Variation in design conditions in response to sea-level rise

Variation in design conditions in response to sea-level rise

In assessing the potential impacts of sea-level rise, much of the work to date has focused on the outcome of specific sea-level rise scenarios. For shoreline management, we are, however, interested in not only the net change for a given scenario but also how and at what rate the change takes place. The complex range of interactions on the coast, coupled with different rates of response and the existence of thresholds make this a particularly difficult task. The alternative is to look at how the key parameters are changed and to use these to evaluate the interactions and hence the net change to the system as a whole. In this study, consideration has been confined to the key parameters for coastal engineering design. The approach adopted considers the relative change in each parameter as a function of the relative change in water depth. As a consequence, the results are quite general and enable some broad conclusions to be drawn on the implications for shoreline management.

Abstract

In assessing the potential impacts of sea-level rise, much of the work to date has focused on the outcome of specific sea-level rise scenarios. For shoreline management, we are, however, interested in not only the net change for a given scenario but also how and at what rate the change takes place. The complex range of interactions on the coast, coupled with different rates of response and the existence of thresholds make this a particularly difficult task. The alternative is to look at how the key parameters are changed and to use these to evaluate the interactions and hence the net change to the system as a whole. In this study, consideration has been confined to the key parameters for coastal engineering design. The approach adopted considers the relative change in each parameter as a function of the relative change in water depth. As a consequence, the results are quite general and enable some broad conclusions to be drawn on the implications for shoreline management.
