IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

3-D Flow Characteristic of Thermally Stratified Water in Reservoirs
Author : Bingdong Li
Water temperature in vertical will change seasonally for heat accumulation in a reservoir. Because of temperature difference between surface water and bottom water, buoyancy driving water flow will play a key role and will not be ignored. In many cases water temperature distribution will be changed by 3-D flow patterns around intakes of a power station. And so temperature structure of thermally stratified water nearby may be destroyed by this changing. To predict flow characteristics of thermally stratified water, a turbulence model of shear stress transport was applied for 3-D numerical simulation on thermally stratified water flow in a physical model reservoir. Velocities from this mathematical model fit well with the observed data. And this model can present unique 3-D characteristics on thermally stratified flow in a reservoir.
