How does a gravity dam function, and in what types of terrains is it most commonly used?
A gravity dam functions by using its own weight to offset the force of the water pressing against it horizontally. These dams, which are often constructed of masonry or concrete, rely on their massive thickness and bulk to stay solid. They function best when there is a narrow, steep valley with a strong base and the structure can safely withstand the water load. Gravity dams are labor- and material-intensive, despite being relatively simple to plan and build. The primary advantage of these materials is their inherent stability, which mitigates the risk of failure due to tipping or sliding. They are therefore ideal for particular kinds of terrain.
