We have measured the horizontal and vertical electromagnetic velocity through an alluvial, sandand-<br>cobble aquifer near Boise, Idaho. To measure the horizontal velocity, we deployed antennas in two<br>wells 6.9 m apart. To measure the vertical velocity, we placed one antenna on the surface adjacent to a<br>well and lowered the other antenna down that well. We collected data at three wells; two wells at either<br>end and a well located in between the two end wells. We thus have one measure of the horizontal velocity<br>and three measures of the vertical velocity. The horizontal and vertical velocity are essentially the same<br>below the water table at 2 m depth. In the vadose zone, the velocities differ, but we think that refracted<br>waves cause the velocity differences. The directional independence of the velocities indicates that we can<br>assume isotropic models in our interpretation of the aquifer.
