Abstract In Tunisia, soil and water conservation interventions are among the most practicable strategies to prevent mitigate rainwater losses through surface runoff consequential erosion of fertile soils. this study, a small terraced agricultural catchment (Sbaihia) was used as an experimental site analyze parameterize effects bench terraces on sediment yield using Soil Water Assessment Tool. Model calibration validation performed, taking advantage from high‐quality daily data 1994 2000...
Abstract Land use planning (LUP) to achieve Degradation Neutrality (LDN) needs methods and tools that support the identification of best LUP solutions in terms transitions from current degradative land (LU) management (LM) practices better LU LM options. A crucial need is context specific sustainable (SLM) Addressing this must aim at not only reversing/recovering past degradation (e.g., via restoration or rehabilitation hotspots), but also avoiding “new” possibly caused by unsuitable LM....
Introduction Analyzing the hydrological dynamics and assessing impact of Soil Water Conservation (SWC) techniques provides crucial insights for developing region-specific conservation strategies advancing effective watershed management. Methods A multi-objective calibration concept was applied to Assessment Tool (SWAT) model, where simultaneous across andits sub-watersheds performed using multiple objective criteria. This study investigates SWC measures on Merguellil watershed, Central...
The Mediterranean region is experiencing severe environmental pressures due to climate change, population growth, agricultural intensification, and desertification. Impacts will be exacerbated in the coming decades require adaptation strategies increase resilience of ecosystems counteract land degradation. Throughout Mediterranean, desertification combined with reduced freshwater availability main factors limiting production, driving need for alternative low-water demanding crops. Some...
In northwestern Tunisia, floods are the most widespread natural hazard. Indeed, this problem is posed seriously in Medjerda basin. fact, plain of Jendouba - Bou Salem affected area by plague. It has form a shallows that collects runoff water and promotes flood extent duration. So main objective study to determine hydraulic hazard through mapping February 2015 event which urban peri-urban landscape plain. The was determined HEC-RAS model. It's one popular free models developed Hydrological...
Understanding and long-term assessment of the efficacy soil water conservation (SWC) techniques is essential for sustainable watershed management. There have been few studies measuring impact SWC on erosion at catchment scale due to a lack historical data. This research aims measure analyze interventions sediment yield using Soil Water Assessment Tool (SWAT) in Wadi Rmel between 2000 2020. The study approach has simultaneously three main aspects: (i) temporally dynamic, (ii) large-scale...
Systematic biases in general circulation models (GCM) and regional climate (RCM) impede their direct use change impact research. Hence, the bias correction of GCM-RCMs outputs is a primary step such studies. This study compares potential two methods (the method from third phase Inter-Sectoral Impact Model Intercomparison Project (ISIMIP3) Detrended Quantile Matching (DQM)) applied to raw daily data minimum maximum air temperatures precipitation, Cap-Bon region, eight GCM-RCM combinations....
Soil degradation and erosion in semi-arid regions can significantly impact agricultural development, environmental sustainability, hydrological balance. Understanding the impacts of land use changes soil water conservation (SWC) technique implementation on sediment yield is critical to planning effective watershed management. This study aims evaluate Merguellil (Central Tunisia) over last forty years. To achieve this, remote sensing techniques a geographic information system (GIS) will be...
Climate change significantly impacts watershed hydrology, altering water supplies, natural disasters, and eco-hydrologic processes. These effects vary geographically, with some regions facing severe droughts while others experience increased precipitation flooding. influences atmospheric evaporation demand, patterns, vegetation composition, streamflow characteristics, groundwater dynamics. The temperature increases rainfall changes in watersheds can lead to potential evapotranspiration...
This study investigates the impact of conservation practices, specifically mulching and terracing, on soil erosion in Kamech watershed (2.6 km²) situated Cap Bon region northeastern Tunisia, under both current future climate scenarios. Utilizing Soil Water Assessment Tool (SWAT) model, research evaluates effectiveness these Best Management Practices (BMPs) reducing loss, revealing significant reductions 1.5 t ha⁻¹ yr⁻¹ for 2 terracing. The findings indicate that practices play a crucial role...
Abstract Soil erosion is a severe environmental concern arising from intensive agricultural uses, land degradation, and anthropogenic activities. This problem threatens productivity sustainable development, particularly in emerging countries. Therefore, evaluating soil essential conservation, planning, management on watershed or basin scale. study aims to assess the of loss El Gouazine Watershed, central Tunisia, using water assessment tool (SWAT). We define impact conservation...
L'étude a pour finalité de chercher une approche à la fois analytique et synthétique des modalités l'érosion due au ruissellement du transport sédiments afin permettre cartographie quantification pertes en sol dans deux sous-bassins bassin Merguellil Amont, situés région Haffouz centre Tunisie.Les modèles USLE, MUSLE RUSLE sont couramment utilisés calculer perte annuelle moyenne par unité surface terrestre résultant nappe rigoles. Cette dépend plusieurs facteurs : l'érosivité pluies,...
As a semi-arid Mediterranean country, Tunisia is affected by the impacts of climate change, particularly coastal regions like Cap-Bon. Irregular rainfall, rising temperatures and recurrence extreme events are all indicators that affect ecosystems populations make them more vulnerable to influence climatic variables. Therefore, an analysis trends variables can contribute facilitating development effective adaptation strategies. In this matter, study was conducted assess homogeneity minimum...
Groundwater is the main source of water in studied area; therefore, it significantly requested all activities inhabitants. These natural resources are affected by some drivers especially Land Use/Land Cover (LULC) and Climate Change. A dynamics study crucial for any global environmental change evaluation. For instance, a given place, its could affect considerably cycle components. Therefore, knowledge effects LULC on groundwater recharge then key management system, particular decision makers...
Understanding, mapping and modelling of water erosion process become a serious concern for soil conservation practitioners, as well decision-makers concerned with natural resource management agricultural policies. The current research aims to map quantify rates in the Upper-valley Medjerda Watershed Northern Tunisia. A systematic method incorporating three models (RUSLE: revised loss equation, FAO: food organization, EPM: potential model) was adopted. Indeed, multi-sources earth observation...
