CONCLUSION |
Land-use analyses with catchment hydrologic parameters indicate that, the catchments dominated with evergreen-semi evergreen type of forests have higher stream density and most of the streams are perennial compared to catchments dominated by anthropogenic influences.
The variation in dissolved oxygen and free carbon dioxide is due to stagnant or flowing nature of the water body. The variation in phosphates and coliform is due to the anthropogenic activities in the catchment. The catchment area is mainly covered with forest and agricultural lands. The streams drain from agricultural area showed high phosphates value, reflecting that land-use linkage with the stream water quality. The water quality of the river is free of contaminants and serves as a suitable habitat for aquatic plants and animals
The Ministry of Science and Technology, Government of India provided the financial assistance to carry out field investigations. We thank Lakshminarayana, and Vishnu for assistance during the field investigations. We are grateful to Gururaja, K. V., Sreekantha, Sameer Ali and Shruthi, B.V. for useful suggestions during discussions.
