Climate change has led to rising sea levels and more frequent extreme weather events, increasing flood risks in low-lying coastal areas. Earthen dykes are engineering structures used to protect agricultural lands and human settlements against flooding and storm surges. However, in many regions, existing dyke dimensions have been deemed to be insufficient to protect these lands from future sea-level rise. The Bay of Fundy, located in Nova Scotia, Canada, is projected to experience some of the highest rates of sea-level rise and has the highest tidal range in the world. Dykes in Nova Scotia total 241 km in length with 70% of them classified as highly vulnerable to overtopping by 2050. Heightening of these dykes is essential, which requires geotechnical stability assessments of these dykes. This requires proper inputs of the soil strength, porewater pressure (PWP) conditions and tidal loadings, both before and after construction. Surprisingly there is little data on the PWP dynamics near and within these dyke structures. This study aims to monitor PWPs within an existing dyke system near Masstown, Nova Scotia over several months with installation of vibrating wire piezometers and compare the measured PWPs to tidal signals recorded in the vicinity of the dyke structure. It is hoped that a better understanding of the tidal signal transfer and related PWP response in the dyke can result in more informed understanding of subsurface properties and processes and ultimately lead to more effective geotechnical stability assessments.
