The Soummam constitutes a dense and well-supplied hydrographic network, particularly in its part situated in the Tellian Atlas: Djurdjura, Babors and Bibans.
The Béni Mansour-Bejaïa line is a regional railway that closely follows this river valley and connects to the national rail network in the municipality of Boudjellil.
Between the Akfadou-Gouraya set in the north, the Biban chain (the historic territory of the Ait Abbas) in the south-east and the Sahel-Djurdjura valley (Tazmalt commune) in the south-west.
This area is broken down into small pedological units: the flysch prevails in Akbou, the sandstone is predominant in El Kseur.
The municipalities of Amizour, El Kseur, Ouzellaguen and Timezrit have vast areas suitable for rich crops such as market gardening and fruit growing.
