“…• The prolongation of the dry period during several months has destroyed the plant cover that characterizes as the main soil protector against the splash effect (Benkhadra 1997). • Only a part (20%) of the Macta watershed has forest cover, consisting mainly of Aleppo pine and holm oak, and hence provides a very weak protection against soil erosion (Hallouche et al 2017). • The elongated shape of the watershed and the irregularities in the rainfall and the vegetation cover are linked to the fragility of the soil…”

“…According to the morphometric data of the watershed, it is possible to distinguish the factors that favour erosion in the Mekerra region as well as the elongated shape of the watershed, irregular rainfall, and a weak vegetation cover (Benkhadra 1997, Hallouche et al 2017). The thermal regime may increase evapotranspiration, rapid soil drying, and degradation of vegetation cover.…”

In this study, we evaluate the soil erosion and solid transport in the oued Mekerra watershed in north-west Algeria. The study area is subject to a semi-arid climate characterized by irregular rainfall and showers, which are often accompanied by significant floods. These floods of large volumes transport large amounts of solid input to the Sarno dam, which is in the outlet of oued Mekerra. Therefore, the water storage capacity of this dam is gradually decreasing, and it might reach the volume of dead water. For this study, we utilized the hydrometric database provided by the National Agency of Water Resources (ANRH). The operating period was 24 years, from 1988 to 2012. This period was extended by classic regression to 65 years, which allowed extracting a series of annual maximum instantaneous flow rates (Q IXA ) and subsequently quantified the sediment yield during floods. The specific degradation mean created by the 11 floods was quite high, in the order of 20 t km 2 year −1 . The highest value of solid contribution was observed during the floods of October 2000 (250,000 t), and the value of liquid contribution was 7,151,608 m 3 . The extracted results from the analysis of the graphs of concentration as a function of the liquid flow (C = f′(Q l )) showed four types of hysteresis curves: clockwise loop, counterclockwise loop, shape of eight, and straight line curve. Class II (clockwise loop) was the dominant class in the four events, namely the floods that occurred on 09/22/1992, 09/21/1998, 09/27/1999, and the 08/24/2002. From these results, the water resource sector managers could formulate various methods for protection from floods and against the risk of sedimentation in storage structures.

“…Confusion may arise when works assess the importance of water-rock interaction and/or evaporation on groundwater quality based on the location of samples on Gibbs diagram (Adimalla and Venkatayogi, 2017;Barzegar et al, 2017;Chintalapudi et al, 2017;Hallouche et al, 2017;Haritash et al, 2017;Ibrahim Hussein et al, 2017;Latifa et al, 2017;Mahmoudi et al, 2017;Raj and Shaji, 2017;Singh et al, 2017). Some even suggest that Gibbs (1970) assessed the evolution of groundwater rather than surface water quality (Chintalapudi et al, 2017) (Song et al, 2017).…”

The 'Gibbs Diagram' represents some of the key processes controlling surface water chemistry. This review highlights that the processes listed on the Gibbs Diagram may not be applicable for assessing processes controlling groundwater chemistry. We discuss the importance of geochemical processes governing groundwater chemistry in the Gibbs Diagram framework. We show that the processes represented on the Gibbs Diagram-originally developed for surface waters-unlikely represent key processes controlling the chemistry of most groundwater systems. Highlights• We explain the background of Gibbs (1970) diagram • We show the limitations of the use of Gibbs diagram in case of groundwater systems • We discuss the main processes defining the groundwater geochemistry

“…Over-dependence on the groundwater resources and human interventions in the catchments has often led to large-scale decline in the quantity and quality of the groundwater resources even in mountainous catchments (Guo and Wang, 2005;Peisert and Sternfeld, 2005;Vaux, 2007;Sadoff and Muller, 2009;Padmalal et al,2011;Vaux, 2011;Hallouche et al, 2017;Kaushal et al,2017). Social and economic activities of the catchments are mostly dependent on the availability and quality of groundwater for various purposes (Hosseinifard and Aminiyan, 2015;Elgallal et al, 2016;Chandran et al, 2017;Wu et al, 2017;Jampani et al, 2018 andPincetti-Zúniga et al,2020).…”

Spatiotemporal variability in groundwater chemistry of a mountainous catchment with complex geologic and climate gradients in south west India

Mountainous catchments are one of the world's important water sources that sustains a major portion of global population and a rich biodiversity. The groundwater quantity and quality of mountainous watersheds are depended generally on the geologic characteristics and climate gradients. Although many groundwater studies have been carried out in the midlands and lowlands of many river basins, not enough focus has been paid to the mountainous catchments of tropics. Here we report a case study on groundwater quality and controlling factors of a mountainous catchments of the Western Ghats mountain ranges of peninsular India -the Bhavani river basin, which is identi ed as a testbed for longterm monitoring of the Critical Zone process. A total of 88 water samples were collected seasonally for assessing various physico-chemical parameters, solute contents and scaling properties. The results of the study revealed that the hydrochemistry of groundwater is in uenced by both silicate and carbonate weathering. Mineral stability indices computed for the groundwater reveal that about 52 % of the samples are supersaturated with carbonate minerals and often exhibit scaling due to solute overloading. Among the contributing factors that determine water quality of groundwaters, chemical weathering and anthropogenic activities play a signi cant role.
