Global threat of arsenic in groundwater
Science, 2020 Dowsing for danger Arsenic is a metabolic poison that is present in minute quantities in most rock materials and, under certain natural conditions, can accumulate in aquifers and cause adverse health effects.

Asymmetric impact of groundwater use on groundwater droughts [PDF]
Hydrology and Earth System Sciences, 2020 Abstract. Groundwater use affects groundwater storage continuously, as the removal of water changes both short-term and long-term variation in groundwater level. This has implications for groundwater droughts, i.e. a below-normal groundwater level. The impact of groundwater use on groundwater droughts remains unknown. Hence, the aim of this study is to

Attention U-Net as a surrogate model for groundwater prediction [PDF]
Advances in Water Resources, Volume 163, May 2022, 104169, 2022 Numerical simulations of groundwater flow are used to analyze and predict the response of an aquifer system to its change in state by approximating the solution of the fundamental groundwater physical equations. The most used and classical methodologies, such as Finite Difference (FD) and Finite Element (FE) Methods, use iterative solvers which are ...

Groundwater flood or groundwater-induced flood? [PDF]
Quarterly Journal of Engineering Geology and Hydrogeology, 2012 A number of ‘groundwater flood’ events have been recorded over the Chalk aquifer in southern England since the 1994 occurrence at Chichester, Sussex. Reporting of this event and subsequent groundwater floods indicates that there are two types of groundwater flood event. Type 1 is the true groundwater flood in which the water table elevation rises above
