The purpose of this paper is to analyze the relationship between climate change and the need to rehabilitate sea dykes. Sea dykes are a critical component of coastal infrastructure and national flood prevention systems and are increasingly susceptible to a number of failure mechanisms under climate change conditions. This paper will explore case studies of sea dyke rehabilitation and climate change in both the Netherlands and Japan. Both countries have urban areas within close proximity to coastal areas and have constructed sea and river dykes as part of their national flood prevention plans. The International Panel on Climate Change published a report in February 2012 stating that mean global temperatures are going to increase by 1 to 3 degrees Celcius by 2050, which will affect global weather conditions. The characteristics of climate change which most affect sea dykes include the frequency and severity of storms as well as global sea level rise. These trends increase the risk of dyke failure modes such as overtopping, micro instability, and erosion of non-reinforced inner slopes. Techniques for rehabilitation both proven and proposed will be discussed with a particular focus on methods for implementation as well as the policy framework of these projects.
