What is Chute Spillway
The chute spillway is also known as the “through spillway”. A chute spillway consists of an open channel, by which water is conveyed from the reservoir to the river or to Nalla below the dam, through a fairly steep slope.
The chute spillway is the simplest type of spillway which can be easily provided independently and at low costs. It is lighter and adaptable to any type of foundation and hence provided easily on earth and rockfill dams. Â
A chute spillway is sometimes known as a waste weir. If it is constructed in continuation to the dam at one end, it may be called a flank weir. If it is constructed in a natural saddle on a bank of the river separated from the main dam by a high rigid, it is called a saddle weir.
