GENERAL

River water temperature is arguably one the most significant parameter that influences physical, chemical and biological properties of stream water.  It plays a crucial role in water quality as well as in the overall health of aquatic ecosystems (e.g., distribution and growth rate of aquatic organisms).  Therefore, a good knowledge of the thermal regime of rivers is essential. 

Research focus:

• Understanding and quantifying river thermal regimes
• Better quantification of river heat fluxes (surface and streambed fluxes)
• Development of water temperature models (deterministic / stochastic)
• Study air-water temperature relationships
• Study impact of river thermal regime on water quality and fish habitat
• Study of water temperature dynamics below reservoir
