| dc.description.abstract | The object of the study was to develop design criteria for three classes (A, B and C) of rigid boundary energy dissipating structures. The Class A basin has a smooth floor and flaring vertical walls; the Class B basin is a rectangular basin with smooth floor and vertical walls; the Class C basin is a rectangular basin with smooth vertical walls and an artificially roughened floor. Design aids developed during this study include: dimensionless coefficients for the energy and momentum equations which correct for nonhydrostatic pressure distribution and nonuniform velocity distribution at the outfall sections of circular and rectangular conduits; dimensionless water surface contours and velocity vectors for freely expanding jets supported on the bottom, downstream of circular and rectangular abrupt expansions; drag coefficients for roughness elements of known size and spacing; and other minor criteria. Numerous existing criteria, including Blaisdell's criterion for wall flare, Ippen's relationships for predicting the angle of oblique standing waves and Albertson, et al.'s relationships for determining the properties of the flow field downstream of culvert outlets operating under high tailwater conditions were verified. Design procedures based on continuity of flow and the balance of impulse and momentum from station to station are presented for the three classes of basins. Alternate refined procedures utilizing backwater computations are outlined for Class A and B basins. Numerous example problems are solved in detail in Chapter VII. It is suggested that the energy basin be constructed within the roadway prism as an integral portion of the culvert barrel. Discussions concerning the necessity of tailwater control and of other important factors which should be considered accompany the design computations. | |
