Ptary of the processes discussed above have been presented in some
detail in the hydroiogy literature. All have been expressed in terms of
parameters that are modified by mining activities. The solution of
equation [8] for baseline conditions, and for conditions resulting frnm
mining activities, will give the analyst an indication of the impact
of that activity or control on runoff.
If, in equation [8], it is assumed that the soil crater-holding
capacity limits S, and is = 0.2S, then
~P - Rc/4)z
Q = P + Rc [g]
where Rc~~ < P and
Rc = the soil water recharge requirement
as previously described. .
The basis for making pre- and post-treatment determinations lies
in the ability to extract from the soil moisture methCdologies, the
chanye in anteceden*_ soil moisture conditions. In this report, soil
moisture status is estimated by simulation analysis (Tables 1 and 2).
