hills are failing, while others are not. I will be focusing on one hill in particular – Rhondas Hill – where a 2017 failure and a 2019 failure site lay side-by-side. To characterize and differentiate the regions where the land sliding occurred, this study will include pore pressure measurements of saturated soil, as well as soil samples at different points along the hillside.
