A Hydrological Study of Ashtamudi Lake, Kerala, India with Special Reference to its Ecological Difference

The life in aquatic system is directly or indirectly depends on the water quality. The alteration of physicochemical parameters of water affects the abundance of biota and their diversity. The Ashtamudi Lake shows differences in ecological conditions and hydrological factors. Hence an attempt was made to evaluate and confirm how far the hydrological parameters influence the different sites of the lake. Different hydrological parameters from five ecologically different areas are studied for three years. Ecological difference have an influence in the hydrological parameters are established and this was discussed with similar works in other lakes.
