A dam is a barrier that restricts or stops the flow of water, helping to suppress floods and providing irrigation, industrial, and aquaculture uses. Here are seven different types of dams and their respective purposes.
1. Diversion Dam
2. Buttress Dam
3. Embankment Dam
4. Cofferdam
5. Storage Dam
6. Detention Dam
7. Gravity Dam
There are many different kinds of dams, each serving a specific purpose. For example, a cofferdam is ideal for creating a dry work site for construction projects.
Here are some of the various types of dams and their uses:
Like the name says, a diversion dam is used to divert water. They provide pressure to push water into ditches, canals, or other areas used for conveyance. Diversion dams are typically lower in height and have a small water storage area in it’s upstream.
Buttress dams can take many forms, but they all consist of a sloping deck supported by intervals of buttresses. There are three main buttress dams, including: multiple arch type, massive head type, and deck type. Buttress dams usually use less concrete than other dams but are not necessarily cheaper.
An embankment dam is a large, artificial dam that is constructed with natural excavated materials or industrial waste materials, such as compacted plastics, and various compositions of soil, sand, rock, and clay.
A cofferdam is a temporary, portable dam used for a variety of projects including bridge repair, shoreline restoration, pipeline installation, and many other construction projects. A cofferdam is used to close off some or all of a construction area.
These dams are not mean to divert or keep water out, but to keep water in. Storage dams are constructed to store water during the rainy seasons, supply water to the local wildlife, and store water for hydroelectric power generation, and irrigation. Storage dams are the most common types of dams.
Detention dams are specifically constructed for flood control by retarding flow downstream, helping reduce flash floods (to some extent). The water is retained in a reservoir to be later gradually released.
A gravity dam is a massive, man-made concrete dam designed to hold large volumes of water. Because of the heavy concrete used, it is able to resist the horizontal thrust of the water, and gravity essentially holds the dam to the ground. They are used to block rivers in wide valleys and must be built on a strong foundation of bedrock.
There are many different kinds of dams, each serving a specific purpose. For example, a cofferdam is ideal for creating a dry work site for construction projects.
Dams are crucial for various applications, including domestic, industrial, and irrigation uses. They provide water for drinking, bathing, hydroelectric power generation, water storage, flood protection, and more.
