One of the critical areas of the coury’s subsidence and area is affected by subsidence and area and the devastating effects on the subsidence of the Hashtgerd plain of Alborz province, said the head of the coury’s Surveying Organization.
According to RCO News Agency, Masoumeh Amiq Pay, referring to the significa increase in subsidence rates in Mehrshahr and Nazarabad Karaj, said: According to the latest calculations of the coury’s mapping organization, although the overall subsidence process in Alborz province’s agricultural land has declined, we are witnessing an increase in subsidence rates in Mehrshahr and Nazarabad cities to supply water to the industry. And it has reached a maximum rate of 5 cm per year.
He added: “It is noteworthy that this high rate of subsidence has occurred in resideial areas due to pressure on groundwater resources to supply drinking water and has caused devastating effects on local structures.” Mehrshahr is one of the most populous areas of Karaj city in Alborz province and is immigra due to its proximity to Tehran and a relatively reasonable housing price, so that the population growth process is estimated faster than urban standards.
Amiqpi noted: Mehrshahr area of Karaj mainly uses deep and semi -esseial wells to supply drinking water. These wells are harvested from the underground aquifers of the Karaj-Mehr plain.
The head of the Mapping Bureau of the Mapping Organization described Nazarabad as one of the other subsidence cities with high rates of Alborz province and coinued: Although the subsidence of Nazar Abad agricultural land has improved and decreased, since the highest volume of water has been supplied by Nazarabad.
According to the Public Relations Organization of the coury’s Mapping Organization, he added: Sepehr Industrial City, one of the most importa industrial towns in Alborz province, which has recely received the atteion of craftsmen, is also one of the unprecedeed increase in the unprecedeed rate of 5 cm per year. This town is an example of industrial developme with unnecessary pressure on groundwater resources. Cracking buildings and infrastructure, reducing the storage capacity of groundwater aquifers, and increasing the risk of flooding in the eve of heavy rainfall (due to reduced land permeability) are devastating effects of subsidence.
Amigh Pay emphasized: It is necessary to pay immediate atteion. Urban and industrial developme tailored to the region’s water resources, optimized harvesting of wells by reducing consumption and preveing illegal drilling, installing smart meters to manage consumption, developing refined efflue for non -drinking consumption, and careful monitoring of the amou of subsidence and monitoring with new technologies.
He emphasized that if the proper urban planning, the problems of drinking water and subsidence of the region will be exacerbated.
