Abstract

The bottom friction factor, $f_{e}$ , estimates for computing wave bottom frictional dissipation in Gon et al. (2020, https://doi.org/10.1029/2019jc015963), titled Wave Dissipation by Bottom Friction on the Inner Shelf of a Rocky Shore, are too large by a factor of 2 due to an error in the formulations by Thornton and Guza (1983, https://doi.org/10.1029/jc088ic10p05925), titled Transformation of Wave Height Distribution. Corrected formulations reduce the prior overestimation of the bottom friction coefficient, $f_{e}$ , which is more significant for rougher bottom surfaces, such as coral reefs and rocky shores, than for sandy beaches.

更新影响岩岸和珊瑚礁的摩擦系数公式

由于 Thornton 和 Guza（1983，https://doi.org/10.1029/jc088ic10p05925）在计算波高分布时的公式错误，Gon 等人（2020，https://doi.org/10.1029/2019jc015963）在计算波底摩擦耗散时估计的波底摩擦系数 f e ${f}_{e}$ 过大了 2 倍。修正后的公式减少了对底部摩擦系数 f e ${f}_{e}$ 的先验高估，这对珊瑚礁和岩石海岸等较粗糙的底面比对沙滩更为重要。
