“…This facies is truncated by a carbonate sequence and aeolian oolitic deposits. The uppermost continental Pleistocene is represented by continental red deposits and a centimeterto meter-thick calcrete extending over large areas (Ben Hamouda et al, 2011;Chakroun et al, 2005;Elmejdoub and Jedoui, 2009). At Taffeloun, the calcrete outcrops and its thickness is 15m (in clear blue in Fig 1b).…”

“…The Hammamet-Nabeul basin, which belongs to the Cap Bon peninsula at the north-eastern part of Tunisia, is located in the western coast of the Sicilian Strait (Elmejdoub and Jedoui 2009). It covers a total area of about 450 km 2 and it is limited in the north by the Grombalia basin, in the east by the oriental coastal plain, the south by the Gulf of Hammamet, and in the west by the Bouficha basin (Fig.…”

The scarcity of surface water in the HammametNabeul regional basin has imposed an over-abstraction of groundwater resources to meet the population demand for touristic and agricultural sectors. The impact of such a groundwater management on the aquifer system hydrodynamics and water quality has been investigated using a set of hydrochemical and isotopic data. Furthermore, a better understanding of the mineralization processes, the groundwater origins and the sources of recharge have been provided. Four water types were recognized; Na-HCO 3 , Ca-HCO 3 , Ca-SO 4 -Cl and Na-Cl. They are in relation with water-rock interaction processes i.e. the dissolution of evaporates and the cation exchange. Stable isotopes of water molecule ( 18 O and d 2 H) permit to identify three different groups. The first is characterized by relatively enriched isotope contents lending support to the important infiltration of recent rainwater in the foot of mountains. The second is distinguished by relatively depleted contents of stable isotopes reflecting a paleoclimatic origin. The third is marked by a significant enrichment of deuterium, which suggests a significant exchange with H 2 S in relation with the bacterial reduction of sulfate.

“…These organic matter-rich soils show cracking during the dry season and are generally suitable for horticultural and orchard cultivation. Some other parts of the study area are marked by the abundance of Mediterranean red soils, which have fine texture and a well-developed polyhedral structure and calcareous accumulations (Elmejdoub and Jedoui 2009). The landscapes and topography, as well as the habitats and biota, all contribute towards the richness and diversity of floral cover in the study area.…”

Detailed hydrogeochemical and isotopic data of groundwaters from the Hammamet-Nabeul unconfined aquifer are used to provide a better understanding of the natural and anthropogenic processes that control the groundwater mineralization as well as the sources of different groundwater bodies. It has been demonstrated that groundwaters, which show Na-Cl and Ca-SO 4 -Cl water facies, are mainly influenced by the dissolution of evaporates, the dedolomitization and the cation-exchange process; and supplementary by anthropogenic process in relation with return flow of irrigation waters. The isotopic signatures permit to classify the studied groundwaters into two different groups. Non-evaporated groundwaters that are characterized by depleted d 18 O and d 2 H contents highlighting the importance of modern recharge at higher altitude. Evaporated groundwaters with enriched contents reflecting the significance infiltration of return flow irrigation waters. Tritium data in the studied groundwaters lend support to the existence of pre-1950 and post-1960 recharge. Carbon-14 activities in shallow wells that provide evidence to the large contamination by organic 14 C corroborate the recent origin of the groundwaters in the study area.
