Impact of Water Quality on the Changing Environmental Scenario of Sunderbans

Changes in the local hydrology in the estuarine river waters of Sunderbans are the most important contributory factors attributable to the changing scenario of mangrove ecosystems. Changes in river courses impede fresh water flow towards Sunderbans. All these changes as a result of regional and global processes and climatic changes cause the changes in the salinity, pH, dissolved oxygen, temperature and all other changes in the physico-chemical parameters in the brackish waters of the Sunderbans. Mangrove distribution is limited worldwide depending principally on temperature and salinity variations of the estuarine river waters.
