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.

    Unobstructed Opening Definition in Methane Mitigation Unobstructed Opening: Per the Los Angeles Department of Building and Safety (LADBS) Methane Code, Ordinance Number 175790, an unobstructed opening is a permanent clearance or gap in the walls, floors, or ceiling of a structure, to allow for direct fresh airflow. In methane mitigation plan applications, this does not…

    Aphanitic Definition Aphanitic: In geology, the term aphanitic describes the texture of plutonic or volcanic igneous rocks, with grains that are not visible to the naked eye. In fact, an aphanitic texture is usually the result of faster cooling and solidification of liquid magma.

    Natural Gas Natural Gas: In geology, natural gas means combustible hydrocarbon gas that forms by natural geological or biological processes. To illustrate, natural gas that forms by geological processes is the thermal decomposition of buried organic materials. Whereas natural gas that forms via biological processes entail the microbial decomposition of buried organic material. Natural gas…

    Polychlorinated Biphenyl (PCBs) Polychlorinated Biphenyl (PCBs): Polychlorinated Biphenyl (PCBs) are highly toxic human-engineered chlorinated hydrocarbons that have been used around the world as enhancers to hydraulic oil and electrical insulators. PCBs were applied for maintaining low flammability rates, high boiling points, and stronger chemical stability. As of 1979, PCBs have been banned from use in…
