Arthur P. Morgan came to Dayton after the 1913 flood to design a flood control system to protect the entire Miami Valley. One element of this system was a dry dam—a dam that held water only during a flood and released the water at a rate that the downstream riverbed could carry. The problem was that the speed of the water through the dam made it powerful and destructive. To solve that problem, Morgan went with Col. Edward Deeds to Deeds’ farm in Moraine, where they built models in his swimming pool. They developed the hydraulic jump, which sends water through a series of baffles and steps, and then finally into a low wall that forces the water back onto itself, dissipating its own energy. This process of turning water onto itself is the hydraulic jump. From there, the water flows downstream calmly. This technology is still used in hydrological engineering throughout the world. RiverScape demonstrates the hydraulic jump in the fountain that falls down the levee from Festival Plaza to the harbor.
