Abstract: (250 Views)
The occurrence of various threats both natural and human-induced can cause extensive damage to national infrastructure. One of the most critical components of such infrastructure is dams. Dam safety is regarded as one of the most important issues in the dam engineering industry during the stages of design, construction, and operation. The objective of this study was to assess the risk and vulnerability of reservoir dam facilities to natural and anthropogenic hazards. In this research, the identification and evaluation of these vulnerabilities were carried out for the Balaroud Reservoir Dam using the RAMCAP methodology.
First, assets and specific threats related to dam construction and operation were identified and assessed. Subsequently, the severity of vulnerability of each identified asset to potential threats was evaluated. Finally, by calculating the risk value for each asset using the RAMCAP method, the assets of the Balaroud Reservoir Dam from water intake to transmission facilities were identified as vulnerable units. This classification enables the implementation of appropriate control measures prior to the occurrence of natural or human-induced disasters in order to reduce overall vulnerability.
Based on the average risk assessment results, seven high-risk assets were identified, including the powerhouse with a risk value of 509, the administrative–residential camp with a risk value of 470, the powerhouse control room with a risk value of 438, the diversion tunnel with a risk value of 413, the water intake with a risk value of 382, the dam reservoir with a risk value of 378, and the batching plant with a risk value of 372. Seven assets were classified as having moderate risk, including the tower crane, crane, water treatment plant, pump and drilling rig, concrete placing equipment, formworks, and the switchyard. The remaining assets were categorized as low-risk. It should be noted that the diesel generator, with a risk value of 150, was located at the threshold between low and moderate risk levels.
Considering the identified risks associated with the assets of the Balaroud Reservoir Dam, the provision of personnel training for preparedness before and after crisis events, equipment safety enhancement, and the implementation of appropriate measures for crisis management and control are considered essential.
