The Relation of Water Temperature and Heat Balance on Water Surface in Summer at Ara-River

Abstract

Field observations were conducted at Ara-river in 1993 summer to evaluate the effect of heat balance on water temperature. The observation in the river course consists of measurements on long-and short-wave radiations, heat and vapor fluxes on water surface and measurements on vertical distribution of water temperature, saline concentration and transmissivity of solar radiation through the water body. The development of thermocline in the water body associated with net radiation was observed.
