Explaining High Celerities and Velocities in Vadose Zone Fractures

Preferential flow is common in the vadose zone of bedrock aquifers. Rapid film flow down fracture walls and free-fall flow down open vertical fractures produce velocities that are commonly in the range 10<sup>-4</sup> to 10<sup>-1</sup> m/s.

Abstract

Preferential flow is common in the vadose zone of bedrock aquifers. Rapid film flow down fracture walls and free-fall flow down open vertical fractures produce velocities that are commonly in the range 10<sup>-4</sup> to 10<sup>-1</sup> m/s.
