Abstract:
Results of the velocity experiments at both values of specific discharge reveal select macropores with concentrated flow. The average axial components of velocity (0.016 cm/s and 0.04 cm/s) are in the range of advective flow expected in the Biscayne aquifer. Maximum Reynolds number (Re) values in the low and high specific discharge experiments are 15 and 30, respectively. Average values of Re are much lower, ranging between 1 and 6. These low Re values indicate laminar flow conditions in the model. Two further observations point to laminar flow conditions: 1) virtually all values of the axial component of velocity are positive, there are no eddies; and 2) the axial component of the velocity field is proportional between the two values of specific discharge. Exponential functions fit the distributions of the axial velocity. Distributions of the transverse component of velocity are symmetric and appear to fit a Cauchy rather than a Gaussian function.
