Adaptation of the Radial Flow Energy Dissipator for Use with Circular or Box Culverts

摘要

An investigation was undertaken to explore methods of adapting the radial flow energy dissipator previously developed for a box culvert for use with a circular culvert. The basic criteria used in investigation of the effectiveness of various geometric arrangements as energy dissipator were the stability of hydraulic jump, the efficiency of the spreading action, and the degree of velocity reduction in the jump. The more complex geometric forms are compared to the simple curved drop section. From the evaluated results, it appears that relative simplicity of construction is a strong argument in favor of the arrangements with the simple curved drop and straight horizontal transverse elements.
