Water erosion in general is considered a natural danger that worsens with passing of years, and this is in the absence of human awareness and taking the necessary preventive measures to manage areas exposed to erosion. Most studies on water erosion have been subject to one framework, which is the evaluation of water erosion. This research contributed to the identification of soil erosion-prone areas in the sub-watershed of Boussellam and K’sob, Algeria, through the use of the Analytical Hierarchy Process (AHP), Fuzzy Boolean Modeling and the Modified Global Soil Loss Equation (RUSLE). A group of factors that affect soil erosion were used (Curvature, Slope, Aspect, Elevation, Rainfall Erosivity, Land use land cover, Drainage Density, K factor/Soil, Lithology, NDWI, Factor Ls, NDVI, Factor P, C Factor). Water erosion conditioning factors were integrated and erosion risk maps were extracted using the Geographic Information System. The study results, after using the RUSLE, fuzzy and AHP models, indicate areas with very high erosion risks occupied 12.91%, 12.98% and 9.49%, respectively, of the study area, and with the help of Receiver Operating Characteristics curves the risk maps were validated. Water erosion under the curve (AUC) and the results revealed that the models showed good predictive capabilities in determining soil erosion susceptibility zones with AUC values of 0.783, 0.806, and 0.644 for the AHP, fuzzy logic and RUSLE models, respectively. This study contributed to identifying the area’s most vulnerable to water erosion to help decision-makers to intervene quickly and take the essential strategies to reduce this problem in the research area.

Le dimensionnement des ouvrages hydrauliques dans les bassins non jaugés est basé sur des débits de crues calculés généralement par des formules empiriques Pour cela, plusieurs formules empiriques ont été développées, on cite : TURAZZA, MAC MATH, SOKOLOVSKY, GIANDOTTI, etc. Ces formules fond appel à des méthodes de prédétermination basées sur les précipitations journalières maximales en tenant compte des différentes caractéristiques du bassin versant y compris l'état de son couvert végétal sans tenir compte de ses changements saisonniers.

This study aimed to estimate the annual soil loss in the Boussellam watershed in the northeast of Algeria, using the Revised Universal Soil Loss Equation (RUSLE), geographic information system (GIS), and remote sensing. RUSLE model has been used for modeling the main factors involved in erosive phenomena. This basin is characterized by an altitude ranging from 189 m to 1757 m, with an average of 931 m and a slope ranging between 0 and 266 % with an average of 18 %. Results showed that the average erosivity factor R is 68 (MJ.mm/ha.h.an) with a maximum value of 140 (MJ.mm/ha.h.an). The soil erodibility factor K ranges from 0.04 to 0.21 with an average of 0.11 (t.h.ha)/(MJ.ha.mm). The LS topographic factor ranges from 0 to 216 with an average of 16. The mean P factor is estimated to be 0.77, and the average C factor is 0.076. The combination of the different maps of these parameters made it possible to deduce the erosion map from which, it appears that the phenomenon of erosion mainly affects the northern part of the basin with an average of 258 (t/ha/year) for July 2015.

The objective of this work is to study the evolution of soil erosion in the Boussellam watershed in the northeast of Algeria, using the Revised Universal Soil Loss Equation (RUSLE), geographic information system (GIS), and remote sensing. RUSLE model has been used for modeling the main factors involved in erosive phenomena. This basin covers an area of 4151 km² of elongated shape and low relief. It is characterized by an altitude ranging from 189 m to 1757 m, with an average of 931 m and a slope ranging between 0 and 266 % with an average of 18 %. Results showed that the average erosivity factor R is 68 (MJ.mm/ha.h.an) with a maximum value of 140 (MJ.mm/ha.h.an). The soil erodibility factor K ranges from 0.04 to 0.21 with an average of 0.11 (t.h.ha)/(MJ.ha.mm). The LS topographic factor ranges from 0 to 216 with an average of 16. The mean P factor is estimated to be 0.77, and the average C factor is 0.076. The combination of the different maps of these parameters made it possible to deduce the erosion map from which, it appears that the phenomenon of erosion mainly affects the northern part of the basin with an average of 258 (t/ha/year) for July 2015. These maps can be particularly useful in pinpointing potential areas of increased erosion risk underpinning targeted investigation and management action to support soil conservation for improved food and water security in this important watershed.

In order to take measures to control soil erosion, it is necessary to estimate soil losses over the area of interest. Soil loss due to soil erosion can be estimated using predictive models such as the Universal Soil Loss Equation (USLE) and the Revised Universal Soil Loss Equation (RUSLE). The accuracy of these models depends on the parameters used in the equations. One of the most important parameters in the equations used in both models is the C-factor which represents the effects of vegetation and other land cover types. Land cover estimation by remote sensing image interpretation uses the Standard Difference Vegetation Index (NDVI), an indicator showing vegetation cover. The purpose of this study is to estimate the C-factor values for the Boussellam watershed using satellite images. The final C-factor map was generated using the regression equation in the Spatial Analyst tool of the Arcgis 10.3 software. It is found that most of the basin is characterized by C-factor values between 0.6 and 0.8 (45.29% of the total catchment area). Keywords: Erosion, RUSLE, USLE, Factor C, Landsat, NDVI

The study includes the simulation of the hydrological behavior of the watershed during extreme precipitation in the first place using Hec-Hms, which takes into account the losses (infiltration losses, retention or evapotranspiration), the flow rate that takes into account surface runoff, storage, pressure drop and water behavior when it is in the bed of a watercourse. Secondly, its sedimentological behaviour with the aim of estimating solid inputs reaching the outlet of this watershed during the same precipitations. Keywords:watershed, Labiodwadi, Extreme floods, Hec-Hms, Modelling, Rainfall-Runoff, Solid transport.

The sediment transport is a complex phenomenon by its intermittent nature, randomness and by its spatio-temporal discontinuity. By reason of its scale, it constitutes a major constraint for develop-ment; it decreases storage capacity of dams and degrades state of ancillary structures. The study consists in modelling the transport of sediments by HEC-RAS software in wadi Chem-ora (Batna, Algeria). In order to do this, we have used hydrometric data (liquid flows, and solid flows) recorded at level of the four hydrometric stations existing in watershed of wadi Chemora, the MNT of the wadi and lithologic characteristics of the wadi. In the analyses of results we used the parameters from two different floods (the first one involved the whole watershed and the second – a part of the basin) along of system of wadi Chemora (wadi Chemora and its tributaries): sediment transport capacity, volume of sediments delivered to and leav-ing the system and areas sensitive to erosion and sedimentation. Key words: deposition, erosion, HEC-RAS, modelling, sediment transport, wadi Chemora, watershed
