Abstract:
Temperature of water body is an important parameter which influence various physical, chemical and biological processes and inturn has effect on aquatic life. Large reservoirs and lakes which have negligible through flows during non-monsoon periods exhibit thermal stratification due to water temperature variation over the depth. This thermal structure undergoes seasonal changes. The waste heat disposal from power plants to water bodies also adds to these stratification effects. The temperature stratification data of some reservoirs in India (including some loaded with thermal discharges) has been analysed in the paper in view of importance of water temperature for engineering and environmental process.
