Abstract: The Advanced circulation model has been used for the simulation of storm
surges and inundation along the east coast of Indian states Odisha and Andhra
Pradesh for tropical cyclones Phalin and Hudhud which made landfall on 12
October 2013 and 2014 respectively. Time series analysis of the cyclonic events
(1990-2016) has been carried out using Mann Kendall (MK) test to see the trend
of cyclones in the east coast. The result shows declining trend in cyclones and
cyclonic disturbances except severe cyclones, which shows existing of no trend.
The ADCIRC model results for two selected cyclones simulate the storm surge
height 2.8 m and 1.7 m respectively for Odisha and Andhra Pradesh coast. The
results were calibrated with observation station situated at Gopalpur port. In
addition to this, entire study area was categorised and classified on the basis of
storm surge height to prepare vulnerability risk map to look into the inundation
extent. Inundated area in Odisha coast has come out to 1649 km2 and 360 km2
for Andhra Pradesh coast. The results were in good agreement with the
regression value of R2 = 0.94 for a complete tidal cycle.
