What Is the Purpose of Masonry Dam
The purpose of a masonry dam is to serve as a structure to contain water.
These dams are made of stone and brick and are sometimes joined with mortar.
They can be either gravity or arch-gravity dams.
The Nagarjunasagar Dam in India, located in Andhra Pradesh and Telangana, is the largest masonry dam in the world.
Masonry dams are designed to regulate and control water flow, store water, and generate hydroelectric power, providing vital resources for irrigation, drinking water, and energy production.
Did You Know?
1. The tallest masonry dam in the world is the Nurek Dam, located in Tajikistan. It stands at a staggering height of 300 meters (984 feet), equivalent to a 100-story building.
2. The purpose of a masonry dam is not only to store water but also to generate hydropower. By harnessing the potential energy of water, masonry dams can generate electricity for homes, industries, and entire cities.
3. Many masonry dams have a lifespan of around 100 years. However, with continuous maintenance and upgrades, the Hoover Dam in the United States remains fully functional even after more than 85 years since its completion in 1936.
4. The construction of a masonry dam often requires precise engineering calculations. The gravity holding capacity of the dam needs to surpass the hydrostatic pressure exerted by the water, ensuring its stability and preventing any potential failure or collapse.
5. Some masonry dams, such as the Grand Coulee Dam in the United States, have incorporated intricate artwork and bas-reliefs in their architectural design, depicting scenes of local wildlife, historical events, or cultural heritage to beautify the structure and celebrate the surrounding natural environment.
Construction Materials Used For Masonry Dams
Masonry dams, as the name suggests, are primarily constructed using stone and brick. These natural materials have been used for centuries due to their durability and resistance to water erosion. The stones are carefully placed and sometimes joined together with mortar to ensure a strong and secure structure.
The use of stone and brick in masonry dams can be traced back to ancient civilizations such as the Romans and Egyptians, who harnessed the power of water for irrigation and to control floods. Over time, technological advancements have allowed for improvements in the design and construction of masonry dams, but the basic principle of using stone and brick remains unchanged.
The choice of construction materials for masonry dams is crucial as they need to withstand immense pressure exerted by the water they contain. The stones used should be strong and capable of withstanding the hydrostatic forces generated by the water. The mortar is also an essential element as it helps bond the stones together, creating a cohesive structure that can withstand the test of time.
Function Of Masonry Dams: Water Containment
The primary purpose of masonry dams is to contain water. These structures are built to impound rivers, streams, and other bodies of water, allowing for water storage and control. This water can then be used for various purposes such as:
- Irrigation
- Drinking water supply
- Hydroelectric power generation
- Recreational activities such as boating and fishing.
Masonry dams play a vital role in water conservation by regulating the flow of water. They help control flooding by storing excess water during periods of heavy rainfall and gradually releasing it when the river flow subsides. Additionally, they aid in maintaining a steady water supply during dry seasons by storing it for later use.
Furthermore, masonry dams contribute to the sustainability of ecosystems by creating reservoirs that provide habitats for various species of plants and animals. These reservoirs can also support biodiversity by serving as recreational areas and attracting wildlife.

Types Of Masonry Dams: Gravity And Arch-Gravity
Masonry dams can be classified into two main types: gravity dams and arch-gravity dams.
A gravity dam is a massive structure that relies on its own weight to resist the horizontal pressure of the impounded water. The weight of the dam, combined with the force of gravity, allows it to remain stable. This type of dam is usually wide at the base and gradually tapers towards the top. The width helps distribute the force of the water evenly and prevents the dam from overturning.
On the other hand, arch-gravity dams combine the principle of the gravity dam with the arch structure. These dams have an arched shape at the crest, which helps in distributing the forces exerted by the water. The arch shape provides additional stability, making arch-gravity dams suitable for areas with high water pressure. The combination of gravity and arch design allows these dams to withstand greater forces compared to gravity dams alone.
The World’s Largest Masonry Dam: Nagarjunasagar Dam
The Nagarjunasagar Dam, located in India, holds the title for being the largest masonry dam in the world. This magnificent structure spans the Krishna River in the states of Andhra Pradesh and Telangana. Built between 1955 and 1967, the Nagarjunasagar Dam stands as a testament to engineering marvels and the human ability to harness the power of nature for the greater good.
With a length of approximately 1.6 kilometers and a height of 124 meters, the Nagarjunasagar Dam is a monumental feat of construction. It serves multiple purposes, including irrigation, power generation, and drinking water supply to nearby cities and towns. The dam’s capacity to store water is around 11,472 million cubic meters, making it a crucial resource in water management.
The Nagarjunasagar Dam has not only transformed the region’s agricultural landscape but has also become a significant tourist attraction. Visitors are captivated by the sheer magnitude of the dam and the picturesque surroundings it offers. Its presence stands as a reminder of humanity’s ability to create monumental structures to meet society’s continuous need for water management and conservation.
Location Of Nagarjunasagar Dam: Andhra Pradesh And Telangana, India
The Nagarjunasagar Dam is a prominent dam located in the southern part of India, spanning the states of Andhra Pradesh and Telangana. It is situated on the Krishna River, which is one of the longest rivers in India. The Krishna River serves as a vital water source for irrigation and drinking water supply, making the Nagarjunasagar Dam a critical component of water management in the region.
