Hanoi city has abundant groundwater, supplemented by the surface water (mainly Red River) all year round, and extensive shallow aquifers, which are easily exploited large-diameter wells. There always exists some open hydrogeological windows in River area with an structure; therefore, groundwater a strained hydraulic relationship system Along from Ba Vi to end of Phu Xuyen district, there nine r...

Abstract. The mechanism of radial dispersion is essential for understanding reactive transport in the subsurface and estimating aquifer parameters required optimization design remediation strategies. Many previous studies demonstrated that injected solute firstly experienced a mixing process injection wellbore, then entered skin zone after leaving finally moved into through advective, diffusive...

[1] Submarine groundwater discharge (SGD) into the ocean is increasingly recognized as an important component of land-ocean interaction. Numerous geological settings may be the source of terrestrially derived SGD, including spatially extensive sand dune systems, which are a common coastal setting in tropical, subtropical, and temperate regions throughout the world. Within the catchment of the G...

Geogenic arsenic (As) contamination of groundwater is a health threat to millions people worldwide, particularly in alluvial regions South and Southeast Asia. Mitigation measures are often hindered by high heterogeneities As concentrations, the cause(s) which elusive. Here we used comprehensive suite stable isotope analyses hydrogeochemical parameters shed light on mechanisms typical high-As Ho...

Abstract. Frozen layers within the subsurface of rock glaciers are generally assumed to act as aquicludes or aquitards. So far, this behavior has been mainly defined by analyzing geochemical characteristics spring waters. In work, for first time, we experimentally confirmed assumption executing an infiltration test in a glacier Southern Alps, Italy. Time-lapse electrical resistivity tomography ...

Nearly 40 years ago, Neuman (1968) developed an analytical solution for drawdown in a system of three aquifers separated by two aquitards when one of the aquifers is pumped at a constant rate. Whereas the simpler case of two aquifers separated by one aquitard has been presented by Neuman and Witherspoon (1969a), the full five-layer solution has not been previously evaluated. We do so here using...
