ABSTRACT:
A spillway for use in a sloped embankment which defines a top and a toe. The spillway is adapted to dissipate the kinetic energy of water flowing downwardly from the top of the embankment to the toe thereof in a primary flow direction. The spillway comprises a plurality of building blocks arranged in rows which are stacked upon each other in a shingle-like overlap such that the building blocks of each row are offset relative to the building blocks of each adjacent row and a series of steps are defined thereby. The building blocks are sized and configured such that water cascading down the steps defined thereby is caused to flow in three dimensions so as to impart velocity components to the falling water that act at generally right angles relative to the primary flow direction and generate turbulence which dissipates the kinetic energy of the water.
