Electrical anisotropy can play an important role in estimating the orientation of hydraulic conductivity in aquifers. Knowledge of hydraulic anisotropy can aid modeling of groundwater flow as anisotropy in rocks of aquifer may indicate a preferred hydraulic conductivity direction, which has been formed through fracturing, sedimentary fabric or dissolution. In the present study, a 28-electrode resistivity imaging system was used to investigate electrical anisotropy at 13 sites in the Biscayne Aquifer of SE Florida using the rotated square array method. The measured coefficient of electrical anisotropy generally ranged from 1.01 to 1.12 with values as high as 1.36 found at one site. Higher values were generally located on the Atlantic Coastal Ridge while the lowest values were in low elevation areas on the margin of the Everglades to the west. The observed electrical anisotropy was used to estimate an anisotropic component of the secondary porosity and hydraulic anisotropy (ratio of maximum to minimum hydraulic conductivity) which ranged from 1 to 11% and 1.18 to 2.83 respectively. The predominate trend of minimum resistivity and maximum hydraulic conductivity was EW/SE-NW beneath the ridge and E-W/SE-NW farther west. The high anisotropic values found on the ridge may be a result of increased dissolution rates of the oolitic facies of the Miami Formation limestone compared with the bryozoan facies to the west. The anisotropy directions are similar to the predevelopment of groundwater flow direction as
