Probabilistic design of mine-site ponds using a dynamic water management model

Water management at a mine site is a critical component for the design of ponds for mine facility operation and mine facility closure. A comparison of pond sizes designed using both a probabilistic and deterministic dynamic water balance model is made. In this sense, the paper point out the probabilistic design of mine-site ponds using a dynamic water management model. The two models both have the capability of using actual operational data and climate inputs to give storage requirements of the ponds Both short-term (60 days) and longterm (many years) designs incorporating a user-selected storm event and a probabilistic or deterministic analysis may be utilized for calculating storage volumes for various mine facilities. Based on these, operational decisions based on actual values or probabilities over time can be made.
