Types of Dams Classification of Dam Types. A coffer dam is usually constructed on the upstream of the main dam to divert water into a diversion tunnel (or channel) during the construction of the dam. When the flow in the river during construction of the dam is not much, the site is usually enclosed by the coffer dam and pumped dry. Sometimes a coffer dam on the downstream of the dam is also required., Water Power & Dam Construction - Download as PDF File (.pdf), Text File (.txt) or read online. June 2009.
