The small scale modeling of aeolian sand deposition at porous fences is indeed a complex area of study. Wind tunnel modeling of control structures, such as fences, has sufficient advantages over field testing to warrant some discussion of the realism of such experiments. Control of experimental factors such as wind direction and duration is a primary advantage. It is also advantageous to be able to perform many experiments over a short period of time and even to alter particle properties by using different sands. In this paper, general curves and equations are developed for the wind tunnel and Aswan, Abo- Simble, Toshka and Kwait desert areas as cases study. By using these curves the accumulated sand height may be predicted at a given time or for a given fence height
