Definition And Construction Materials Of Masonry Dams
Masonry dams are remarkable structures constructed using stone, brick, and mortar. These materials are meticulously chosen and combined to produce a robust and enduring dam capable of withstanding the immense pressure exerted by the water it holds back. The use of masonry in dam construction dates back to ancient times when civilizations recognized the necessity of managing water flow for purposes such as irrigation and flood prevention.
The construction process of a masonry dam involves precisely laying stones or bricks in a specific pattern, tightly interlocking them, and bonding them with mortar, which acts as a glue-like substance. This technique significantly enhances the dam’s overall strength and stability, enabling it to effectively resist the forces imposed by the water. Moreover, incorporating spillways or outlets ensures the safe discharge of excess water, thereby averting potential damage to the dam.

Types Of Masonry Dams: Gravity And Arch-Gravity
There are two main types of masonry dams: gravity dams and arch-gravity dams.
Gravity dams rely on their own weight to resist the horizontal forces exerted by the water. The immense weight of the dam provides stability and prevents it from tipping over. These dams are often constructed with a trapezoidal cross-section, with the widest base located at the bottom and tapering as it reaches the top.
On the other hand, arch-gravity dams are uniquely engineered structures that combine the features of both arch dams and gravity dams. The arch shape provides additional structural strength by transferring the weight of the water to its abutments. This design effectively reduces the pressure on the dam, allowing for a more slender profile. The arch-gravity dams’ combination of arch and gravity principles is a testament to the ingenuity of engineers in optimizing dam performance.
The World’s Largest Masonry Dam: Nagarjunasagar Dam
Located in the Indian state of Telangana, the Nagarjunasagar Dam stands as the largest masonry dam in the world. Constructed across the Krishna River, it was completed in 1969 and serves several essential purposes, including irrigation, hydroelectric power generation, and flood control. The dam is an architectural marvel, stretching over 1.6 kilometers in length and rising to a height of 124 meters.
Managed by the Andhra Pradesh Irrigation Department, the Nagarjunasagar Dam plays a crucial role in irrigating the arid lands of the region, ensuring the sustenance of agriculture. Additionally, its hydroelectric power station has a capacity of 816 megawatts, contributing significantly to the electricity needs of the surrounding areas. The dam’s construction and its subsequent benefits have been instrumental in the growth and development of Telangana, improving the lives of millions of people.
Historical Background Of Masonry Dam Construction
The history of masonry dam construction dates back many centuries. Ancient civilizations such as the Egyptians, Romans, and Chinese recognized the importance of dam systems in managing water resources. For instance, the Romans built numerous masonry dams to secure their water supply for cities and agriculture. The iconic Pont du Gard in France, constructed in the 1st century AD, represents their remarkable engineering abilities.
Throughout the medieval period, the construction of masonry dams continued to evolve, with advancements in construction techniques and materials. The Renaissance period saw a renewed interest in studying ancient Roman architecture, which influenced the construction of masonry dams during this time. With the advent of modern engineering practices, these dams have become even more efficient and resilient.

What are the materials used in masonry dam?
The construction of masonry dams relies on the use of various materials to ensure their stability and durability. Inorganic cementitious materials, such as cement and mortar, play a crucial role in the formation of the masonry. These materials provide strength and cohesion to the structure, enabling the stones to be securely joined together. Additionally, the substrate and repair materials used in masonry dams need to be carefully selected to match perfectly, as this ensures that the dam can withstand the stresses resulting from volume changes and load without experiencing distress and deterioration. By employing the right materials, masonry dams can achieve long-lasting performance and effectively serve their purpose in water management.
What is masonry gravity dam?
A masonry gravity dam is a type of dam that is built using blocks or bricks of stone or concrete. It is specifically designed to withhold the force of water by relying on the weight of the material itself and its ability to resist the pressure exerted by the water. This design creates a stable structure that can effectively withstand the horizontal force of the water pushing against it. By utilizing the inherent strength of the materials and the principle of gravity, masonry gravity dams are able to provide reliable water storage and flood control solutions in various locations around the world.
