Abstract: (355 Views)
Today, the issue of land subsidence has emerged as a significant and critical factor jeopardizing both surface and subsurface structures within the nation, particularly in the northwest region. This situation necessitates the preservation of such infrastructures. Considering the vast expanse of the electricity distribution network in East Azerbaijan Province—encompassing an area of 45,000 square kilometers, a network length of 26,000 kilometers, and serving 930 thousand subscribers—the apprehensions regarding the existence of potential risks are justified. This extensive network is deemed one of the most sensitive and essential assets within the province in relation to the occurrence of land subsidence. Given this high level of sensitivity, it becomes imperative to identify regions susceptible to subsidence and to assess the vulnerability of the electricity distribution networks while implementing necessary measures to enhance resilience against this phenomenon. The objective of this research is to delineate the vulnerable regions. Conversely, land subsidence poses threats to power grid installations within East Azerbaijan Province. In this study, ArcGIS 10.7 and Super Decision software were employed to generate the information layers; furthermore, to ensure appropriate homogeneity among the various layers, the input data was standardized, and the Analytical Network Process (ANP) was utilized. The findings of the research indicate the existence of areas characterized by a high risk of subsidence, covering an expanse of 1,981 square kilometers, alongside regions with an exceedingly high risk of subsidence, encompassing 268 square kilometers, extending from the northwest to the southeast of the province (including the cities of Marand, Shabestar, Tabriz, Bostan Abad, Mirage, and the central area). Additionally, in the southwestern municipalities of the province (namely Banab, Malekan, and Ajabshir), there are hazardous zones where the threat of subsidence and potential damage to electrical installations necessitate serious consideration. An examination of the maps and data further reveals that a majority of groundwater extraction wells are situated in high-risk areas with considerable density. Investigations also indicate that agricultural activities predominantly characterize land use in high-risk areas, wherein the most significant drop in groundwater levels has been observed. In this investigation, by superimposing the province's power transmission network map with the final subsidence risk zoning map, it was ascertained that portions of the province's power grid facilities are located within high-risk zones concerning land subsidence.
