Table 1 Percentages of coastlines showing positive trends in wave and surge parameters, and of sandy shorelines showing recession for world and continent coastline. For \(\Delta C_{D}\) only absolute values between 1 and 5 m/year considered, with values outside these limits being excluded from the percentage calculations.
Sandy shoreline recession \(\Delta C_{D}\) | Increasing trend of \(\Delta C_{g} E\) | Increasing trend of \(\Delta H_{s}\) | Increasing trend of \(\Delta H_{s}^{95}\) | Increasing trend of \(\Delta N_{{H_{s}^{95} }}\) | Increasing trend of \(\Delta T_{m}\) | Increasing trend of \(\Delta \eta^{95}\) | Increasing trend of \(\Delta N_{\eta 95}\) | ||
