At the same time as the start of the rainy season in Iran, the forecast for an increase in the amount of rainfall in certain areas raised the question of whether or not the El Nino phenomenon can help reduce the water shortage crisis. Mohammad Reza Kavianpour, head of the Water Research Institute, said the fall rainfall in some parts of the country could be 30 to 70 percent more than normal. But an increase in the amount of precipitation does not necessarily mean an increase in the useful water resources. In Khuzestan, the director general of meteorology of the province said that El Nino can change the precipitation pattern in the cold half of the year and increase the possibility of heavy rains and showers. But he said that even a rainy autumn does not mean solving Iran's long-term water shortage problem, and water resources must be managed by considering dry scenarios.
