The wadi takes its name from the sidr tree, Ziziphus spina-christi, common in the Hajar Mountains and prized for the honey produced from its flowers.

[1] It is a fertile agricultural area traditionally home to members of the Mazari tribe.

[3] Although all of the Hajar Mountain wadis are prone to flash floods, Wadi Sidr is exceptionally so and is cited as having the highest potential for flash flooding (alongside Ain Al Faydah in Jebel Hafeet) in the Emirates.

[4] Wadi Sidr is also the watercourse with maximum flooding in the Emirates.

[5] Geologically, Wadi Sidr passes from areas of sedimentary rock through metamorphic and altered gabbroic rocks, complicated by thrust planes.
