KEY TO EXERCISE FOR EXPLORING 3D CONTAMINANT TRANSPORT, CONTINUOUS SOURCE
For the following
geometry:
The following parameters apply:
- Y = 10 m
- Z = 1 m
- x = 15 m
- y = 5 m
- z = 3 m
- t = 1 year = 3.16
x 107sec
- v = (K * i)/ ne
= 3.0 x 10-5m/s * 0.002 / 0.23 = 2.6 x 10-7m/s
- Dx= (v
* alpha) + D* = 2.6 x 10-7m/s * 10 m + 1 x 10-9m2/s
= 2.6 x 10-6m2/s
- Dy=
(v * alpha * 0.2) + D* = 2.6 x 10-7m/s * 10 m * 0.2 + 1 x 10-9m2/s
= 5.2 x 10-7m2/s
Dz=
(v * alpha * 0.1) + D* = 2.6 x 10-7m/s * 10 m * 0.1 + 1 x 10-9m2/s
= 2.6 x 10-7m2/s

- notice we have only
downward spreading so in the next term we use Z rather than Z/2
