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.

An Analytical Model for Simulation of Air-Water Flow Roghayeh Ahmadpour1, Hamed Sarkardeh2, Seyed Amin Salamatian3 1 M.Sc. Student, Department of Civil Engineering, Al-e-Taha Institute of Higher Education, Tehran, Iran, r_ahmadpour1990@yahoo.com 2 Assistant Professor, Department of Civil Engineering, Faculty of Engineering, Hakim Sabzevari University, Sabzevar, Iran, sarkardeh@hsu.ac.ir 3 Assistant Professor, Department of Civil Engineering, Shahab Danesh Institute of Higher Education, Qom, Iran, amin.salamatian@gmail.com In the present analytical study a two dimensional analytical model was developed for calculating air concentration in air- water flows. To do so, the related partial differential equations in the whole flow domain were solved. The solution was then applied in a free surface flow with air content. The results of analytical model was verified and compared with a numerical and another analytical model .The concluded results showed close agreement with previous data. This comparison showed also that the decrease in air concentration near the channel bed in an aerated flow could be well predicted by the model.
