The watershed Sidi Salah, located in the north of Sfax (Tunisia), Knew an important water and soil conservation installations. These installations present certain operating anomalies that make them unable to well manage the hydric erosion phenomenon. This work aims to identify those anomalies and to characterize the responsible factors in order to promote the sustainable management of water and soil at the level of the watershed. The study was based on the photo-interpretation of the satellite images with high resolution, the field observation and the chemical analyses of the soil samples taken in various sites of the watershed. The results allowed us to reveal some anomalies as the loss of embankments and the destruction of the masonry installations. The responsible factors are mainly naturals, related to the turbulent water flows and the soft lithology of the soil rich in gypsum and limestone.

Abstract: (french)
Le bassin versant Sidi Salah, situé au Nord du gouvernorat de Sfax (Tunisie), a connu des aménagements de conservation des eaux et du sol assez importants. Ces ouvrages présentent certaines insuffisances qui les rendent incapables de bien contrôler le phénomène d'érosion hydrique. Le présent travail a pour objectif d'identifier ces anomalies et de caractériser les facteurs responsables de leur apparition afin d'assurer une gestion durable des eaux et du sol à l'échelle du bassin versant. L'étude s'est basée sur la photo-interprétation des images satellites à haute résolution, des observations sur terrain et des analyses chimiques des échantillons du sol prélevés à différents sites du bassin. Les résultats de l'étude ont permis de dévoiler comme anomalies la perte des ouvrages en remblai et la destruction des ouvrages en maçonneries. Les facteurs responsables sont, essentiellement, naturels liés à la turbulence des écoulements d'eau et à la lithologie tendre du milieu riche en gypse et en calcaire.
