Évaluation de l’érosion hydrique dans des bassins versants de la zone semi-aride tunisienne avec les modèles RUSLE et MUSLE couplés à un Système d’information géographique

Abstract: L’érosion hydrique est une préoccupation agronomique, économique et environnementale importante en milieu semi-aride méditerranéen. Le choix de la méthode pour l’estimer dépend des données disponibles et des conditions de la zone d’étude. Cet article vise à quantifier et spatialiser l’érosion hydrique en utilisant l’équation universelle des pertes en sol (Universal Soil Loss Equation [USLE]) dans ses versions modifiée (Modified − MUSLE) et révisée (Revised − RUSLE) et couplées à un Système d’information géogra… Show more

“…However, owing to the unsatisfactory predictions (see section 3), the models were calibrated taking into account the most sensitive input parameters (CN for the SCS‐CN model, and the C‐factor for the MUSLE and USLE‐M equations). The C‐factor is the most used calibration parameter for USLE‐family erosion models (Biddoccu et al, 2020; Hammad et al, 2004; Khemiri & Jebari, 2021). For this reason, the hydrological effects of mulching practice were taken into account by tuning this factor.…”

“…This revision extended the scope of calculations to larger catchments with different land-use types. The spatial estimation approach of RUSLE is used in many studies to quantify the average annual soil losses due to water erosion, including in Mediterranean or semiarid areas (Al Zitawi, 2006;Kouli, Soupios and Vallianatos, 2008;Khemiri and Jebari, 2021). In line with the Kingdom's erosion control program, the model is also preferred for studies in Morocco (Meliho et al, 2016;Hara et al, 2020;Manaouch, Zouagui and Fenjiro, 2021).…”

“…Pour apprécier l'érosion hydrique de la région d'étude, nous nous sommes basés sur l'équation universelle révisée par Renard et al [6] (RUSLE). La RUSLE, version dérivée et informatisée de l'USLE, a été employée par de nombreux auteurs dans la région méditerranéenne (Khemiri et al [24]) et en Chine (Zhang et al [25]).…”
