This paper deals with a numerical model to simulate flow through a box culvert, which represents flow during flash floods under highways in Oman. We firstly show the typical flow patterns with the transition from free surface flows to pressurized flows and overflows over a culvert, based on hydraulic experiments. Then, a numerical model applicable to the full/partial full pressurized flows is tested to simulate the typical flow patterns under the conditions of experiments.It is pointed out that although the numerical model used here can simulate the simple flow patterns to some extents, the model should be improved further to get better results.
