Tue, May 11, 20 21 9:30 PM - 11:00 PM EDT |
By Dr. Cheryl Hapke
Along the Big Sur coastline in ce ntral California where weak rocks and steep topography provide ideal condit ions for frequent large landslides that potentially contribute a substantia l portion of material to the littoral sediment budget. Little was known abo ut the sediment budget in this area, including the amount, rate and frequen cy of sediment input to the system from coastal landslides. Adjacent to the Big Sur coastline is the Monterey Bay National Marine Sanctuary (MBNMS), a nd the California Department of Transportation (Caltrans) needed solutions to the difficulties they face with keeping slide-prone coastal Highway 1 op en and safe while minimizing impacts to the MBNMS below the road. As a cont ribution to developing a highway management plan, and in order to advance t he fundamental understanding of landslide and coastal processes along this stretch of coastline, an approach was developed to quantify the historical volume of sediment that enters the littoral system from coastal slope failu res. This presentation will tell the story of landslides, coastal processes , highway management and natural resource protection and the science that t ies them together.
