“…The impact of wave-tide interactions in modulations of wave height on the west coast of India (of Mumbai) was studied by Sirisha et al (2023) wherein it was found that in order to improve the simulation accuracy, wave-tide interaction should be incorporated. Performance of ERA-5 wind data in the simulation of storm surge, wave-current interaction for Ockhi cyclone was evaluated by Samiksha et al (2023) wherein it was found that a coupled hydrodynamic wave model forced with ERA-5 wind is able to simulate storm surge, wave climate, etc. The numerical model MIKE-21 SW forced with ERA-5 wind was used by Sirisha et al (2017) to evaluate the accuracy of an operational weather forecast system at ESSO-INCOIS during extreme events and calm weather conditions in the north Indian Ocean.…”

The development of coastal roads and bridges is important to overcome traffic congestion in densely populated coastal cities like Mumbai. In the present study, the importance of assessment of wave conditions required for the extension of jetties to facilitate the transportation of bridge components to build the sea link bridge during non-monsoon season is envisaged so that zero downtime for operability at jetties is ascertained. Coupled hydrodynamic spectral wave model (Telemac-2D and TOMAWAC) used to hindcast waves reveals that the application of spatio-temporal varying 2D directional spectrum (from ERA-5) over the offshore boundary as a forcing function helps in propagation of realistic wave climate of Mahim Bay, Mumbai. Coupling of the TOMAWAC-ARTEMIS model is essential to obtain reliable wave conditions near the jetties (nearshore) for predominant directions. The study reveals that under existing conditions, downtime at proposed jetties will be for 30 days wherein Hs ≥ 0.3 m. As such to achieve zero downtime, the existing bund on the seaward side of jetties was extended optimally (70 m) so that smooth operability for the entire non-monsoon is achieved. Thus, application of spatio-temporal varying 2D spectrum in optimising the length of the guide bund has been found promising for speedy transportation of proposed bridge components. The study also reveals that there is an insignificant climatological impact on wave conditions.

“…This finding suggests that using a hybrid wind field could improve future typhoon storm surge predictions and preparations. Samiksha [18] investigated the performance of ERA5 winds on computed storm surges and wave-current interactions during the Ockhi cyclone. They found that the ERA5-forced model produced more accurate results in generating waves during the cyclone compared with the standalone model.…”

With global climate warming, the frequency and intensity of typhoons are increasing, highlighting the significance of studying storm surges for coastal engineering disaster mitigation. In this study, we assessed the predictive capabilities of the new ERA5 reanalysis model and the traditional Fujita−Takahashi model for storm surges. We found that the traditional Fujita−Takahashi model, utilizing a prelandfall typhoon wind field, exhibited higher accuracy in storm surge predictions, while the ERA5 reanalysis model, employing a postlandfall wind field, demonstrated superior performance. By considering the strengths and weaknesses of both wind field models and analyzing the impact of Typhoon In-fa (2021) on the East China Sea, we determined the influence of this typhoon on storm surge heights along the eastern coastal region. These research findings provide valuable insights for the development of effective protection strategies, offering valuable references for coastal resilience planning.
