On the Bruun Rule suitability for modelling shoreline change

| description | Modelling and understanding shoreline response to sea-level rise over decadal to
centennial timescales is crucial for managing sandy coasts. Globally, the Bruun Rule is
one of the most common shoreline model applied to facilitate this. However, there are
several limitations to the Bruun Rule, which can compromise coastal management
decisions. Here, we provide a novel assessment of the suitability of the Bruun Rule for
application in sandy coasts by applying it to hindcast and project shoreline change in
three morphologically different sandy beaches over yearly and decadal timescales. We
also compare the Bruun Rule predictions against associated observations, published
predictions from a hybrid shoreline model, and historical shoreline changes. Results show
that the Bruun Rule fails to accurately hindcast and provide realistic projections of future
shoreline change in sandy coasts. We attribute this to its assumption of linearity between
shoreline retreat and relative sea-level rise and its inability to account for nearshore
circulation. We, therefore, recommend limiting the use of the Bruun Rule for informing
policy and the management of sandy coasts. |
