You are given the following data from previous analysis of the TSF. Using these data, calculate the decant/discharge necessary for steady state.

Direct precipitation (P) = 5 * 10⁵ m³

Tailings feed (F) = 5.53 * 10³ m³

Runoff from embankment catchment area (R) = 5 * 10⁴ m³

Seepage into the embankment (d) = 1.5 * 10⁶ m³

Evaporation = 140 mm/yr

Pond area = 1.0 x 10⁷ m²
