Dependency of the proportional constants and the standard deviation of the log-scaled residual errors to the parameter r. The depth at a coastal station was defined as the average depth within r from the station along the waterway (see Section 3). (a) The relationship between r and a (Eq. (4)) is plotted. (b) The relationship between r and standard deviation of residual error of log10Hc is plotted. Residual errors are measured by the difference of log10Hc between by the coastal observation data and the calculated values by regression functions (Eqs. (6) and (7)).
