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.

Numerical modelling of 3d baroclinic flow and thermal discharge in coastal waters
Author : J. Yao, J.F. Tao and C.K. Zhang
Based on the horizontal orthogonal curvilinear coordinate and the vertical sigma coordinate, a numerical model of 3D baroclinic flow and thermal discharge, coupled with turbulence closure model, is developed to simulate the movement of thermal flow from heat or nuclear power station. In order to investigate the effect of salinity and stratified ambient water on thermal discharge, a numerical test of 4 salinity difference between initial thermal discharge and ambient water and a numerical test of stratified ambient water are performed, respectively compared with numerical test of homogeneous density water. The comparison results show that, with the effect of 4 salinity difference, heat distribution is on every vertical layer due to the effect of gravity of salinity water; in the stratified ambient water, the structure of circulation and surface temperature distribution are changed. The conclusion can be drawn that salinity difference and stratified ambient water have some influence on the thermal transfer.
