Modelling study of the equilibrium profiles formed on sandy coasts of different bed slopes and grain sizes under the various wave conditions was realized by using the CROSS-P and Xbeach morphodynamic models. A special criterion taking into account a total volume of bed deformations per one hour was suggested to determine the conditions of profile stabilization. For both models the time scales of equilibrium profile formation were found to be the same. However, the deformation magnitudes differed significantly. Bed deformations were computed on the whole profile length over the 200-hours duration of wave impact. It was concluded that both models predict a trend of the bed slope toward a stable value. CROSS-P model shows the widening of accumulative terrace during the profile evolution. The mean slope of the equilibrium profile was found to depend on the initial bed slope.
What innovative policy tools can be introduced so that the provision of local services will mitigate inequality among residents of different localities? Based on the ‘new localism’ approach, this article examines one such tool—a mandatory national standard for services provided by local authorities (a ‘service basket’)—and suggests that the implementation process should consider local variation and autonomy. The novelty of our approach lies in including both objective and normative considerations in the methodological instrument that we developed to capture these two dimensions. This innovative methodology also enabled us to estimate existing service gaps among local authorities and the burdens some will face upon instituting a mandatory service basket.
