The hydrologic design of the drop inlet structure consists of knowing both the peak rate of runoff expected and also the inflow hydrograph.
The latter is needed as temporary storage of water is created in case of these structures.

The drop spillway is a weir structure. Flow passes through the weir opening, drops to an approximately level apron or stilling basin and then passes into the downstream channel. Drop spillway is one of the most commonly used gully control structures. It is mainly used at the gully bed to create a control point.
CHUTES AND DROP SPILLWAYS (ENTRANCES-WEIRS) Weirs (e.g., Fig. 1) are the inlet sections of chutes and drop spillways, which are often required to drop water over steep sections of the landscape where flow velocities would be too erosive for an earth or vegetated channel. The flow through a weir, q, is described by the weir equation: 2 3File Size: KB.
DROP INLET SPILLWAYS General The drop inlet spillway is commonly used for providing flood protection for earth dams which have smaller reservoirs and/or smaller basins. Genera lly, the spillway is designed to pass floods up to a chosen SDF under a specific amount of surcharge above the reservoir FSL.

On developing the spillway crest onto a plane (i.e., unfolding the side- walls into the same plane as the endwall) a rectangular weir having n crest length of (2 B + W) will be obtained for the box.

The data were analyzed to quantify flow depth, energy dissipation, and an estimate of flow resistance in the form of the Darcy friction factor f Results of the analysis were then used to propose a design procedure for estimating the hydraulic characteristics of stepped spillway flow using typical required information.
HYDRAULIC DESIGN OF THE BOX-INLET DROP SPILLWAY By FRED W. BLAISDELL and CHARLES A. DONNELLY, hydraulic engineersj Soil and Water Conservation Research Division^ Agricultural Research Service INTRODUCTION This handbook contains sufficient downstreaminformation.
The straight drop spillway (fig. 5) is simply a vertical wall with a notch in it. In the case of the box inlet (fig. 6), the notch is still a rectangular shape, but the horizontal bottom of the weir is lengthened by placing a "box" on the upstream side of the wall. This effectively increases the.
DROP SPILLWAYS 1. GENERAL Description. The drop spillway is a weir structure. Flow passes through the weir opening, drops to an approximately level apron or stilling basin, and then passes into the downstream channel.
The basic elements of the drop spillway and the nomenclature are shown by drawing ES (page 1,3). The design of the aerator becomes more complex for orifice spillways because of the short length of spillway, large variation in reservoir water level, and wide range of Froude numbers varying.
An unsurpassed treatise on the state-of-the-science in the research and design of spillways and energy dissipators, Hydraulics of Spillways and Energy Dissipators compiles a vast amount of information and advancements from recent conferences and congresses devoted to the subject.

A new shaft spillway composed of an inlet structure that includes inlet swirling-flow-generating piers, an annular weir, a vertical shaft, and an outlet structure is presented.
Major factors influencing the inlet’s discharge coefficient, including the number of piers, pier weir angle, weir head, and pier height are discussed.
