Unraveling the Links Between Dams and Landslides: Lessons Learned from a Devastating Case Study in Iran

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

In recent years, there has been a surge in the construction of dams, either to meet the growing demand for water or to generate power. However, these dams have raised concerns about their impact 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.

The study analyzed satellite data from the region and found 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 the reservoir increased. The researchers published their findings in Engineering Geology, indicating that dam construction raises local water tables, making hillside soil more susceptible to movement and ultimately leading to activated ancient landslides.

The study serves as a warning to dam engineers about potential risks associated with reservoir filling and its impact on nearby slopes. By understanding and mitigating these risks, we can better protect communities and infrastructure from potentially devastating consequences of landslides triggered by dam construction.

In conclusion, while dams are essential for meeting our energy needs or addressing water shortages, it is crucial that we consider their potential environmental impacts before constructing them. The recent study highlights how even seemingly small changes brought about by reservoir filling can have significant consequences on surrounding areas’ stability. Therefore, engineers must take proactive steps to minimize these risks when designing and building new infrastructure projects involving water storage or generation facilities.
