Circular Fields in Saudi Arabia by Jordan Border – December 4th, 2010
The green area in the upper right quadrant of this image is composed of many circular irrigated fields on the usually dry terrain of Saudi Arabia, near the Jordan border. The fields are situated around the settlement of Al Basayta.
The fields are able to flourish in the arid region due to center-pivot irrigation, also called circle irrigation, a method of crop irrigation in which equipment rotates around a pivot.
Central pivot irrigation is a form of overhead (sprinkler) irrigation consisting of several segments of pipe (usually galvanized steel or aluminium) joined together and supported by trusses, mounted on wheeled towers with sprinklers positioned along its length. The machine moves in a circular pattern and is fed with water from the pivot point at the center of the circle.
