What was built along the streams to create reservoirs of varying sizes...
The correct answer is b) Embankments. Embankments are structures that are built along streams, rivers, or other bodies of water to create reservoirs of varying sizes. Embankments are typically made of earth or other materials and are designed to hold back water and create a reservoir or pond. Embankments may be built for a variety of purposes, including irrigation, flood control, and hydroelectric power generation.
A) Culverts are structures that allow water to flow underneath a road, railway, or other obstacle.
C) Riverbanks are the sides of a river or stream.
D) Dikes are embankments or barriers built to protect low-lying areas from flooding.

What was built along the streams to create reservoirs of varying sizes...
Embankments were built along the streams to create reservoirs of varying sizes. Embankments are artificial banks or walls made of earth, stone, concrete or other materials that are constructed along a river or stream to control its flow or hold water back. They are often used to create reservoirs or artificial lakes for irrigation, water supply, flood control, or hydroelectric power generation.
Benefits of Embankments:
- Embankments are an effective way to store water in areas where natural lakes or ponds are not available.
- They can help regulate the flow of water and prevent floods by holding back excess water during heavy rains or snowmelt.
- Embankments can also be used to create hydroelectric power by trapping water in a reservoir and releasing it through a turbine to generate electricity.
- They can provide a reliable supply of water for irrigation and other agricultural activities.
Construction of Embankments:
- The construction of an embankment begins with a survey of the land to determine the best location and design of the embankment.
- The embankment is then constructed by excavating the ground and placing the soil or other materials in layers to form the wall.
- The wall is then compacted and reinforced with materials such as gravel, rocks, or concrete to make it stable and durable.
- Once the embankment is complete, it is usually covered with vegetation to prevent erosion and improve its aesthetic value.
In conclusion, embankments are an important engineering solution for storing water, regulating its flow, and providing other benefits such as flood control and hydroelectric power generation. They are built along streams and rivers using various materials and construction techniques to create reservoirs of varying sizes.
