| Abstract | ||||
| The culvert is a structure that allows water to flow under a road, railway, or corridor, and it is one of the important water facilities due to its use in many practical applications. These facilities are used in crossing small waterways under roads, as well as in crossing seasonal waterways that are used to collect rainwater to resist torrential rains in rainy valleys. and their proper design is critical to ensure a safe and reliable transportation network, but there are some problems facing the structure, such as blockage, soil collapse, and closure due to the maintenance period and head losses. The performance of the culverts must be improved, the head losses must be reduced, and the best of hydraulic structure must be chosen. Where, the selection of number of pipes with area equivalent to area of one pipe and different discharges from 1.59 lit./sec to 16.88 lit/sec and various submergence ratio (1.5, 2, 2.4). the effect of the existence pipe (or pipes) culvert on the flow characteristic such as, water depth (upstream and downstream), submerged ratio, flow intensity or (Pipe Froude number) and energy loss were investigated and analyzed using a series of figures to identity the best case from hydraulic point of view. | ||||
