\section*{Qanat}

[[!redirects qanat]]

\hypertarget{idea}{}\subsection*{{Idea}}\label{idea}

A \emph{\textbf{qanat}} is an underground irrigation system fed by springs or groundwater. They are common throughout the Middle East, and they can be found all the way from the Gobi Desert to Spain. They have different names in different cultures: in Berber Arabic, they're called \emph{foggara}; in Persian, \emph{qarez}; in Spanish, \emph{acequia}, and in Turkish, \emph{qanat}.

Above is an image created by \href{http://www.suehutton.co.uk/}{Sue Hutton} showing a cross-section of a \emph{qanat} in Oman. Structures of this type collect water in the rock, sand, and gravel aquifers at the edges of the mountainous region in northern Oman. They run underground for kilometers, and emerge at oases. In Oman they are also known as \emph{dawoodi} or \emph{iddi falaj}.

Besides its use in irrigation, a \emph{qanat} can also be used together with a [[windcatcher]] to cool a building without using any electrical power.

Many \emph{qanat} in Iraq were destroyed during the American invasion.
