Coastal Wetland Restoration: Concepts,
Methodology, and Application Areas Along
the Indian Coast
Ramasamy Manivanan
Abstract This paper emphasizes and endorses the use of natural restoration techniques for Coastal Wetland Restoration in Indian scenario. Natural techniques that
restore an ecosystem’s ability to approach a pre-disturbance condition are distinct
from treatment technologies or structures that are inserted into the system to be
acquired sustainable equilibrium. Natural restoration techniques use materials
indigenous to the ecosystem and are incorporated into the dynamics of an coastal
ecosystem in an attempt to create conditions in which coastal ecosystem processes
can withstand and diminish the impact of stressors on the coastal environment. In
Chilika wetland ecosystem, the salinity is restored due to open cut of the sand bar
and entered much volume of sea water and increased the salinity concentration in
the wetland. Subsequently, the fish population increased in the Chilika wetland ecosystem. Similarly, Vembanad wetland ecosystem, also restored the fisheries population by operating the gates of the weirs in the region.

14.1 Introduction
Water has many wonderful, novel and unique properties. Due to this characteristic
of water gets polluted by various sources like point and non point from industrial
and domestic waste water. Present day scenario, the water ecosystem is damaged,
contaminated, polluted even not for designated best use in the world. India also
witnessing the development of industries, over population, releases industrial effluents and domestic sewage in to the coastal water body. The water is over exploited
