In these environments the exchange of water and solute depends primarily on the hydraulic gradient between the reservoirs. We hypothesize that daily changes in river stage associated with anthropogenic water releases (such as those from a hydroelectric dam) cause anomalous mixing in the near-stream environment by creating large hydraulic head gradients between the stream and adjacent aquifer. We present field observations of hydraulic gradient reversals in a shallow aquifer. Important physical processes observed in the field are explicitly reproduced in a physically based two-dimensional numerical model of groundwater flow coupled to a simplistic surface water boundary condition. Mass transport simulations of a conservative solute introduced into the surface water are performed and examined relative to a stream condition without stage fluctuations. Simulations of 20 d for both fluctuating river stage and fixed high river stage show that more mass is introduced into the aquifer from the stream in the oscillating case even though the net water flux is zero. Enhanced transport by mechanical dispersion leads to mass being driven away from the hydraulic zone of influence of the river. The modification of local hydraulic gradients is likely to be important for understanding dissolved mass transport in near-stream aquifer environments and can influence exchange zone processes under conditions of high-frequency stream stage changes.}, keywords = {$\#$Hydro, $\#$WaterResources, aquifers, boundary conditions, Charlemont, Deerfield River basin, fluctuations, fluvial features, Franklin County Massachusetts, ground water, human activity, Hydrogeology 21, hydrology, massachusetts, numerical models, preferential flow, rivers, shallow aquifers, streams, surface water, transport, two-dimensional models, United States, valleys}, isbn = {0043139719447973}, url = {http://onlinelibrary.wiley.com/doi/10.1029/2007WR006526/full}, author = {David F Boutt and Brandon J Fleming} } @techreport {258, title = {Hydrogeologic investigation of the west Charlemont aquifer, Charlemont, Massachusetts}, year = {2007}, pages = {116}, institution = {Massachusetts Geological Survey}, abstract = {

The University of Massachusetts Department of Geosciences and Office of the Massachusetts State Geologist were asked by the Franklin Regional Council of Governments to make an assessment of the extent, thickness and hydraulic properties of the West Charlemont aquifer located in valley fill deposits along the Deerfield River in the Town of Charlemont, Massachusetts. Previous work by Gay et al. (1974) mapped these fill deposits as a medium yield aquifer (51 gallons per minute, gpm, to 200 gpm). The purpose of this investigation is to evaluate further the potential of this medium yield aquifer as a viable groundwater resource for the Town of Charlemont. Results from six new seismic refraction surveys, three new boreholes, analysis of grain size distribution curves and a review of previous borehole logs and geophysical surveys were compiled to build a conceptual 3-dimensional visualization of the aquifer system. These data were used to make a first-order estimate of potential yield.
