Investigation on the effects of Bragg reflection on harbor oscillations

“…Harbor oscillations (also called harbor resonance or seiches) refer to the gathering and magnification of the incident wave energy inside bays or harbors, which can be triggered by atmospheric fluctuations, infragravity waves, tsunami waves, steady-state or transient wave groups, shear flows, or seisms (Bellotti, 2007;De Jong and Battjes, 2004;Fabrikant, 1995;Gao et al, 2017a;Gao et al, 2020;Kumar and Gulshan, 2017;Okihiro and Guza, 1996;Zheng et al, 2021). It may interrupt the operation of docks, create excessive movements of moored ships, cause unacceptable mooring forces, and even lead to the break of mooring lines (Gulshan et al, 2020;Kumar et al, 2016). The research progresses on harbor oscillations during the last three decades have been reviewed and summarized by Rabinovich (2009).…”

On hydrodynamic characteristics of transient harbor resonance excited by double solitary waves

“…It needs to be emphasized that it is of crucial importance to accurately estimate and comprehensively study these hydrodynamic characteristics. Both the evolution of the maximum free-surface elevation and the maximum runup are tightly correlated with the tsunami-triggered flood around the harbor area (e.g., Gulshan (2017, 2018); Gao et al (2016b;); both the wave energy distribution and the total wave energy offer vital information for accurately predicting the movement of ships in harbors (Gulshan et al, 2020).…”

“…Firstly, Gao et al (2018a) assumed the constant water depth inside the harbor. Nevertheless, for real harbors, their topographies are generally uneven (Gulshan et al, 2020;Kumar and Rupali, 2018). Therefore, in this article, more complicated bottom profiles are taken into consideration.…”

Study on Influences of Fringing Reef on Harbor Oscillations Triggered by N-Waves

“…If the period of the incident waves travelling from the ocean is close or equal to one of the eigenperiods of a semi-enclosed water body (such as a harbor), the water body will appear a longperiod violent fluctuation, which is normally referred to as harbor oscillations or harbor resonance or harbor seiching (Miles, 1974;Rabinovich, 2009). This phenomenon may lead to excessive responses of berthing vessels, which would significantly interrupt the loading/unloading operations of the ships and even break mooring lines and cause collision accidents (Kumar et al, 2016;Gulshan et al, 2020). Innumerous harbors all over the world have observed the phenomenon, such as Longkou Harbor (Wang et al, 1987), Hualien Harbor (Maa et al, 2011), Long Beach Harbor (Lee and Xing, 2009), Pohang Harbor (Kumar and Rupali, 2018;Kumar et al, 2014), Hambantota Port (Dong et al, 2020b) and Paradip Port (Rupali et al, 2020a, b), and huge economic losses and even casualties have been caused.…”
