Chute spillway of Llyn Brianne dam in Wales. 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. Spillways ensure that water does not damage parts of the structure not ...
Many pathways of water can enter through a dam structure to produce a well-defined nappe. However, engineers classify dams as either overflow dams, where water consistently flows over or is blocked through a gate on top of crest, or non-overflow dams, which channel water through or around the dam with emergency floodgates.
An emergency spillway with fuse plug (bottom) and an auxiliary ogee spillway (top) at New Waddell Dam. A fuse plug is a collapsible dam installed on spillways in dams to increase the dam's capacity. The principle behind the fuse plug is that the majority of water that overflows a dam's spillway can be safely dammed except in high flood conditions.
A week of rain brought as much precipitation as the region normally sees in an entire summer. Then the water came for Jenny Barnes' family business.
When the lake's water levels rose, it began to overflow at the top of the pipe connecting to the river, which spans 8-foot-wide and 200-foot-long, and ran at a rate of 48,400 cubic feet of water ...
The dam is located just over 46 miles (74 km) upstream from the mouth of the Nolichucky, and impounds Davy Crockett Lake, [1] [2] which extends 6 miles (9.7 km) upstream from the dam. [2] [3] The dam is a concrete gravity overflow type dam 94 feet (29 m) high and 482 feet (147 m) long. [2] [3] The dam has an ogee-type spillway with a flashboard ...
Floodwaters that gushed from an overflowing dam in northern Nigeria engulfed a zoo and swept animals including crocodiles and snakes into communities, as the region battles some of the worst ...
The dam's design is unusual [a] in having two totally enclosed bellmouth spillway overflows (locally named the "plugholes") at the side of the wall. These are stone and of 78 ft (24 m) diameter with a drop of 66 ft (20 m). The plugholes regulate water levels in the reservoir by draining away excess water when they overflow.
