Recharge and paleo-recharge of groundwater in different basins in Tunisia
2020, Quaternary InternationalSedimentary and microfaunal evolution in the Quaternary deposits in El Akarit river mouth (Gulf of Gabes, Tunisia): Paleo-environments and extreme events
2016, Journal of African Earth SciencesCitation Excerpt :Both marine and fluvial influence is observed in phase 3, which can be attributed to the sediment transport during floods, which might be concomitant to the storms. Before 3000 yr cal BP, the subaerial paleoenvironment is submitted to the strong erosive action of the wadi Akarit during normal weather conditions, with enhanced erosion activity during major floods (Fontes et al., 1983; Zouari, 1988). The above described “extreme events” cannot be directly related to chronologically well-defined phases of climate deterioration in the south Mediterranean areas, because of the discontinuous features of the studied sediment series AK1.
Hydrogeochemical and stable isotope data of groundwater of a multi-aquifer system: Northern Gafsa basin - Central Tunisia
2016, Journal of African Earth SciencesCitation Excerpt :These values of local precipitation are much higher than those supposed to be for the LC and UC groundwaters, indicating either a recharge altitude effect and/or a palaeoclimatic impact: recharge under humid and colder climatic conditions than at present day. This hypothesis of ancient recharge agrees with the results of Fontes et al. (1983), Ouda (2000), Yermani et al. (2002); Zouari et al. (2003) and Hamed et al. (2008 and 2010a,b) obtained in south Tunisia, which were interpreted as recharge occurring during the Late Pleistocene and the Early Holocene periods. This period Pleistocene and Holocene that could be responsible for the periodic recharge of old groundwaters in the North Africa.
Use of geochemical, isotopic, and age tracer data to develop models of groundwater flow: A case study of Gafsa mining basin-Southern Tunisia
2014, Journal of African Earth SciencesCitation Excerpt :Moreover, the fact that the CT groundwater lies well below the meteoric water lines also indicates that the evolution of air masses was different to the present-day with little or no primary evaporation and probably little upcoming from its Atlantic Ocean source region which was isotopically enriched as a result of ice-cap formation (Andreoa et al., 2004). On the other hand, the stable isotope results are also consistent with the those of carbon-14 (ERESS, 1972; Gonfiantini et al., 1974; Fontes et al., 1983; Mamou, 1990; Daoud, 1995; Guendouz and Moulla, 1996; Guendouz et al., 1997; Zouari and Mamou, 1997; Jedoui et al., 2001; Yermani et al., 2002; OSS, 2003; Edmunds et al., 2003; Zouari et al., 2005; Kamel et al., 2006; Hamed et al., 2008, 2012b; Hamed, 2009; Mokadem et al., 2012), which indicate that the main recharge of the C.T in Southern Tunisia and Algeria occurred during the Late Pleistocene and the Early Holocene periods. In North Africa, three major humid phases have been identified: (1) the Early Würm pluvial (MIS 3) “70–40 ka before present”, (2) the Middle Würm pluvial (MIS 3) “32 to about 22 ka before present” and (3) the Late Würm pluvial (MIS 2) “18–11 ka before present” (Zuppi and Sacchi, 2004).
The use of hydrochemical and environmental isotopic tracers to understand the functioning of the aquifer system in the Bou Hafna and Haffouz regions, Central Tunisia
2014, Quaternary InternationalCitation Excerpt :The first group includes groundwater samples distinguished by relatively high 14C activities, suggesting their recent origin related to the recharge by present day rainfall in the foot of the bordering highland. The second group is composed of groundwater samples characterized by relatively depleted 14C activities, indicating their palaeoclimatic origin in relation with recharge during the humid period of the Holocene and the Late Pleistocene (Fontes et al., 1983; Mamou, 1990; Ouda, 2000; Edmunds et al., 2003; Zouari et al., 2003; Jéribi, 2004; Dassi et al., 2005; Kamel et al., 2005; Kamel, 2007; Hamed et al., 2008). Groundwater hydrodynamic and mechanisms of mineralisation of Haffouz and Bou Hafna aquifers have been investigated using conventional hydrogeological field investigations, major ions, and isotope hydrology data.
