Naser Karmi, a climatologist and environmental expert, said that drought and floods are not only not mutually exclusive, but that drought increases the risk of floods by destroying vegetation and soil texture. According to him, the change in the rainfall pattern in Iran has caused the rainfall to appear more frequently in the form of severe floods and the water is quickly out of reach.
Referring to the flooding of Tehran's streets, Karami added that the indiscriminate development of construction, the weakness of the runoff management infrastructure and the lack of integrated urban management made the capital vulnerable to heavy rains. He emphasized that despite the previous warnings about the possibility of floods, the dispersion of responsibilities between different institutions prevented preventive measures and an effective response.
