Connection found between 2019 Iranian landslide and construction of dam, say scientists

Recently, there has been a sharp rise in the construction of dams worldwide. These dams are either built to fulfill the growing demand for water or to generate electricity. However, concerns have been raised regarding the potential impact of these dams on the environment. A recent study has shed light on the link between dam construction and increased landslide activity.

One such incident occurred in March 2019 when a landslide devastated Hoseynabad-e Kalpush village in north-central Iran, causing damage to 300 houses and cutting off access to the nearby dam. Local authorities initially attributed the landslide to heavy rainfall and denied any connection to the dam. However, scientists from the German Research Centre for Geosciences have found evidence to the contrary.

Analysis of satellite data from the region revealed that the stable slope where the landslide occurred began to show movement after the reservoir behind the dam started filling with water in 2013. Over time, land movement progressed from lower portions of the slope to higher ones as water levels in reservoirs rose. The research findings published in Engineering Geology suggest that water accumulation in dams raises local water tables, making soil more susceptible to movement, ultimately leading to ancient landslides being triggered.

This study serves as a warning for engineers who design and build these massive structures. It highlights how crucial it is for them to consider potential risks associated with reservoir filling and its impact on nearby slopes. By understanding these risks and taking steps to mitigate them, we can protect communities and infrastructure better from potentially devastating consequences of landslides caused by dam construction.
