\( \sum f(x) = F(x) + g(x) \)


\(A_{sv} = (A_{sd} * Sn_w) - I_{vol}\)

Where:

$$A_{sv}$$ = Average snowmelt volume (depth/unit area) $$A_{sd}$$ = Average snowpack depth at the initiation of the snowmelt period $$Sn_w$$ = Typical snowpack water at time of melt $$I_{vol}$$ = Estimated infiltration volume likely to occur during a 10-day melt period.
