7 Different Types of Spillways – theconstructor.org
In this article, we will discuss in brief all the different types of spillways with pictures. Different types of spillways are as follows: 1. Straight Drop Spillway. A Straight drop spillway consists of low height weir wall having its downstream face roughly or perfectly vertical.

This article throws light upon the eight most common types of spillways. The types are: 1. Free Over-Fall (Straight Drop) Spillway 2. Ogee (Overflow) Spillway 3. Side Channel Spillway 4. Chute (Open Channel or Trough) Spillway 5. Shaft (or Morning Glory) Spillway 6. Siphon Spillway 7. Cascade Spillway 8. Tunnel (Conduit) Spillway. Type # 1.
Open Channel Spillways | Association of State Dam Safety
For dams with pipe conduit principal spillways, an open channel emergency spillway is almost always required as a backup in case the pipe becomes clogged. Open channels are usually located in natural ground adjacent to the dam and can be vegetated, rocklined, or cut in rock.

A rock chute spillway is a structure that allows for the safe flow of surface water in an outlet. This type of spillway helps stabil- ize banks by preventing retrogressive erosion of the bottom of waterways (furrows and ditches) and the formation of erosional
For sediment basins with earthen embankments, the principal spillway is a riser structure. The riser is ideally at the deepest point of the basin, and its height is typically 1 foot below the level of the earthen dam. Most jurisdictions require design engineers to size the riser to handle flow from a specific size of storm.
Spillway - Wikipedia
A spillway is a structure used to provide the controlled release of water downstream from a dam or levee, typically into the riverbed of the dammed river itself. In the United Kingdom, they may be known as overflow channels .
Erosion of rock and soil (earth) are major areas of concern when dealing with earthen embankments, unlined spillways, and other features of a water control or flood risk mitigation project.
Scour of rock is a complex process and can be very problematic for dams when excessive scour threatens dam stability. Removal of individual rock blocks is one of the principal mechanisms by which scour can occur, particularly in unlined spillways and on dam abutments.
Drop Spillways - ASDSO Dam Safety Toolbox
The morning glory spillway (sometimes referred to as a “shaft” spillway) has the potential of small to moderate discharge capacity and is used with conduit and tunnel conveyance features. This type of spillway is applicable to concrete, embankment, and composite dams, and it can be gated or ungated. As hydraulic head on the crest increases ...
