Storm Surge

Damage to life and property due to tropical storm-induced storm surges occur as a result of the inundation of low-lying lands in the shore. Storm surge is primarily originated by pressure induced on ocean surface by high winds resulting in an unusual rise in water level causing coastal flooding.

A statistical analysis of past storm surges was performed to derive cyclone scenarios with respective   recurrence intervals for the purpose of storm surge hazard assessment.

The probable extent of onshore inundation due to the range of tropical storms was not conducted due to lack of good quality data for input to a multi-scenario analysis using the MIKE21 Flow Model. The model uses a depth­averaged, non-linear    equations of conservation of mass and momentum to simulate tropical storm induced storm surges.

The model uses a depth­averaged, non-linear    equations of conservation of mass and momentum to simulate tropical storm induced storm surges. The storm surge hazard profile is intended for coastal disaster risk mitigation planning, evacuation planning and public education and awareness. Due to uncertainties associated with modelling the hazard profile is derived using expert judgment. Limitations of the study as well as recommendations for improving the storm surge hazard maps are provided as on output of this study.
