Tidal Flooding

Tidal Flooding Latest News

Recently, the Kerala government declared tidal flooding as a state specific disaster.

About Tidal Flooding

• Tidal flooding, also known as sunny day flooding, king tide flooding, and nuisance flooding, is the temporary flooding of low-lying areas near a coast.
• Causes: It usually occurs through the combination of winds, offshore storms, and full moon cycles during high tide events such as full moons and new moons. 
• Unlike cyclone-induced storm surges, tidal flooding happens twice in a day and is more severe during full or new moons.
• Impact on Kerala Coast: It is a common phenomenon along Kerala’s coastline, where the Arabian Sea level temporarily rises above an identified threshold for a brief period, inundating low-lying coastal areas.

Kerala Government’s Decision

• Kerala government declared financial assistance, similar to that provided to victims of natural disasters under State Disaster Response Fund (SDRF), to victims of floods caused by tidal rise.
• This is the first time in the country that a State has declared tidal flooding a State-specific disaster.
• Other State-specific disasters in Kerala: Coastal erosion, lightning, strong winds, soil piping, heatwave/sunstroke/sunburn, and human-wildlife conflict as State-specific disasters.
