DOWNLOAD EBOOK →Excerpt from Hydraulic Design of the Box Inlet Drop Spillway This paper contains sufficient information to permit the complete hydraulic design of a box inlet drop Spillway and explains briefly the various factors that influence the de sign. Its four major sections deal with the free flow capacity, the outlet design, the sub merged flow capacity, and the utilization of the preceding information in the design of box inlet drop spillways. The box inlet drop Spillway may be described as a rectangular box open at the top and at the downstream end. The Spillway is shown in figure 1. Storm runoff is directed to the box by dikes and headwalls, enters over the upstream end and two sides, and leaves through the Open downstream end. An outlet structure is attached to the down stream end of the box. The long crest of the box inlet permits large flows to pass over it with relatively low heads. Yet the width of the Spillway need be no greater than that of the exit channel. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

DOWNLOAD EBOOK →Excerpt from Design of an Outlet for Box Inlet Drop Spillway The outlet as designed in the past could more properly be called an apron, with the floor set at the grade of the downstream channel. The water leaves the apron at a high velocity, causing a horizontal whirling action of the water on each side of the channel. These whirls result in severe scour of the dam fill and the stream bed at the end of the apron. Outlets of this type have failed; two typical failures are shown in figure 1.
