GRAVITY DAM Meaning and
Definition
-
A gravity dam, in hydraulic engineering terminology, refers to a type of structure that is built using concrete or masonry materials to withstand the force of water pressure, commonly found in rivers or reservoirs. Its primary purpose is to restrain the flow of water and create a barrier for hydraulic projects, such as irrigation, hydroelectric power generation, or water supply systems.
Characterized by its sheer weight and mass, a gravity dam is constructed in a manner that allows it to resist and counteract the hydrostatic pressure resulting from the water it holds back. This type of dam typically slopes upstream against the flowing water and relies on its self-weight and interlocking design to maintain stability.
The immense gravity of the dam counters the forces exerted by the water, preventing it from breaching the structure. The weightier the dam, the greater its resistance, which makes it advantageous for situations where height is a primary concern, or when the foundation conditions are not suitable for other types of dams.
Gravity dams are commonly built with a trapezoidal cross-section, wider at the base and tapering towards the top, allowing for a stable pyramid-like form. This style of construction distributes the water pressure throughout the structure, alleviating the risk of localized excessive stress. Moreover, its solidity and durability make it more resistant to floods and erosions caused by water flow.
Overall, gravity dams are essential components of water management systems, offering reliable and long-lasting structures for various hydraulic projects.

Etymology of GRAVITY DAM
The word "gravity dam" derives its etymology from the Latin word "gravitas", which means "heaviness" or "weight". In the context of dams, a gravity dam refers to a type of dam structure that relies on its own weight and mass to resist the horizontal thrust of water against it. The construction materials used in these dams, such as concrete or masonry, are intended to hold up against the force of gravity and the pressure of the water. Thus, the name "gravity dam" emphasizes the significant role of gravity in the design and stability of this type of dam.
