RÉSUMÉ

Most of the porous media in nature as well as in engineering projects are open to air and approximately all of the flows in these media have an unconfined nature. Therefore study about unconfined flow through open coarse porous media has been widely used in different branches of engineering and sciences. In this study, by introducing a special network which is called "CPFN" (coupled pressurized−free surface network), the unconfined flow through open porous media is studied. In this kind of modeling, initially the physical properties of the equivalent CPFN network must be determined and then by analyzing this network, the hydraulic parameters of flow through real porous media will be determined. In this research, a new method is introduced to analyze the mentioned network, which is discussed in detail in a separate article, and a simple method for determining the geometric parameters of this equivalent network is proposed here. Validation of these proposed models and the related equations are achieved by triggering and monitoring the flow discharge and water surface profile in seven different experimental models which have been built in the hydraulic laboratory at the Engineering School of Shiraz University. Results show good agreement between the predicted values of the network model and the experimental data obtained in the laboratory.
