In this paper, the effect of tidally influenced water elevations on the concentration of groundwater contaminants discharging to a surface-water body is studied using a one-dimensional homogeneous sand column.Abstract:
An investigation of the effect of tidally influenced water elevations on the concentration of groundwater contaminants discharging to a surface-water body is studied using a one-dimensional homogeneous sand column. A constant water level is imposed upstream, and the downstream water level is controlled by a wave generator that controls the hydraulic head to mimic a 12-h tidal fluctuation. The experimental results demonstrate that the tidal fluctuations in the downstream reservoir result in a decrease in average contaminant concentration at the point of discharge to the tidally influenced surface-water body. The further upstream an observation well is located, the smaller the amplitude of the concentration oscillation. Fourier analysis suggests that the dominant frequency of the pressure at different locations along the length of the column is identically two cycles per day and that the concentration data have a dominant frequency of two cycles per day, but also exhibit harmonics.read more

Numerical assessments of recharge-dominated groundwater flow and transport in the nearshore reclamation area in western Taiwan
TL;DR: The results suggest that a land drainage system near the site can play an important role in contaminant transport in the reclamation area and that the key factor in controlling plume migration is the recharge rate.

The subterranean estuary: a reaction zone of ground water and sea water
TL;DR: The importance of underground estuaries in coastal aquifers has been emphasized by the use of chemical tracers in the coastal ocean as mentioned in this paper, which can be used to evaluate the importance of these unseen estuars in supplying not only chemical tracer, but also nutrients, to coastal waters.

Effect of tidal forcing on a subterranean estuary
TL;DR: In this article, a numerical study of the dynamics in a subterranean estuary subject to tidal forcing is presented, showing that salt transport associated with tidally driven seawater recirculation leads to the formation of an upper saline plume in the intertidal region.
