A robust surface matching technique for integrated monitoring of coastal geohazards

At the dynamic coastal fringe, numerous processes interact with local morphology. In
soft-cliff environments, this can often lead to the occurrence of coastal geohazards. These
can pose a major threat to property and cultural heritage, and an effective monitoring
strategy is therefore essential. While contemporary monitoring techniques have been
applied, these are often unsuitable in isolation. This paper presents an integrated
approach, with the development ofweighted surfacematching software enabling reliable
dataset fusion and multi-temporal change detection, even where significant surface
differences exist. Evaluation of this approach is presented and discussed.
