Planned Overtopping of Embankments Using Roller Compacted Concreteby Gary N. Reeves, Freese & Nichols Inc, Fort, Worth, TX, USA,
Abstract: Three recent projects are discussed where the economy and versatility of roller compacted concrete (RCC) were utilized to allow flood water overtopping of small to medium size embankment dams. Two of the projects were new structures designed and constructed with unusual site and operation restrictions, which made conventional spillway control of flood flows impractical. The other project was renovation of a dam more than forty years old with inadequate spillway capacity by today's standards. In all of the three cases, the economy of the design was a major factor. A discussion of the practical application of RCC in planned overtopping designs is also included.
