Kerala has been bearing the brunt of the coastal flooding circular the year, with tidal waves advancing to the shoreline beyond the High Tide Line (HTL) which is the legally defined coastal enactment determined utilizing precise technological methods arsenic per the Coastal Regulation Zone (CRZ) notification. The contented becomes superior erstwhile thecoastal flooding coincides with outpouring tides, exacerbating the extent and grade of the flooding. According to a elder authorities officer, the hazard is peculiarly terrible successful low-lying regions successful Alappuzha and Ernakulam.

According to a authorities order, since tidal emergence is simply a regular earthy phenomenon, a mean tidal emergence cannot beryllium declared a catastrophe nether State Disaster Response Fund (SDRF) norms, making it hard to supply fiscal assistance to those affected nether the norms of the SDRF.

Due to deficiencies successful onshore use, a important fig of houses and structures are located successful floodplains, lands adjacent to rivers, and poramboke lands adjacent the waterbodies. In addition, factors specified arsenic siltation and reduced extent of rivers and lakes aggravate the flooding, which is present occurring during tidal emergence successful a mode not antecedently experienced, said the officials.
Unlike rainfall-induced flooding, tidal flooding is simply a hazard that tin hap passim the year, which further enhances the relevance of declaring it a State-specific disaster, stated the authorities order. With the declaration, fiscal assistance, akin to that provided to earthy catastrophe victims nether the SDRF norms, could beryllium granted to victims of coastal high-tide flooding/sea incursion.
