The concept is widely used for estimating sediment budgets, numerical models of coastal change, beach nourishment design and disposal of dredged material. With recent interest on climate change impact assessments on coasts, the Bruun (1962) rule, in which DoC is a key parameter, is often used for future beach loss analysis (e.g., Udo and Takeda, 2017); However, the determination of DoC, especially in the absence of repeated profile measurements, is one of the controversial issues in employing the Bruun rule for such impact assessments for decision making (e.g., Ranasinghe et al., 2012).
