Classsification (Types) of Dam - Engineering Articles
Arch Dams ae very complex and complicated types of Dams. They make use of the horizontal arch action in place of weight to hold back water. They are best suited for sites where the dam is required to be very high and narrow. Rock fill Dams are formed of loose rocks and boulders piled in the river bed. A slab of reinforced concrete is often laid
Guidelines for Design of Dams
guidelines for the proper design of a dam. In order for a dam to safely fulfill its intended function, the dam must also be constructed, operated and maintained properly. Supervision of construction or reconstruction of the dam by a licensed professional engineer is required to insure that the dam will be built according to the approved plans.
