Define a weir and its function in water management.
A weir is like a small dam built across a river or stream. Its main job is to manage and measure the flow of water.
Here’s how it helps with water management:
Measuring Water Flow: It helps you see how much water is flowing by making the water rise over the top.
Controlling Flow: It keeps the water levels steady, which can help prevent flooding or ensure there's enough water where it’s needed.
Diverting Water: You can use it to direct water to irrigation systems or reservoirs.
Preventing Erosion: By controlling how fast the water flows, it helps protect riverbanks from washing away.
So, think of a weir as a handy tool for managing and using water more effectively!
