“…Theoretically, vulnerability is defined as the extent of the susceptibility of the people, resources, and environments to the impacts of particular hazards which is determined by physical, social, economic, and environmental criteria (UNDRR 2009). Remote sensing data coupled with spatial analysis provides an efficient approach to assess the spatial tropical cyclone vulnerability (Hoque et al 2017;Rao et al 2013;Yin et al, 2013). Several criteria, directly and indirectly, influence the tropical cyclone vulnerability for any area (Mansour 2019).…”

“…A vast amount of data in the form of spatial and non-spatial are required to evaluate the influence of criteria in the tropical cyclone vulnerability assessment (Mansour 2019). Several mapping approaches have been used for assessing spatial tropical cyclone vulnerability using geospatial techniques (Ali et al 2020;Hoque et al 2019;Mazumdar and Paul 2018;Rao et al 2013). Multi-criteria integrating mapping techniques are considered best as these provide detailed spatial vulnerability information of tropical cyclone impacts (Alam et al 2020;Ali et al 2020).…”

Abstract. The present work describes the interaction between waves and currents utilizing a coupled ADCIRC+SWAN model for the very severe cyclonic storm Hudhud, which made landfall at Visakhapatnam on the east coast of India in October 2014. Model-computed wave and surge heights were validated with measurements near the landfall point. The Holland model reproduced the maximum wind speed of ≈ 54 m s −1 with the minimum pressure of 950 hPa. The modelled maximum surge of 1.2 m matches with the maximum surge of 1.4 m measured off Visakhapatnam. The two-way coupling with SWAN showed that waves contributed ≈ 0.25 m to the total water level during the Hudhud event. At the landfall point near Visakhapatnam, the East India Coastal Current speed increased from 0.5 to 1.8 m s −1 for a short duration (≈ 6 h) with net flow towards the south, and thereafter reversed towards the north. An increase of ≈ 0.2 m in H s was observed with the inclusion of model currents. It was also observed that when waves travelled perpendicular to the coast after crossing the shelf area, with current towards the southwest, wave heights were reduced due to wave-current interaction; however, an increase in wave height was observed on the left side of the track, when waves and currents opposed each other.

“…Linear wave theory of vertically sheared weak current is also discussed using both perturbation and numerical methods (Kirby and and Tsung-Muh, 1989;Dong and Kirby, 2012). When waves propagate through strong currents, their characteristics change with refraction, bottom friction and blocking (Kudryavtsev et al, 1999;Ris et al, 1999). Also, the mean flow will be affected by the addition of momentum and mass fluxes.…”

Abstract. The present work describes the interaction between waves and currents utilizing a coupled ADCIRC + SWAN model for the very severe cyclonic storm Hudhud which made landfall at Visakhapatnam on the east coast of India in October 2014. Model computed wave and surge heights were validated with measurements near the landfall point. The Holland model reproduced the maximum wind speed of &approx; 54 m/s with the minimum pressure of 950 hPa. The modelled maximum surge of 1.2 m matches with the maximum surge of 1.4 m measured off Visakhapatnam. The two-way coupling with SWAN showed that waves contributed &approx; 0.25 m to the total water level during the Hudhud event. At the landfall point near Visakhapatnam, the East India Coastal Current speed increased from 0.5 to 1.8 m/s for a short duration (&approx; 6 h) with net flow towards south, and thereafter reversed towards north. An increase of &approx; 0.2 m in Hs was observed with the inclusion of model currents. It was also observed that when waves travelled normal to the coast after crossing the shelf area, with current towards southwest, wave heights were reduced due to wave-current interaction; however, an increase in wave height was observed on the left side of the track, when waves and currents opposed each other.
