Concrete Arch Dam

What is a Concrete Arch Dam?

A Concrete Arch Dam is a curved freshwater-retaining structure that is concave in the hydro-geologically down-gradient direction, and uniformly thick from the base to top. With Concrete Arch Dams, a major part of the water load value gets distributed to the abutments of the dam. Thus, Concrete Arch Dams require adequate foundation materials that can sustain higher degrees of saturation and hydrostatic pressure. Concrete Arch Dams tend to exist in mountain gorge areas where aggregates for the concrete are less attainable. The alternative types of dams are Concrete Gravity Dams, Embankment Dams, and Concrete Slab & Buttress Dams.

    What is an Embankment Dam? An Embankment Dam is a freshwater-retaining structure comprising excavated rock, soil, or a combination of rock and soil from nearby geological formations.  In fact, Embankment Dams are known as an “Earthfill Dam” when filled with soil, and a “Rockfill Dam” when filled with rocks. Earthfill Dams are most common. The…
