STUDY OF THE SIQ AL-MUDHLIM CATCHMENT AREA & CLEARANCE OF THE COLLAPSE IN SIQ AL-MUDHLIM

Project start and end date: 2002-2003
Project Consultant: Middle East Engineering Management (MeeM)
Funding provided by: World Monuments Fund (WMF), Robert W. Wilson Challenge Grant; Jordan Telecom; US Embassy in Amman- Ambassador’s Fund for Cultural Preservation Awards 

The Siq al-Mudhlim Tunnel Project consisted of two phases.  Phase I, a study/survey of the Mudhlim area conducted following the collapse of the roof in December 2000.  The study showed how efficiently the Nabataean flash flood protection system took advantage of natural conditions and how it was integrated into the urban landscape of the city.  The Siq al-Mudhlim area was an integral part of the flood protection system together with the infrastructure in the Siq.  The diversion of the runoff water from upper Wadi Musa through the tunnel into Wadi Mudhlim and Wadi Mataha was essential to protect visitors, and monuments in the Siq.
 
In order to stabilise the conditions in the area of study, improve safety and minimise the damaging effects of flash floods to the tunnel, monuments and the immediate surrounding environment, the survey determined that the following measures needed to be implemented urgently: clearance of the collapse within the Siq al-Mudhlim tunnel, the clearance of the roof of the tunnel, the construction of three check dams to reduce the speed of flash floods, the construction of a detention basin (pond), and the construction of two dams.
 

        

In Phase II of the project one of the recommendations of the Siq al-Mudhlim survey, that of clearing the tunnel after its collapse was implemented in 2003.  The clearance of debris and stabilisation of the Siq’s tunnel bed was the first and most essential stage of the full-scale preservation project recommended in the survey and allowed for the resumption of water flow to serve its original purpose as it did during the Nabataean era, by reducing the possibility of floodwater flowing into the Siq and endangering visitors and monuments.
 
The next stage in the project, for which funds are required (Click here to view future projects) will involve stabilisation of the conditions in the tunnel, and the clearance and treatment of the roof of the tunnel to improve safety and to minimise the threat of future collapses.
 
A report on the project was published in the Annual of the Department of Antiquities of Jordan (ADAJ), volume 48 (2004).
