Sivand Dam

Sivand Dam(Persian:سد سیوند) is adambuilt in 2007 inFars Province,Iran.Named after the nearby town ofSivandlocated northwest ofShiraz,it was the center of worldwide concern because of the flooding it would cause in historical andarchaeologicallyrich areas ofAncient Persiaand possible harm it may cause to the nearbyUNESCOWorld Heritage SitesofPersepolisandPasargadae.

Planning and history

The Iranian government planned Sivand Dam for over 10 years, with a location on the Polvar River in theTangeh Bolaghi(Bolaghi Gorge) in between the ruins of Persepolis and Pasargadae. Intended to allowirrigationin the arid region, the planning and initial site construction began in 1992, then was stopped for further planning and was reactivated in 2003.

For the first decade, much of the planning was not made public; Iran's ownIranian Cultural Heritage Organization(ICHO) was not aware of total area of flooding until 2003. When the intentions for the dam were made public, international concern was raised regarding damage to any archaeological sites, particularly the two World Heritage Sites. Rumors spread that the dam would place the two ruins under water, spurring outcry and petitions of concerned experts and individuals. Scientists with the dam project dismissed the rumors outright, and Iranian officials pointed some blame for the rumors on the political opposition parties from outside Iran. Iranian Ministry of Energy studies have placed the furthest reaches of the lake approximately 7 kilometers to south of the plain of Murqab; that is 9 kilometers from Pasargadae and more than 70 kilometers from Persepolis.

However, Iranian officials from the Ministry of Energy and ICHO did acknowledge that the lake will flood 130 Persian archeological sites and invited international teams to help excavate the area before construction commenced. In 2004, theUnited Nationsissued an urgent international appeal for archaeologists to join the domestic effort to unearth and record what they could before the flooding. Teams fromGermany,France,Italy,Japan,Poland,and theUnited Statesresponded to the request for help.

One consequence of the dam's construction was an opportunity for extensive archaeological work in a historically rich area in a short amount of time. The oldest sites the international teams found were caves inhabited about 7,000 years ago.The archaeologists uncovered a narrow 9-mile dirt road believed to be the Royal Passage of theAchaemenids,connecting the two ancient cities, that was in use until the 18th century.

The archaeological work caused the construction schedule of Sivand Dam to be pushed back. The area was originally supposed to be flooded by end of February 2006, but the discovery of an Achaemenid-era village and cemetery caused it to be delayed.

Potential effects on Pasargadae

Besides the certain flooding of 130 archaeological sites, larger concern has been levied at the dam's effect on nearby World Heritage Sites, particularly Pasargadae, an ancient capital of thePersian Empirebuilt byCyrus the Greatand the site of his tomb.

Experts involved with planning the dam deny this claim, noting that the site is well above and away from the eventual waterline. However, it is unknown how the dampness caused by the dam will affect the ruins. Archaeologists and scientists agree that the rise in humidity from the new lake will speed up the destruction of Pasargadae to some degree.Although no preliminary environmental research has been carried out to assess the effects of humidity upon the constructions at Pasargadae, the Ministry of Energy believes it could be compensated by controlling the water level of the dam reservoir.

In 2010, studies of the Pasargadae showed thatgroundwaterlevels in the area had risen as a result of the dam and lake. The higher groundwater levels and increased humidity were said to be directly affecting foundation failures and the forming of newer cracks in walls and platforms throughout the ruins.

Completion

Sivand Dam was completed in 2007,but the height of the lake behind it was delimited so that it would not harm the site of Cyrus the Great Mausoleum. Dr. Shahriar Adl was active in preserving the site.
