“…The resistivity from field measurement is referred to as the apparent resistivity, this is based on the assumption that the homogeneous subsurface (Telford et al, 1990). The Wenner -Schlumberger array is a better resolution for horizontal structure (Loke et al, 2010) and is appropriate to investigate saltwater distribution (Kazakis et al, 2016).…”

“…Neogene, Pleistocene, and Holocene sediments host the porous aquifer that consists mainly of gravel, sand, and marls. A detailed description of the aquifer can be found in relevant studies [1,41]. The aquifer is found in both confined and unconfined conditions, while negative piezometric head reaches up to 40 m below sea level (b.s.l.)…”

“…Groundwater depletion due to overexploitation is the main cause of coastal aquifer salinization in Greece [1]. Two main salinization processes occur in depleted aquifers: (a) seawater intrusion [1] and (b) salt water upconing [2]. Mapping the vulnerability of coastal aquifers to seawater intrusion [3] and salt water upconing [4] has been proposed as a tool with which to prevent groundwater salinization.…”

Abstract:Coastal aquifer salinization is usually related to groundwater overexploitation and water table decline. Managed Aquifer Recharge (MAR) can be applied as a measure to reverse and prevent this phenomenon. A detailed literature review was performed to identify the various methods and parameters commonly used to determine suitable sites of MAR application. Based on the review results, a new multi-criteria index (SuSAM) that is compatible to coastal aquifers was developed to delineate suitable zones for MAR application. New parameters were introduced into the index, such as distance from the shore and hydraulic resistance of the vadose zone, while factor weights were determined using the Analytical Hierarchy Process (AHP) and single sensitivity analysis. The applicability of the new index was examined in the coastal aquifer of the Anthemountas basin located in northern Greece. The most suitable areas for MAR application cover 28% of the aquifer's surface area, while 16% of the area was characterized as non-suitable for MAR application. The new method constitutes the first step of the managed aquifer recharge concept for the delineation of MAR-suitable zones in coastal aquifers.

“…In Europe, seawater intrusion affects almost all Mediterranean coastal aquifers to some degree, particularly those in Spain (Guhl et al 2006;García-Menédez et al 2016), Italy (Barrocu 2003;Benini et al 2016), Greece (Petalas and Lambrakis 2006;Kazakis et al 2016), and Turkey (Günay 1997;Arslan et al 2012). Coastal aquifers also show signs of seawater intrusion in countries such as Poland and Finland (EEA 2007).…”

A large number of coastal aquifers worldwide are impacted by seawater intrusion. A major aim of European Directives 2000/60/EC and 2006/118/EC is to achieve good ecological status in groundwater bodies, including coastal aquifers. To this goal, information is needed about the current state of, and changes over time in, individual aquifers. This information can be obtained by applying methods that determine the status of aquifers in an uncomplicated manner. Methods for this type of assessment must comply with three essential criteria. First, calculation of the index must be straightforward and should be based on easy-to-obtain or commonly available data. Next, the index should be able to highlight important characteristics in understandable terms. Finally, the results should be objective and should be expressed in such a way that different time periods and different aquifers can be compared. In this paper we describe the development of a method to characterize seawater intrusion that meets these criteria and is based on four basic parameters: surface area, intensity, temporality, and evolution. Each parameter is determined by specific calculations derived from the groundwater chloride concentrations. Results are specified as a numerical index and an alphanumeric code. This index, known as SITE, has been applied to four Mediterranean coastal aquifers. The standardized results allowed us to discriminate between, and objectively compare the status of these groundwater bodies. Further, this index will make it possible to prioritize management actions and evaluate the effectiveness of these actions over time.
