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.

“…The 1989 Kavali cyclone that crossed the south Andhra Pradesh coast (30 km north of Kavali) on 8 November at 1900 UTC, resulted in a maximum surge (run-up height) of 4.0 m (ref. 15). The simulated maximum water level was about 2.6 m, and associated horizontal inundation varied from 1 to 3 km along the right of the cyclone landfall location.…”

“…The November 1996 Andhra cyclone resulted in maximum surge of about 3 m near Kakinada, and the extent of coastal flooding reported was about 3.0 km (ref. 15). The November 2000 Cuddalore cyclone resulted in storm surge varying from 1.2 to 1.5 m, with no inundation reported.…”

Coastal Inundation Research:An overview of the Process

Coastal inundation is the flooding of coastal zone resulting from increased river discharge, spring tides, severe storms, or generation of powerful waves from tectonic activity (tsunami). This article discusses the critical factors that contribute to coastal inundation. Among the probable factors that cause coastal flooding and destruction, storm surge is the most frequent, and hence this article provides a detailed evaluation of the progress made in storm inundation research. Recent advances in coastal inundation modelling include efforts to understand the nonlinear dynamic interaction of near-shore waves, wind and atmospheric pressure with still water sea level and coastal currents, and their combined effects on storm surge along the coast and interaction with coastal morphology. An advanced storm-surge model comprises different modules, viz. an atmospheric component, and two ocean components for surge and wave simulations; these modules are coupled with each other. The nesting of regional coastal model with an ocean-wide model captures the far-field boundary forcing of extreme events that usually originate from the warm open ocean. Even though significant advancements reported on the efficiency and accuracy of storm surge and inundation prediction, further studies are required to understand the nonlinear interaction of storm surge with coastal landforms and their vegetation (land cover). In the context of rising sea level, increased tropical cyclone activity and rapid shoreline change, it is pertinent to evaluate the future flooding risk associated with landfall of tropical cyclones in densely populated coastal cities.

“…ADCIRC (Advance CIRCulation) numerical model was applied along the GOM, Caribbean Sea and BoB (Blain et al 1994;Rao et al 2012). SLOSH and ADCIRC models along with parametric wind field models were extensively used for storm surge studies by Dietsche et al 2007;Cardone and Cox 2009;Melton et al 2009;Bunya et al 2010;Dietrich et al 2010 andNiedoroda et al 2010 in different oceanic basins.…”

“…A good number of storm surge studies have been documented for BoB (NIO) basin using monograms, empirical, theoretical and numerical methods (e.g. Ali 1979;Lwin 1980;Das et al 1983;Ghosh 1985;John et al 1983;Murty et al 1986;Flather 1994;Dube et al 2000Dube et al , 2004Rao et al 2012;Jain et al 2010).

Coupled ocean-atmospheric phenomenon such as tropical cyclones (TC's) is governed by geophysical fluid dynamics. TC associated strong wind stress transfer momentum energy to the ocean surface that acts as the prime mechanism in modulating the sea surface and in generating the storm surge. A primitive equation, Princeton ocean model (POM) with free surface, sigma (terrain-following) coordinates and realistic bottom topography is configured in Bay of Bengal (BoB) to simulate the storm surge/sea surface height (SSH) and surface currents during a super cyclone TC05B 1999. TC wind fields are developed by adopting a suitable formulation based on partial conservation of angular momentum. Modeled TC wind fields are superimposed with QuikSCAT Satellite/National Centre for Environmental Prediction (QSCAT/NCEP) blended ocean surface winds to drive the three-dimensional ocean model. Model simulated storm surge and SSH are compared with limited available surge estimates/observations and multi-satellite observed AVISO (Archive, Validation and Interpolation of Satellite Oceanography) SSH, respectively to evaluate its performance.
