Dams

Answer: Dams are constructed to hold water, meet agricultural needs, and lessen the effects of flood-related calamities. In addition to helping to solve the energy crisis, dams are important for producing hydropower, a clean type of energy.

Answer: There are many advantages of dams from which some of the important are given below;

1. Water storage

One could argue that one of the main purposes of dams and reservoirs is to store water. Reservoir water helps to compensate for water shortages during dry seasons. Additionally, it guarantees a steady supply of water for domestic, commercial, and agricultural use.

2. Irrigation

The function that dams serve in irrigation is one of its most important advantages. Dams have made it much easier for farmers to deal with the issue of watering crops, which has increased crop productivity.

3. Production of Electricity

In many Indian districts, hydropower has become an efficient solution to the country’s ongoing energy crisis. Additionally, hydropower is a clean source of energy and does not produce any pollutants. Some of India’s top hydropower facilities include the Srisailam, Tehri, and Sardar Sarovar dams.

Answer: While dams have many positive effects on civilization, they also are the major threats to river ecosystem, fish habitat, wildlife and ultimately people.

1. Fish are restricted in their capacity to migrate, find spawning habitat, find food, and avoid predators because of dams.

While stagnant reservoir pools can greatly lengthen the migration of fish and disorient aquatic organisms, who need continuous flows to guide them.

2. Water bodies are physically impeded by dams and reservoirs because they fragment them and have an impact on their seasonal flow.

3. One persistent problem that the authorities frequently ignore is the land flooding and widespread population relocation caused by the construction of big dams.

Answer: A substantial man-made dam is an embankment dam. It is often made by placing and compacting a complicated semi-plastic mound made of different soil, clay, sand or rock compositions. It features a solid, impermeable core and a natural waterproof covering that is semi-permeable.
