“…During the measurement of 2021, several drains had not functioned since 2018. Another explanation can be mentioned here but we cannot adopt it since it is out of the scope of this research, which is the non-homogeneity of the unconfined aquifer (phreatic aquifer) and its intercalation by clay lenses at a shallow depth that act as a substrate to support groundwater to rise [25]. Furthermore, the responsible purification plant for purifying the wastewater collected from the study area is suffering from different problems such as the breakdown of some pumps in different purification stages, especially in the Desander and this is mainly because of the high level of wastewater in the grit trap causes the two suction pumps to break down and the third insufficient, which creates considerable pressure on the plant and consequently reducing the required purified of the drained wastewater volumes.…”

“…Unfortunately, this project failed to combat its main objective due to several problems. However, Oued Souf was and still is an open book for various studies to understand the principal reasons for shallow groundwater upwelling and its forecasting trying to refer this phenomenon to the hydrogeological setting of the region or anthropogenic activities [22][23][24][25][26][27][28].…”

Since the beginning of the 1980s, several regions in the northern Sahara of Algeria have been confronting the rising groundwater. Among all these regions, Oued Souf Valley represented one of the most acute affected by this phenomenon. Due to the natural topography and the insufficient/weakness of water management and miscoordination between different sectors that are represented by intensive exploitation of deep groundwater reservoirs which returns to the shallow aquifer, absence of sewage and drainage network, leakage from drinking water supply system, the groundwater has raised to the surface or near to the surface, affecting the traditional cultural environment and urban areas and degrading all socio-economic aspects of the Oued Souf habitants. To preserve the Oued Souf environment, a vertical drainage system has been constructed. Consequently, in this research, an evaluation of the vertical drainage system performance and its impact on groundwater level stabilization has been performed by mapping the water table of the phreatic groundwater level using geostatistical modeling using ordinary kriging (OK) interpolation method, which has been applied to analyze the spatial and temporal structure of groundwater level fluctuation. Meanwhile, hierarchical cluster analysis (HCA) was applied for grouping the wells based on the groundwater fluctuations for 2008, 2009, 2014, 2016, 2018, and 2021. However, the vertical drainage system reflected a significant decline of groundwater from 2009 to 2018 due to the important drained volumes through it but another rising phenomenon might be threatening the region in the near future and this is what was indicated in the 2021 groundwater level data. Cluster analysis has generated four groups based on their fluctuation means that are increasing from the first group to the fourth group ascendingly. The first cluster grouped the drains that have a shallow depth (average mean of 5.91 mbgl) and declined over the clusters. The clusters are spatially combined with significant separation of the fourth cluster which represents the deepest group (12.89 mbgl). Based on this research, several factors are influencing the stability of the phreatic groundwater level and even the performance of the drainage system, the most important of which is the overexploitation from deep groundwater reservoirs such as complex terminal and continental intercalary (in drinking and irrigation) and even the illegal use of the phreatic groundwater with important quantities for irrigation and illegal industries.
