[1] Boudouaou Valley, known for its riverbed largely free from schist and earthy deposits, shares this unique feature with nearby rivers such as Arabiyah, Mghaldan, Boumerdès, and Isser.

[2] This characteristic allows for the extraction of sand and gravel, which are essential materials in producing mortar and concrete.

[3][4] Acting as a natural corridor, the valley ranges in width from 5 to 600 meters and gradually descends from its meeting point with the Bouzegza Keddara in the municipality of Kadara, at the base of Mount Bouzegza in the south, until it reaches the Mediterranean Sea east of Boumerdès City.

[6] During the rainy season, the increased water flow necessitated the creation of passageways and bridges to facilitate movement for residents of surrounding villages and neighborhoods situated along both banks.

[19] The Boudouaou Valley intersects with several national roads as it traverses Boumerdès Province in the Khachna Mountains.
