“…So, these characteristics have an influence on the soils and their behavior in the studied area where: -the high precipitations with the absence of vegetal coverage and the low soil permeability (clays), leads to superficial flows; the later favor a high drainage density and the transport of the extracted particles to Mila River causing the contamination and siltation of BeniHaroun dam (Kateb et al, 2020;Habila et al, 2010); -the steep slope in areas with groundwater flows within and between clay layers, constitutes a trigger factor of landslides and favor the particles pulling, which generating differential settlements; also, the particles are gradually evacuated by flow, in the slope direction (S-N); this phenomenon destabilizes the soil structure and increases the hydraulic gradient locally; if this gradient still increases slightly, the soil lifts; this dangerous phenomenon is related to the speed of water flow; in our case, the provoked hydraulic gradient under material's nature and hydraulic load, can lead to the infiltration which due to permeability coefficient and infiltration resistance by downward vertical flow; so, it causes cracking and damage to buildings in the studied area (Brencich & Gnecco, 2012;Chettah, 2009;Khellaf, 2019;Hazmoune, 2008); -the presence of the aquifer in gypsum clay, with limestone blocks and their flows, promote the dissolution of this gypsum which increases the soil aggressiveness for concrete (Khellaf, 2019;Khellaf et al, 2018); furthermore the several landslide seats in our region where the potential of instability risk increases during the winter period (Zouaoui, 2008); -the presence of groundwater, generally, leads shear resistance reduction (Chen et al, 2019), mechanical characteristic of soils (friction angle (φ), cohesion (C)), and progressive increase deformability under load (Zouaoui, 2008) that influences the bearing soil's capacity (Khellaf, 2019); -the groundwater fluctuations causing an enormous hydrostatic pressure, recharging/folding, affects the soil volume variation (shrinking-swelling), then the calculation and the proper structural foundations functioning (Khellaf, 2019).…”

Feasibility study for the southern extension of Mila town (northeast of Algeria) for urbanization purposes: a geotechnical and hydrogeophysical approach

The population of Mila is increasing and local authorities are looking for new lands to develop the town and provide housing. However, the soil of these lands is unstable and requires detailed studies to serve as a foundation. This work presents the geotechnical and the geophysical characteristics of the Marechau soils, which forms the southeast extension of the Mila town. To provide an idea about the soil condition, to choose the type of adequate constructions and to make decision for building it, we adopted a geotechnical approach, where we analysed the soils by carrying out core drilling tests, dynamic penetration tests and the laboratory tests. We also, employed the geophysical approach in determining the electrical resistivity so as to map the depth of bedrock roof. Furthermore, we conducted a comprehensive hydrogeological study, monitoring precipitation and the piezometric level of the aquifer over a period of 200 days, and determined the flow direction. The core drilling test results indicate a clayey soil with limestone blocks. The dynamic penetration test show two categories of soil. The laboratory tests show that the materials analysed are very plastic, over-consolidated and medium to very compressible. They have a medium to high swelling potential and medium amount of aggressiveness to concrete. Besides, the tomography results also showed a single layer land (clay) with massive rocks embedded in it. The piezometric monitoring reveals the presence of two aquifer systems. The first is superficial and the second is deep. They don’t recharge directly after the rain falls and the groundwater flows in the direction of the slope. All the results indicate that solutions must be found for soil movements in the area under study before urbanization takes place. The combination of these results with the location, land morphology, tectonic activity, and seismotectonic aspects suggest that the area presents a high risk, and its urbanization requires rigorous and mandatory precautionary measures.

“…The five meteorological stations are distributed from northwest to southeast and almost cover the entire watershed, which meet the requirements of the model for meteorological input data (Yang et al, 2019a(Yang et al, , 2019bZhou & Li, 2015). Thus, the calculated meteorological data are used to build weather database and weather generator in SWAT (Kateb et al, 2020). The National Earth System Science Data Sharing Infrastructure provided the monthly streamflow data at the Ganguyi station, which are used to calibrate the model.…”

Evaluation of the impact of the Gully Land Consolidation Project on runoff under extreme rainfall

et al. 2022

Extreme rainfall is an important driver of soil erosion and land damage. The Gully Land Consolidation program (GLCP) was first launched in 2011 as a major land reclamation practice to increase farmland in the Loess Plateau of China. Studying the impact of artificial projects on hydrology can help humans to respond to the various water issues, but the assessment of the effects of the GLCP on extreme rainfallinduced water runoff at watershed scale is currently lacking. Our study used the soil and water assessment tool (SWAT) to evaluate the influence of the GLCP at different locations and areas on water runoff under extreme rainfall events in the Yanhe watershed. Results showed that: (1) the GLCP can improve the interception of surface runoff, with interception efficiency in downstream of the watershed approximately twice that at midstream and entire watershed as well as seven-times that at the upstream; (2) when GLCP measures are evenly distributed in a watershed, as the area of GLCP increases from 76.40 km 2 (1% of watershed area) to 382.01 km 2 (5%), the interception of surface runoff increases by 0.77 mm; (3) and the GLCP can increase soil infiltration and groundwater recharge. This research is expected to provide insights into the optimized layout of the GLCP at watershed scale. Correspondingly, policymakers can refer to this information in developing policies on the sustainable use of land.

“…Based on FAO-ISRIC (Food and Agriculture Organization of the United Nations International Soil Reference and Information Centre), the database DSMW (Digital Soil Map of the World) is imported into Arcgis10.4 in order to extract the four soil characteristics and generate the soil erodibility map. In order to determine the soil erodibility, the formula of Williams (1995) is adopted that has been widely used by several researchers (Chikh et al, 2019;Kateb et al, 2020). The used equation for K determination is as follows:…”

Soil erosion is one of the problems threatening the Algerian environment. In agriculture, soil erosion leads to the thinning of the topsoil under the effect of the natural erosive forces of water, or under the effect of agricultural activities. The present study aims to estimate average soil loss rate and to identify vulnerable zones. Through the integration of RUSLE model at the Saf Saf watershed, various parameters are utilized such as the rainfall erosivity factor (R), soil erodibility factor (K), slope length - slope factor (LS), crop management factor (C) and practice management factor (P). All these parameters are prepared and processed through a geographic information system (GIS) and remote sensing using various database sources. The results reveal that the river basin has an average annual soil loss of 3.9 t ha−1 yr−1, and annual soil loss of 4.53 million tonnes for the period 1975-2017. Meanwhile, eighty five percent of the study area is experiencing acceptable rate of soil erosion loss, which is ranging between 0 to 5 t ha−1 yr−1. The present study of risk assessment can contribute to understand the spatial pattern of soil erosion in order to use appropriate conservation practices for sustainable soil management.
