Hydrological studies are very significant for the conservation and management of wetland ecosystem. Any alteration of hydrological characteristics of wetlands affects the abundance and diversity of biota. Thattekkad Bird Sanctuary showed differences in environmental conditions and hydrological parameters. Different hydrological parameters from eight ecologically distinct areas were studied for three years. A significant difference was noticed in two periods of wetland and changes were taking place in the water chemistry of the Thattekkad Bird Sanctuary wetland area. And this area were degraded due to habitat alteration.
