What is Chute Spillway

Chute spillway also is known as through spillway. A chute spillway consists of an open channel, by which water conveyed from the reservoir to the river or to Nalla bellow the dam, through fairly steep slope.

The chute spillway is the simplest type of a 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.  

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 in a bank of the river separated from the main dam by a high rigid, it is called a saddle weir.
