Coastal Erosion Affected Tuticorin Coast And Not Heavy Mineral Mining

Coastal erosion is a natural phenomenon that cannot be disregarded or discounted. S Vaikundarajan throws light on the many reasons that can cause a shoreline in any part of the world to erode and succumb to natural and environmental changes rather than man made interventions like heavy mineral mining.

Vaikundarajan VV Mineral India says, “Coastal erosion is the wearing off of beach by wave action, drainage or high winds, tidal currents and or wave currents. Waves, generated whether by storms, winds, or fast moving motor crafts, cause coastal erosion.”

Such occurrences cause long-term loss of sand and rocks or a temporary redistribution of coastal sands in one location to another.

“Depending on whether the beach is sandy or rocky the erosion patterns will vary. Varying types of coastlines have varying types of erosion patterns”, says Vaikundarajan

A softer beach with sandier sediments causes that beach to erode easily. However, if a beach is rocky then it may cause in what is called beach expansion since the wave action converts rocks to sediments and then to sand.

Thus, rocky beaches seem to expand and soft sandy beaches seem to erode over long periods of time. The erosion of a coastline also depends on how much water the sand can hold. If a sandy beach does not restore water then more and more sand is washed off such a beach.

Thus Vaikundarajan concludes that VV Mineral India’s heavy mineral mining alone cannot be held responsible for the beach erosion caused on the Tuticorin coastline.
