Wikipedia Overview

From mid-March to April 2019 widespread flash flooding affected large parts of Iran, most severely in Golestan, Fars, Khuzestan, Lorestan, and other provinces. Iran has been hit by three major waves of rain and flooding over the course of two weeks which led to flooding in at least 26 of Iran's 31 provinces and at least 70 people died nationwide as of 6 April, according to the officials. The first wave of rain began on 17 March, leading to flooding in two northern provinces, Golestan and Mazandaran with the former province receiving as much as 70 percent of its average annual rainfall in single day. Several large dams have been overflowed, particularly in Khuzestan and Golestan, therefore many villages and several cities have been evacuated. About 1,900 cities and villages across country have been damaged by severe floods as well as hundreds of millions of dollars of damage to water and agriculture infrastructure. 78 roads were blocked and the reliability of 84 bridges was questioned.
