Dams are that act as barriers constructed across waterway to control the flow or raise the level of waterThey are a non polluting source of producing electricity.It also promotes agriculture and fishing.
dams that r used for more than 1 purpose
Dams are called multi-purpose projects because they serve several functions beyond just water storage. They generate hydroelectric power, provide irrigation for agriculture, facilitate flood control, and offer recreational opportunities. Additionally, they can improve water supply for domestic and industrial use, contributing to overall economic development and environmental management in the region.
The purpose of the dams that are found in the state of PA are to prevent water from entering another water source or landform. Dams are often manmade, but can be constructed by animals like beavers.

Multipurpose projects are engineering works that serve multiple functions such as hydroelectric power generation, irrigation, flood control, and water supply. These projects aim to maximize the benefits of water resources for various uses while minimizing negative impacts on the environment. Examples include dams and reservoirs that provide a combination of services to meet the needs of society.
One of the merits of multipurpose project of dams include source of energy and control over flooding. Demerits, on the other hand, include cost and potential outbreak.
As of recent estimates, there are approximately 90,000 dams in the United States, with around 15% considered inactive or non-operational. These inactive dams may no longer serve their original purpose, such as flood control or water supply. However, the exact number of inactive dams can vary, as conditions may change over time and local assessments are continuously updated.
To control the river and flooding and produce electricity.
AnswerAt least 15.
The Idukki Hydroelectric Project is the biggest hydrolectric Project in Kerala (India). It comprises of three dams at Idukki, Cheruthony and Kulamavu and related systems.
The Chambal Project primarily includes the Gandhi Sagar Dam, the Rana Pratap Sagar Dam, and the Jawahar Sagar Dam. These dams are located in the Chambal River basin and are designed for irrigation, water supply, and hydroelectric power generation. The project plays a crucial role in water management and agricultural development in the region.
Dams serve the common purpose of retaining water.Other structures like floodgates or levees are used to manage or water flow into specific land regions.
