ABSTRACT
In this chapter, we investigate how remote sensing can support coastal flooding risk assessments. In this context,
hazard is defined as the product of the intensity and frequency of coastal flooding during extreme events,
while risk considers the vulnerability of exposed populations, activities, and assets. We first assess the required
information for coastal flooding hazard assessment (Sect. 2), then focus on specific contributions of SAR interferometry
for monitoring coastal subsidence and infrastructure stability, the failure of which potentially causing flooding of
nearby areas (Sect. 3). In Sect. 4, we discuss current challenges and opportunities in using remote sensing to
support decisions in the field of coastal flooding and infrastructure stability.
