Brief synthesisThe Aflaj Irrigation System of Oman is a serial property, with five individual component parts - Falaj Al Jeela, Falaj Muyasser, Falaj Daris, Falaj Malki and Falaj Khatmein. The settlements and agricultural areas also represent traditional land uses which rely on water systems. Without benefit of modern tools and equipment, the individual falaj systems carried water over many kilometres powered by gravity alone. Criterion (v): The collection of Aflaj irrigation systems represents some 3,000 still functioning systems in Oman. Traditional management systems are still strong and an important factor in the property’s successful management.
