#71 Small Weir

Pictured here is a small weir. A weir is simply a wall or some sort of barrier placed within an open channel which restricts the movement of water as it flows downstream. Weirs are used to change the flow characteristics in a stream or river and manage the flow rate within the channel. In this way, engineers can use devices such as the weir to prevent flooding and sustain the safety of the public.
