Water dam model project for the school science exhibition using the best out of waste


In this topic, we are going to show you how to make a water dam model for your science project or exhibitions.

Water Dam Explanation

Water dam is used as barriers to stop the flow of water. Dams create water reservoirs which provide water for activities like human consumption, irrigation, aquaculture, navigability and finally for industrial purpose usage.

Dams help in an increased amount of water which helps in generating hydroelectric power, to reduce excess floodwater created by heavy rains, heavy snowmelt or large storms or to increase water depth in the river to improve navigation for ships to travel more easily.

Dams help in forming lakes which can be used for recreational activities such as swimming, boating, and fishing.

Auxiliary works help dam to function properly includes movable gates, valves, and spillways that control surplus water release to downstream from the dam.

It contains an intake structure to deliver water to canals, pipelines, power station, and tunnels.

Dams can be designed to conserve water resources on a regional basis.

Prepare for Science Fair Questions & Answers – Water Dam Model

  1. What is the dam?
    The dam is a structure built across a stream or river mainly to retain water. The water reservoir is used for generating electricity, fishing and to supply water to the irrigation system.
  2. What are the different types of dams?
    There are three types of dams namely gravity, arch and buttress. Mass weight of concrete and friction in concrete gravity dams resist reservoir water pressure.
  3. Why are dam walls curved?
    Arc dam is designed so that the force of water against it and presses against the arch helps in compressing and strengthening the structure as it pushes into its foundation.
  4. What is the world’s largest dam?
    The largest dam located in China is called “Three Gorges Dam”.
  5. Which is the first arch dam in India?
    Idukki Dam located in Kerala, India is 168.91 m (554 feet) tall arch. †


Water dams help human beings a lot by storing a large reservoir of water which can be used for various purposes. Example: Irrigation, Industrial usage, and generation of hydroelectric power.
