Types of dams in tamilnadu

 


Tamil Nadu has various types of dams, including major ones like Mettur and Bhavani Sagar, with types ranging from earthen and gravity masonry to gravity & masonry and earthen/gravity & masonry. Major dams serve purposes like irrigation, hydropower, and drinking water, and include famous examples like the Mettur Dam, Aliyar Reservoir, and Vaigai Dam. 

Types of dams by material and design

  • Earthen: Constructed from earth and soil.
  • Gravity and Masonry: Built with concrete or stone, relying on their weight to hold back water.
  • Earthen/Gravity & Masonry: Dams that are a combination of both earthen and gravity/masonry types. 
Examples of major dams in Tamil Nadu
  • Aliyar Reservoir: An earthen/gravity & masonry dam located on the Aliyar River in Coimbatore district.
  • Amaravathi Dam: An earthen/gravity & masonry dam built across the Amaravathi River, a tributary of the Kaveri.
  • Bhavanisagar Dam: A major dam constructed across the Bhavani River in Erode district.
  • Krishnagiri Dam: A dam on the Thenpennai river.
  • Mettur Dam: A major hydroelectric station and tourist spot on the Cauvery River in Salem district.
  • Sathanur Dam: Located across the Thenpennai river.
  • Vaigai Dam: A dam on the Vaigai River.
  • Chittar Dams: Two earthen dams, Chittar I and Chittar II, are located in Kanniyakumari.
  • Emerald Dam: A gravity and masonry dam used for hydroelectric power in the Nilgiris district.

NOTCHES AND WEIRs

Image
   NOTCH ,WEIR AND ITS TYPES Notch A  notch  may be defined as an obstruction over which the flow of liquid occurs   In case of measuring tank or reservoir, the opening is provided at the side of the tank such that the liquid surface in the tank is below the top edge of the opening. Weir A  weir  is a notch on a large scale used for measuring the flow of a river, canal etc. It is a concrete or masonry structure of substantial breadth built across the river in the direction of flow. This allows the excess water to flow over its entire length to the downstream side. Thus a weir is similar to a small dam constructed across the river, with a difference that the excess water flows downstream only through a small portion called  spillway  and in case of weir, the excess water flows over its entire length. Nappe and crest The sheet of water flowing through a notch or over a weir is known as  nappe  or  vein . The bott...

THE BASICS OF REBAR: A COMPREHENSIVE GUIDE FOR BEGINNERS

 THE BASICS OF REBAR: A COMPREHENSIVE GUIDE FOR BEGINNERS The Basics of Rebar If you have ever wondered what gives strength and stability to the concrete structures that we see around us, the answer is (most commonly) rebar. Rebar, short for reinforcing bar, is the steel rods that are embedded in concrete that provide tensile strength to what is actually and prevent cracking. Rebar comes in different shapes and sizes, but the most common type is deformed steel rebar, which has ridges or indentations along its surface to create a better bond with the concrete. Deformed steel rebar has been used in the construction industry for over a century, and it has revolutionised the way we build. With rebar, and using elements such as beams,  beam ties , rebar mesh, and reinforced walls, we can create taller, stronger, and more durable structures that can withstand natural disasters, environmental changes, and human activities. Some of the most iconic buildings in the world, such as...
