4. (30 pts) Groundwater flows from a homogeneous zone 1 with a hydraulic conductivity.
of K₁=2 m/day to a homogeneous zone 2 with a hydraulic conductivity of K₂=20 m/day.
The effective porosity values in zone 1 and zone 2 are 0.2 and 0.1, respectively. The
Darcian velocity in zone 1 is q₁-0.1 m/day. The hydraulic gradient is zone 1 is 0.005. The
entry angle in zone 1 is 20 degrees with the normal direction of the interface of zone 1
and zone 2. Solve the following problems:
a) What is the angle of flow in zone 2 with the normal direction of the interface of
these two zones?
b)
What is the Darcian velocity in zone 2?
c) What is the hydraulic gradient in zone 2?
d) What are the groundwater flow velocities in zone 1 and zone 2?
