Concrete Gravity Dam

What is a Concrete Gravity Dam?

A Concrete Gravity Dam is also known as “Gravity Arch Dam,” and is a freshwater-retaining concrete structure that has a wider footing (base) than the top-section. The purpose of a Concrete Gravity Dam is to maintain a low center of gravity, in order to avoid collapsing in the event of an abutment seal failure. In fact, a Gravity Arch Dam that is properly placed atop geologically stable formations is the safest type of dam. The other types of dams are Embankment Dams, Concrete Arch Dams, and Concrete Slab & Buttress Dams. Concrete Gravity Dams also require the most material for construction. Thus, there is usually a large portion of nearby rock fragments in the cement as aggregate.

    Juvenile Water Juvenile Water: In geology, juvenile water is water derived directly from magma, introduced into the Earth’s surface through geological processes such as magmatic and volcanic activity. Since juvenile water is derived from Earth’s center, its characteristics, are associated with higher temperatures and pressures.

    Permeability “Permeability” in engineering geology and geotechnical engineering refers to the property of a soil sample (or porous rock) which relates to transmitting a fluid within. Permeability measures the relative case of flow under unequal pressure. Permeability is calculated using Darcy’s Law.
