Figure 3: Diagram of a qanat, developed in Islamic lands as a water management system used to provide a reliable supply of water to human settlements or for irrigation in hot, arid and semi-arid climates. (Source).
Figure 4: A pool at Aqiq, Saudi Arabia, one of dozens of rest and water stations on the pilgrim road from Iraq to Makkah. It still holds water more than a thousand years after it was constructed under the patronage of Zubaydah, the wife of caliph Harun al-Rashid. (Source).
Figure 5: The Albolafia noria, or waterwheel, is the last vestige of an array of mills and dams built on the Guadalquivir River in Cordoba between the 8th and 10th centuries as it appears in its present condition. (Source).
Figure 6: The shaduf was known in ancient times in Egypt and Assyria. It consists of a long beam supported between two pillars by a wooden horizontal bar. A counterweight was attached to the short arm of the beam. A bucket suspended by a rope or a pole was attached to the long arm of the beam. The bucket was lowered into the water by bearing down on the rope/pole and the counterweight raised the full bucket. The shaduf is still used in Egypt. See: Sandra Postel, "Egypt's Nile Valley Basin Irrigation". (Source).

Figure 8: The largest norias or water wheels in the world, with a diameter of about 20 meters, exist on the Orontes River in Hama, Syria. Norias (na'ura in Arabic, pl. nawa'ir) are machines for lifting water into an aqueduct using energy derived from the water's flow. It consists of an undershot waterwheel to which are fixed a series of containers that lift water from the river to the aqueduct at a higher level. (Source).

Figure 11: Aerial view of lines of qanats leading to Firuzabad in Iran. The rows of small holes resembling pockmarks reveal the presence of several qanat systems below the surface: each hole is the top of a ventilation shaft. The walls of the craters protect the shafts and the tunnel below from erosional damage from the inflow of water during a heavy rainstorm. (Source).
