Unprecedented heavy rains have caused floods in various parts of Iran since March 19. The floods claimed the lives of at least 19 people and injured more.
A large number of people were displaced and a huge damage was inflicted on infrastructures.
Rouhani's government has vowed to compensate for the damaged as soon as possible, and establish a committee to investigate the causes of floods.
At the end of his trip to Golestan, he will visit the other northern flood-stricken province, Mazandaran.
Flash rains also caused dam overflows and river floods, damaging vast areas of farms and gardens.
A number of heads of states and foreign ambassadors have sympathized with affected people and offered condolences to Iranian officials.
