“…The sludge contained therein is weighed after drying in a special oven for 30 min at a temperature of 110°C. This method was conducted to determine the sediment concentrations in a standard procedure established in the national territory and by many world agencies [ACHITE, OUILLON 2007;KHANCHOUL et al 2007].…”

“…The scatter plots have shown a trend with a changing of the direction of the regression line and by applying the division of datasets into two regression lines; we could have an improvement of the coefficients of correlation (R). This method was applied in Algeria by various authors such as KHANCHOUL et al [2007], ACHITE and OUILLON [2007], YAHIAOUI et al [2011].…”

Erosion is a major phenomenon that causes damage not only to soil and agriculture, but also to the quality of the water amounting to tonnes of matter annually transported on the earth's surface. This fact has attracted the interest of researchers to understand its mechanism and explain its causes and consequences. This work is a comparative study of water erosion in the two semi-arid catchments of Wadi Soultez and Wadi Reboa; located in the North-East of Algeria. The approach adopted for the quantification of sediment transport consists on researching the best regressive model to represent the statistical relation between the sediment yield and the measured water discharge at different scales: annual, seasonal and monthly. The available data cover 27 years from 1985-2012. The results show that the power model has given the best correlation coefficient. Results have indicated that Wadi Reboa transported an average of 14.66 hm3 of water and 0.25 million tonnes of sediments annually. While Wadi Soultez has transported 4.2 hm3 of water and 0.11 million tonnes of sediments annually. At a seasonal scale, sediment amounts have showed significant water erosion in autumn with around 44% and secondarily in the spring with 29% in Wadi Soultez. Unlike Wadi Reboa, sediment transport represents 32% and 46% in autumn and spring respectively. Based on the obtained sediment amounts; it is found that the physical factors: such as steep reliefs, vulnerable lithological nature of rocks and poor vegetal cover, have significantly contributed in accelerating soil erosion.

“…Jansson (1985) suggested the use of mean loads in discharge classes to develop sediment rating curves, since by definition, a regression curve should go through the mean concentrations at every water discharge. Khanchoul et al (2007) used the discharge class method to calculate sediment load in two drainage basins in NE Algeria where sediment concentrations were extremely scattered. Sediment yields in the two basins were calculated, and were compared during different seasons and months.…”

Khanchoul, K. and Jansson, M.B., 2008: Sediment rating curves developed on stage and seasonal means in discharge classes for the Mellah wadi, Algeria. Geogr. Ann., 90 A (3): 227-236.ABSTRACT. The focus of the present study was to estimate suspended sediment load from the Mellah catchment (550 km 2 ) during storms. Suspended sediment rating curves were developed on data from a 23-year period. The regression technique of this paper involves a division of data into dischargebased classes, the mean concentrations and discharges of which are used to develop power regressions through log-transformation. Sediment rating curves were also developed on means of data grouped into seasons and stages. Sediment loads estimated by rating curves uncorrected for bias involved underestimations of down to 9% compared with loads from measured concentrations. Correction for bias reduced underestimations to a range from 0.79 to 3%. Rating curves divided into rising and falling stages had the lowest underestimation and were used to estimate load during periods without concentration measurements. During the 23-year study period, the mean annual suspended sediment yield was 373 T/ km 2 . Sediment transport is dominated by winter storms accounting for 61% of the annual load. A high exponent 'b' of the power regression equations during the winter season confirms the intense geomorphic work by winter season storms caused by high intensity rainfall, low vegetation cover, and heavy machine activity in the fields.
