Thursday, May 10: Here’s my pic-a-day for water. This is a falaj running on top of a 15-foot-high wall around the date palm plantations at Birkat al Mouz, near the University of Nizwa, in Oman.
Falaj is the Arabic word for a channel used to irrigate palm plantations and farm fields. These channels often run for many kilometers, from the source to the plantation in outlying farms and villages. It’s estimated that 70% of the water used in Oman is delivered by aflaj (the plural of falaj). The aquifers deep in the mountains contain surprising amounts of water, allowing springs and streams to flow months after the last rainfall (from Oman Off-Road).
