“…Ray et al (2002) adopt such an approach to demonstrate the risk of contamination from surface water at a site on the River Illinois for different combinations of transport parameters. The model results interpreted with pesticide monitoring data showed that even during a flood, the risk of contamination from nitrate and atrazine is low for a small capacity (2.7 £ 10 3 m 3 day…”

Bank filtration, either natural or induced through the river bed by pumping from a system of connected lateral or vertical wells, provides a means of obtaining public water supplies. The success of such schemes is dependent on the microbial activity and chemical transformations that are commonly enhanced in the colmation layer within the river bed compared to those that take place in surface or ground waters. The actual biogeochemical interactions that sustain the quality of the pumped bank filtrate depend on numerous factors including aquifer mineralogy, shape of the aquifer, oxygen and nitrate concentrations in the surface water, types of organic matter in the surface and ground water environments, and land use in the local catchment area. This paper provides an introduction to a series of nine papers contained in this Special Issue that highlight these factors and finishes with a list of recommendations for co-ordinated research into attenuation of groundwater pollution by bank filtration. q

“…The influence of the Allier River in the drinking water wells cannot easily be related to flow in the alluvial deposits as the hydraulic gradients preclude it. The most credible hypothesis is that there is bank infiltration of river water as claimed by Ray et al (2002) and Schubert (2002). The results also indicate a large influence of alluvial aquifer s.s. water (50 to 80%), whereas that of slope water is very low in wells 1 and 4 (0 to 5%) and much higher in wells 2 and 3 (20 to 30%).…”

“…The hydrology and water quality of rivers are strongly controlled by exchanges of water and solutes with adjacent river banks and uplands (Sikdar et al, 2001;Ray et al, 2002). Ground-and surface water can be seen as linked components in a larger hydrological continuum that should be considered for sustainable development (Eikenberg et al, 2001;Négrel et al, 2003).…”

This study presents strontium isotope and major ion data of shallow groundwater and river water from the Ile du Chambon catchment, located on the Allier river in the Massif Central (France). There are large variations in the major-element contents in the surface-and groundwater. Plotting of Na vs. Cl contents and Ca, Mg, NO 3 , K, SO 4 , HCO 3 , Sr concentrations reflect waterrock interaction (carbonate dissolution for Ca, Mg, HCO 3 and Sr because the bedrock contains marly limestones), agricultural input (farming and fertilising) and sewage effluents (for NO 3 , K, SO 4 ), although some water samples are unpolluted. Sr contents and isotope ratios ( 87 Sr/ 86 Sr vary from 0.70892 to 0.71180 along the hydrological cycle) in the groundwater agree with previous work on groundwater in alluvial aquifers in the Loire catchment. The data plot along three directions in a 87 Sr/ 86 Sr vs. 1/Sr diagram as a result of mixing, involving at least three geochemical signaturesAllier river water, and two distinct signatures that might be related to different water-rock interactions in the catchment. Mixing proportions are calculated and discussed. The alluvial aquifer of the Ile du Chambon catchment is considered, within the Sr isotope systematic, in a larger scheme that includes several alluvial aquifers of the Loire Allier catchment.

“…Stream-aquifer interactions have been studied under various settings such as during regional groundwater management projects [1,2], contaminant transport and remediation investigations at the stream-aquifer interface [3][4][5], projects aimed at estimating hydraulic parameters [6][7][8][9][10], and investigations of the hydraulic connectivity between a stream and an aquifer system [11][12][13][14]. In particular, stream-aquifer interactions have increasingly become a critical issue for water resources management and such interactions are now being emphasized in applications involving hydrological, environmental, ecological, and hydrogeological problems in the riparian/hyporheic zone.…”

This study investigated changes in stream-aquifer interactions during the period shortly after the construction of the Changnyeong-Haman River barrage (CHRB) on the Nakdong River in South Korea. The hydraulic diffusivity (α) and river resistance (R) values at the semipervious stream-aquifer interface were estimated by using a one-dimensional (1-D) analytical solution with Fourier transform (FT). Prior to the application of the 1-D analytical solution, the noise effects on the groundwater levels were removed by using fast Fourier transform and low-pass filtering techniques. Sinusoidal variation of the river stages was applied to the 1-D analytical solution. For the study period, the R values showed a decreasing trend, while the α values showed an increasing trend, and results showed that the average of the median values of flood duration times (t d ) and flood amplitudes were reduced to 78% and 59%, respectively. Moreover, the ratio of flood peak time to t d demonstrated a decreasing tendency after the construction of the CHRB. Hence, it is concluded that the dredging and increase of river-water storage due to CHRB construction enhanced stream-aquifer interactions during the period shortly after the construction of the CHRB.
