Abstract: The report contains a brief review of procedures to be used for assessment of the consequences of dam failure and the associated risks is presented for development of the design flood. This is followed by a discussion of innovative spillway designs and the state of the art in dam overtopping protection alternatives. For spillway design, this report especially focuses on the use of labyrinth spillways and fuseplug embankments. For overtopping protection systems, the report assesses roller-compacted concrete and precast concrete blocks for smaller dams and cast-in-place reinforced concrete slabs for larger dams. Nonstructural alternatives such as revised reservoir operating requirements and downstream early warning systems are also addressed.
