Installation of inflatable dams where previously small concrete dams used to be constructed is among the environmental solutions adhered to in recent years. An inflatable dam is a thick synthetic tube, which is usually installed across a river, and confronts the flow by being filled or emptied with air or water, to an arbitrary height. Inflatable dams may contain a deflector or lack it. As the foundation invert elevation affects the dam’s performance, it may be placed at different elevations relative to the streambed. A stilling basin is formed when the invert is lower than the streambed; otherwise, the invert basin, maybe flush with the streambed. Hydraulic parameters such as the flow rate, the depth of water on the upstream and the downstream of a dam, and the depth before and after hydraulic jump were measured and the flow energy loss over the dam was computed. A decreasing trend in the relative energy loss with an increase in the drop number was observed.
