Definitions
- A barrier built across a river or stream to hold back water and create a reservoir. - A structure used to control the flow of water, especially for irrigation or hydroelectric power generation. - A wall or embankment built to prevent flooding or protect land from water damage.
- A low dam built across a river or stream to regulate water flow or divert water into a channel. - A barrier used to trap fish or other aquatic animals for harvesting or research purposes. - A structure used to measure the flow rate of water in a river or stream.
List of Similarities
- 1Both dam and weir are structures built across a river or stream.
- 2Both can be used to control the flow of water.
- 3Both can be used for irrigation or hydroelectric power generation.
- 4Both can be used to prevent flooding or protect land from water damage.
What is the difference?
- 1Size: Dams are typically larger and higher than weirs.
- 2Purpose: Dams are primarily used to create a reservoir, while weirs are used to regulate water flow or trap fish.
- 3Construction: Dams are usually made of concrete or earth, while weirs can be made of wood, stone, or concrete.
- 4Impact: Dams can have a significant impact on the environment and wildlife, while weirs have a smaller impact.
- 5Location: Dams are often located in remote areas, while weirs can be found in urban or rural areas.
Remember this!
Dam and weir are both structures built across a river or stream, but they differ in size, purpose, construction, impact, and location. Dams are larger and primarily used to create a reservoir, while weirs are smaller and used to regulate water flow or trap fish. Dams can have a significant impact on the environment, while weirs have a smaller impact.
