Adaptability of flood embankments to climate change
Adaptability of flood embankments to climate change
In the context of growing concerns about climate change affecting precipitation patterns, there is a need to incorporate these changes into the design of flood defenses, particularly earthfill embankments. Although numerous geotechnical modeling techniques have improved understanding of soil embankment behavior, uncertainty regarding the impact of climate change to embankment performance still remains. Research in this field aims to identify instabilities that potentially could occur throughout an embankments lifecycle, and development of corresponding solutions. Geotechnical modeling techniques and site-specific precipitation pattern projections, establish a comprehensive analysis framework, which allows assessing long-term behavior and resilience to a changing climate of existing and new embakments. The paper provides an overview of the climate-driven processes that are of greatest concern for hydro-mechanical behavior of earthfill flood embankments. Then, key aspects that need to be considered for predictive computational modeling, which combines geotechnical and climate modeling, are presented. Finaly, various strategies for embankment adaptation in order to improve their resilience to climate change are given.
