Most dams have a section called a spillway or weir over which or through which it is intended that water will flow either intermittently or continuously. Dams are classified according to structure, intended purpose or height.

According to the height, dams can be categorised as large dams and major dams or alternatively as low dams, medium height dams and high dams
