Description 89-95
This paper
reports the sensitivity and predictive capability studies carried out on the finite
element model for storm surge simulation
along the east coast of India. In this model, an explicit
finite element scheme with 9-noded Lagrangian

quadratic
isoparametric elements was used to discretize the study area and the governing
equations. The integration of dependent variables over an element was performed
using two-dimensional Simpson's rule, which leads to uncoupling of the system
of equations and yields an explicit scheme for determining the flow parameters
evolving with time. In the present work,

the model
has been benchmarked using an International software MIKE21. Sensitivity
studies are carried out to evaluate the influence of the length of the ocean
shelf and its depth at the coast in predicting the storm surges along the

coast. The results show that
the model is not sensitive to these parameters. Then the model is calibrated by
simulating the storm surges induced by the 1977- Andhra cyclone, which is one
of the severe cyclones in recent years along the east coast of India. The
predictive capability of the calibrated model is assessed by simulating the
surges for a few past cyclonic storms, which have crossed the east coast of India.
