| Abstract |
Methods for determining small-scale variations in aquifer properties were investigated for a sand and gravel aquifer on Cape Cod, Massachusetts. Measurements of aquifer properties, in particular hydraulic conductivity, are needed for further investigations into the effects of aquifer heterogeneity on macrodispersion, or the enhanced dispersion of solutes in aquifers. The primary methods used to measure vertical profiles of hydraulic conductivity were multiple-port permeameter analysis of cores and impeller-flowmeter hydraulic tests in long-screened wells. More than 1,600 hydraulic-conductivity measurements have been made using these methods. Several other methods of measuring aquifer properties also were investigated, including piezometer tests, geophysical borehole logs, and ground-penetrating radar. |
