Opis:
The aim of this paper is to assess the groundwater potentiality using statistical multi-criteria evaluation and AHP (analytic hierarchy process) as an additional method to the hydrogeological research in order to create a map that represents the groundwater potentiality. The extraction of this map is based on the study of multi-criteria input data, such as lineaments, land use, lithology, drainage, slope, soil, rainfall and geomorphology. Weights were assigned using the AHP method to all these multi-influencing factors according to their influence on groundwater potential. Sensitivity analysis was calculated to validate the AHP weights result. The presented methodology has been applied to the Bouhedma region in southwestern Tunisia, located in an arid climate. This technique revealed that very good, good, moderate and poor groundwater potential zones are spread over 382 km2 (26.9%), 437 km2 (30.7%), 552 km2 (38.8%) and 51 km2 (3.6%), respectively. Furthermore, the effect of each influencing factor on groundwater capacity was computed. The results provide significant information and found to be helpful in better planning and management of groundwater resources.

Opis:
The N–E Tunisian coast (Bizerte region) shows several Quaternary sedimentary archives of middle to late Pleistocene age. Sedimentological analyses carried out (grain size, morphoscopy, exoscopy, petrography, mineralogy, and fossil content) on 12 sections reveal a succession that begins with infratidal deposits attributed to the last Interglacial period, followed by intertidal, continental (palaeosol) and/or aeolian deposits (aeolianites). The arrangement of these deposits, their lithological characteristics and their faunal contents are the basis for a palaeoenvironment reconstruction and estimation of palaeoclimatic conditions. A warmer climate and a high sea level characterize the beginning of this interval, followed by a sea level fall accompanied by an alternation of humid and arid climate. This alternation is reflected by intercalations of the palaeosol levels between the aeolian deposits.

Opis:
This study is based on the analysis of the sedimentology and the fossil assemblages of the Pleistocene deposits in Eastern Tunisia. It aims to establish the different fauna assemblages in order to highlight their paleoenvironments and discuss the importance of the Persististrombus latus distribution especially in the MIS 5e deposits around the Mediterranean Basin. The stratigraphic succession has been divided into two main units. The lower unit is quartz-rich sediment. Its lower marine term revealed well preserved species (Bivalves, Gastropods, Echinoids and Scirripedia) dominated by Acanthocardia, Cerastoderma, Parvicardium, Arca, Donax, Glycymeris, Loripes, Tellina and Cerithium. This fauna is representative of a typical association/biocenosis which may be developed in a sheltered bay, where the hydrodynamism is regularly moderate to low and/or quickly post-mortem buried. The upper unit is carbonated. Its basal term is also rich marine fauna which contains the extant tropical West African species Persististrombus latus. The occurrence of Persististrombus latus in this unit compared to its presence in the whole Mediterranean basin in the Late Pleistocene leads to question its importance in the interpretation of the climate warming during the Late Pleistocene, and to suggest its Atlantic origin.
