• Abstract:
  Climate change, along with the associated shifts in weather patterns, is projected to adversely impact the weather-related deterioration processes leading to exacerbated failures and/or shorter service life. Additionally, climate change is projected to increase the frequency of extreme precipitation events, leading to an increase in embankment failure potential. This study evaluated (1) the effect of future climate scenarios on the long-term performance of clay embankments, and (2) the effect of extreme precipitation events brought about by future climate scenarios on the hydromechanical response of clay embankments to these extreme events. The study area examined was Central Los Angeles, CA. A multi-phase hydromechanical geotechnical model was developed for exemplary high plasticity and low plasticity clay embankments with varied side slope angles. Overall, it was concluded that climate change is generally projected to adversely affect the performance of clay embankments both in the long-term and during extreme events.
