Research on Vertical Distribution of Water Temperature in Different Regulation Reservoirs

Abstract

The vertical distribution of the reservoir water temperature depends on the scale of the reservoir, regulation manners, as well as the hydrological and geological conditions near reservoir areas. Based on water temperature observation from three different regulation reservoirs, this paper analyses the vertical distribution of these reservoirs water temperature. The preliminary conclusions are: for multi-annual regulation reservoirs, the upper zones usually have stable temperature stratification structures, while the lower zones have constant low temperature; for annual regulation reservoirs, water temperature distribution changes with depth; for the daily regulation reservoirs with low water depths present mixed vertical distributions of water temperature.
