ion of multivariate statistical analysis as a support for the delineation of groundwater bodies: a case study in coastal plain areas of Campania Region (Southern Italy)

The identification of hydrogeological boundaries and the assessment of groundwater’s quantitative and qualitative status are necessary for delineating groundwater bodies, according to the European Guidelines. In this context, this study tries to verify the current delineation of groundwater bodies (GWBs) through hydrogeochemical methods and multicriteria statistical analyses.

Showcasing a global-scale, 3D coastal groundwater salinity model

Being extensively available and of high quality, groundwater is the primary source of freshwater in coastal regions globally. However, due to anthropogenic and natural drivers, groundwater salinisation is a growing threat to this resource’s long- and short-term viability. The causes and timescales of aquifer salinisation are complex and difficult to quantify, information essential for suitably timed mitigation strategies. One way to inform these strategies and develop storylines of future freshwater (un)availability is through 3D groundwater salinity modelling.

Groundwater/Wetland Interactions In A Coastal Aquifer In The Eastern Cape Province Of South Africa.

This study, near Thyspunt between St. Francis and Oyster Bay in the Eastern Cape Province of South Africa, focused on identification and quantification of surface water–groundwater links between the mobile Oyster Bay dune field and the coast. The specific objective was to establish the extent to which important wetlands such as the Langefonteinvlei and the numerous coastal seeps along the coast are directly or indirectly dependent on groundwater as their main water source.

Characterisation Of Hydrochemical Facies And Water Quality Of The Coastal Plain-Sand Aquifers Of Parts Of Eastern Niger Delta, Nigeria

Soil and water pollution are major environmental problem facing many coastal regions of the world due to high population, urbanisation and industrialisation. The hydrofacies and water quality of the coastal plain-sand of part of Eastern Niger-Delta, Nigeria, was investigated in this study.

Effects of Tidal Variation on LNAPL distribution in an aquifer

Collecting groundwater information close to the ocean often raises the question whether a tidal effect could be influencing the data. Sometimes this issue leads to speculation that is counterproductive and sometimes it is overlooked thereby causing judgement errors when interpreting data. This paper looks at the theoretical background of tidal influences in coastal aquifers to identify the screening factors to consider when deciding whether a contaminated site assessment needs to take tidal influences into account.

Multivariate Statistical Analysis Of Hydrochemical And Environmental Isotope Data To Characterise The Hydrogeological And Hydrogeochemical System Of The Lake Sibayi Catchment, North-Eastern South Africa

An integrated approach involving multivariate statistical analysis combined with graphical methods (Piper trilinear diagram and δ18O-δ 2H plots), and environmental isotope analyses were successfully applied to characterise the spatial distribution of hydrogeochemical parameters and their controlling factors within the Lake Sibayi catchment located in north-eastern South Africa.
