Seybouse

Seybouse is a river in northeastern Algeria, close to the Tunisian border. It was known as the Ubus in Roman times. The river flows for around 225 kilometers through the provinces of Guelma and Annaba. It begins in Medjez Amar, northwest of Guelma Province, in the Tell Atlas. It empties into the Mediterranean Sea in Seybouse (formerly Joannonville), which is located southeast of Annaba. Its mouth is located approximately north of Sidi Salem, the site of Hippo Regius, where Saint Augustine resided from 391 to 430 AD.

The Seybouse is utilized for agricultural irrigation, although it is increasingly contaminated as a result of industrial activities. A number of large-scale industrial activities can be found along the Seybouse River. Hydrocarbon processing plants are of particular concern. This industry produces a lot of pollution, which gets into the groundwater and contaminates bodies of water. The contaminated water is then unfit for human consumption and poses a threat to wildlife survival.
