Alamut is a region in Iran including western and eastern parts in the western edge of the Alborz (Elburz) range, between the dry and barren plain of Qazvin in the south and the densely forested slopes of the Mazandaran province in the north. Having ample rivers, the Alamut valley has released inhabitants from worries about shortage in provided water. The heavy seasonal rainfalls, and adequate snowfall in winter replenish the origins of abundant water resources. Innumerable large and small lakes such as Ovan and Alebon are counted as the region's water resources.
