چکیده: Abstract: The dam spillway is a hydraulic structure to divert excess water from the reservoir after it is filled to capacity, which is built at the dam site. During fluvial flooding, all kinds of dam spillways provide the path for excess water to exit to the downstream areas, therefore the spillways play an essential role in controlling the flood capacity and ensuring the safety of the dams. Piano key weir is a type of non-linear spillway like labyrinth weir. In this research, different models of piano key weirs with different slopes were made and were investigated as a direct spillway in the laboratory channel
