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.

To get better understanding of its vertical thermal structure and temperature variation throughout a year, observation of vertical temperature distribution in front of the dam was carried out in 2014. These data have confirmed the existence of stable vertical thermal stratification in summer and autumn. To get better view of temperature variation after impoundment, a two-dimensional longitudinal-vertical hydrodynamic and water quality model (CE-QUAL-W2) was employed to simulate water level and vertical thermal structure. The data of 2013 was used to calibrate the model. And then, a working condition of regular operation year was set. The simulation result briefly depicts the thermal structure and its variation throughout a year. Beside what have been done in this research, a further study associated with the relationship between temperature structure and discharge distribution should be made to guide the management of Xiluodu Reservoir.
