“…This importance is explained in particular by the specific power at the full high edge of the wadi El-Hammam as well as by the high solid contribution in autumn. The extent of bed load is typical of Mediterranean mountains and semi-arid environments [26]. Thus, our values are close to those highlighted in Wales and Scotland, from where studies put forward values including between 2.9 and 44 Mg.km -2 .year -1 [27,28], very high values between 33.6 and 107.2 Mg.km -2 .…”

In Algeria, only the transport of suspended sediment is measured, the rate of bedload in the global transport of solids is estimated, approximately. Measures of bed load transport in the field are very costly, due to flow disturbances. As a result, evaluations of this type of sediment transport are difficult to carry out in the absence of databases. In this article, we tried to quantify this mode of transport at the wadi El-Hammam using the formula of Meyer-Peter and Müller. Formula that seems best adapted to the physical characteristics and flow conditions of the wadi studied. The results obtained show that the calculated bedload ratio is between 0.6 and 28% of the suspension. The quantities transported annually are very large and irregular as they vary from 2.3 to 32 Mg.km -2 .year -1 , characterising the Mediterranean mountains and semi-arid environments. A good correlation was found between the daily bedload flow and the liquid flow, the obtained model Qs = aQ b , can be easily used to estimate the bedload transport at the Hacine hydrometric station, located at the output and without data concerning this phenomenon.

“…Soil erosion due to water and wind results in the loss of valuable top soil and causes land degradation as well as environmental quality, water management and hydro-technical problems [BANASIK et al 2012;BANASIK, MITCHELL 2008;BĄK, DĄBKOWSKI 2013;BHATTARAI et al 2011;BOUCHELKIA et al 2014;KOWALCZYK, TWARDY 2012;MIODUSZEWSKI 2012;MITCHELL et al 2001]. There are different methods for soil conservation but biological methods in bare or degraded slopes need long time for establishment [ADEKALU et al 2007;CERDÀ 1999;SMETS et al 2008a;SPALEVIC et al 2014].…”

Mulches have extraordinary potential in reducing surface runoff, increasing infiltration of water into the soil and decreasing soil erosion. The straw mulches as a biological material, has the ability to be a significant physical barrier against the impact of raindrops and reduce the detachment of soil aggregates. The present study is an attempt to determine the efficiency of straw mulch as conservation treatment in changes in the splash erosion, time-to-runoff, runoff coefficient, infiltration coefficient, time-to-drainage, drainage coefficient, sediment concentration and soil loss. The laboratory experiments have been conducted for sandy-loam soil taken from deforested area, about 15 km of Warsaw west, Poland under lab conditions with simulated rainfall intensities of 60 and 120 mmh–1, in 4 soil moistures of 12, 25, 33 and 40% and the slope of 9%. Compared with bare treatments, results of straw mulch application showed the significant conservation effects on splash erosion, runoff coefficient, sediment concentration and soil loss and significant enhancement effects on infiltration and drainage. The results of Spearman-Rho correlation showed the significant (p < 0.05) correlation with r = –0.873, 0.873, 0.878 and 0.764 between rainfall intensity and drainage coefficient, downstream splash, sediment concentration and soil loss and with r = –0.976, 0.927 and –0.927 between initial soil moisture content and time-to-runoff, runoff coefficient and infiltration coefficient, respectively.

“…In the Maghreb countries, siltation and solid transport represent a major concern as they cause a lot of damage, such as the degradation of agricultural soils and water quality, which induce large financial losses for these countries [MEDDI et al 1998]. Numerous researchers have worked on the quantification of sediments transported in rivers and streams as well as on the relationships existing between hydro-meteorological drivers in Maghreb environments [ACHITE, OUILLON 2007;BOUCHELKIA et al 2014;BOUANANI 2004;BOUROUBA 1996;1998;BOUZERIA et al 2017;CHERIF et al 2009;DEMMAK 1982;EL MAHI et al 2012;GHENIM et al 2007;GHENIM, MEGNOUNIF 2013;MEDDI 1992;MEDDI et al 1998;SELMI, KHANCHOUL 2016;TIXERONT 1960;YLES, BOUANANI 2012]. In 114 dams currently operated throughout the Algerian territory, about 32 mln m 3 of water are lost annually as a result of siltation [MEKERTA et al 2008].…”

Soil loss is a major problem for watersheds management in semi-arid environments. The objective of the present study is to analyze the annual and seasonal patterns of suspended loads and quantify the specific sediment yields in a semi-arid environment of the Mazafran Watershed in central Algeria. The obtained information of water discharge and suspended sediment load, recorded during 19 years, was confronted with precipitation data in order to establish the relationships between the forcing agents and erosive processes. The specific sediment yield was estimated by assessing rating curve data under two types of identified responses. The obtained results allowed confirming the seasonality on suspended sediment transport in the studied basin, which accounts for 56% of the total suspended sediment load estimated in winter. The mean annual suspended sediment is estimated at 17.52 Mg•ha -1 •y -1 . The results highlighted that the type 2 event dominates the production of sediment in the study area in comparison with type 1 event. The analysis of the variability of rainfall erosivity index showed that there is a strong correlation between the annual precipitation and modified Fournier index (MFI), and a weak correlation with the monthly precipitation concentration index (PCI). Moreover, the spatial distribution of the modified Fournier index at the basin scale showed the highest precipitation aggressiveness in the Southern part of the study region for both type of events, whereas the precipitation aggressiveness low to moderate in the remaining part of the study region.
