Spillways on River Levees [PDF]
, 2021 Levees are built on many rivers and mountain torrents to protect populations against floods. During medium floods, a well-constructed levee offers sufficient protection without requiring additional hydraulic structures. But this same levee represents a source of danger during high floods, since there is a risk of overtopping.

Performance Assessment of Shockwaves of Chute Spillways in Large Dams
Shock and Vibration, 2021 Spillways are the most important structures of large dams that are responsible for releasing the excessive flood discharge from the reservoir. Although many studies have been performed to determine the flow characteristics over these structures, however,

Location of inception point of alternating steps stepped spillways
Sulaimani Journal for Engineering Sciences, 2023 This study explored the effects of flat-stepped spillways having alternating steps on the inception point location. Two wooden stepped spillways with a longitudinal slope of 26.6° were constructed in a rectangular flume and tested at various discharges ...
