The steps in this process may be combined to the following final equation:
T = 1000 x 2 / 3 k L
(assumes porosity of 33 per cent)
where the parameters and units of measurement are:
T
x
k
L
is the time to pass through liner (days)
is the depth of the impermeable layer (m)
is the predicted saturated hydraulic conductivity (mm/day)
is the distance between the level of the pond surface and the level of the base of the
impermeable layer (m) i.e. depth of water + depth of impermeable layer
The volume leaked during the period of ponding may be calculated using the following equation:
V = Q t a
86.4
Where V is the volume leaked during the period the pond is filled (ML/ha),
Q is the flow (m 3 /s),
t a
is the number of days that leakage may occur (the maximum likely filled period of the
containment structure (days) minus the time to pass through the liner (T)),
and 86.4 is a unit conversion factor from m 3 /s to ML/day.
