|
C0 |
source concentration |
x, y, z |
evaluation locations |
t |
evaluation time |
vx |
velocity in x direction (it is assumed that velocity only has an x component); this can be divided by the retardation factor to model sorption |
ax, ay, az |
dispersivities (units of length) in x, y and z directions |
lambda |
first-order decay constant |
sY, sZ |
source dimensions in y and z directions |
dur |
duration of pulse |
const_Dom
returns the solution from a constant source which
starts at time 0. square_Dom
returns the solution from a finite
duration constant source that starts at time 0 and stops after
dur
.
Numeric result, of same form as x, y or z. x, y and z may be recycled.
Some special cases may be achieved with certain parameter sets.
If lambda = 0 (no degradation), the Domenico-Robbins (1985) solution
results.
If ax = 0 (no longitudinal dispersion), the Domenico-Palciauskas (1982)
solution results.
If ay = az = 0 (no transverse dispersion), the Bear (1979) solution
results.
If ay = az = 0 and lambda = 0, the Ogata-Banks (1961) solution
results.
