From mid-March to April 2019, widespread flash flooding affected large parts of the Iranian plateau and its surroundings. Three major waves of rain and flooding over the course of two weeks led to severe flooding throughout much of Elam. Large dams were been overflowed, leading to the evacuation of numerous cities, towns, and villages.
The severity of the flooding was greatly increased by the conversion of dry river beds and flood routes for urban development without providing proper drainage infrastructure. According to an Iranian government official, due to record rainfalls, more than 140 rivers burst their banks, including the Dez and Ulay rivers which flow into Elam. Water accumulated in the Dez and Ulay dams so severely that the Ulay dam's reservoir flow reached to 8400m³/sec. As the dams reached their maximum capacity, the Ministry of Power opened the dams to discharge excess water.
The impact of the flooding was heightened because of the Nawruz holiday; many people were traveling and became trapped on roads and highways due to flash flooding. Approximately 36% of Elam's national road network was damaged. The floods caused more than half a billion USD (2019) in damages; a large portion of this was due to agricultural losses, which reached an estimated $138.2 million USD.
Civil and armed forces have been mobilized since 24 March.
