4. The hydraulic conductivity of an array of parallel fractures in the direction parallel to the plane of the fractures is given by the equation K Age³ 12v 7 where is the fracture frequency, g is the gravitational v is the kinematic acceleration, e is the fracture aperture, and viscosity of the fluid. For a rock mass apertures of 0.01 mm, the hydraulic conductivity is 8.38 10-10 m/s. (a) What is the hydraulic conductivity of a second rock mass which has ten fractures per metre and fracture apertures of 1 mm? (10 points) (b) What is the main factor contributing to the difference in the hydraulic conductivity of the two rock masses? (20 points)
