Abstract Laboratory scale experiments and numerical modelling were employed in this study to investigate saltwater intrusion fractured aquifers. Saline was initiated one homogeneous six experimental aquifers containing individual discontinuities of varying length orientation. Automated image processing enabled high precision quantification three variables, the toe saline wedge, width mixing zon...

25 A numerical study, based on a density-dependent variably saturated groundwater flow model, 26 was conducted to investigate flow and salt transport in a near-shore aquifer under intensified 27 wave conditions caused by offshore storms. Temporally varying onshore hydraulic gradients due 28 to wave set-up were determined as the seaward boundary condition for the simulated aquifer. 29 The result...

Performance of freshwater aquifer storage and recovery (ASR) systems in brackish or saline aquifers is negatively affected by lateral flow, density effects, and/or dispersive mixing, causing ambient groundwater to enter ASR wells during recovery. Two recently published ASR performance estimation methods are applied in a Dutch coastal area, characterized by brackish-to-saline groundwater and loc...

The majority of this course has focused on large scale climate and human health applications. The paper presented here, however, is an example of a smaller scale application of statistics to a geo-environmental issue. Researchers intend to model groundwater in an approximately 200 kilometer (km) by 300 km area around the city of Winnipeg, Manitoba, Canada. The study area is located on the easte...

In the coastal multilayer aquifer system of a highly urbanized southern city (Recife, Brazil), where groundwaters are affected by salinization, a multi-isotope approach (Sr, B, O, H) was used to investigate the sources and processes of salinization. The high diversity of the geological bodies, built since the Atlantic opening during the Cretaceous, highly constrains the heterogeneity of the gro...

A multidisciplinary study involving hydrogeochemical sampling and borehole geophysics was undertaken to study the nature and occurrence of saline groundwater on two islands in British Columbia, Canada. Saturna and Hornby Islands are located at the south and north ends, respectively, of the Canadian Gulf Islands situated off the lower mainland of British Columbia. Two large-scale geochemical sam...

In modeling geologic carbon sequestration in a deep inclined aquifer in Wyoming, the impact of geologic, engineering, and environmental uncertainty factors on parameter importance and prediction uncertainty is evaluated. Given site characterization data, a suite of geologic model families were built to represent aquifer permeability heterogeneity at increasing complexity. With each family, the ...

CO2 Storage in Saline Aquifers — Saline aquifers represent a promising way for CO2 sequestration. Storage capacities of saline aquifers are very important around the world. The Sleipner site in the North Sea is currently the single case world-wide of CO2 storage in a saline aquifer. A general review is given on the specific risks for CO2 storage in saline aquifer. The regional distribution of C...

q-mode hierarchical cluster (hca) and principal component analysis (pca) were simultaneously applied to groundwater hydrochemical data from the three times in 2004: june, september, and december, along the ain azel aquifer, algeria, to extract principal factors corresponding to the different sources of variation in the hydrochemistry, with the objective of defining the main controls on the h...
