Summary/Abstract: The operation problem of Horizontal Subsurface Flow Constructed Wetlands (HSFCW) to remove pollutants under uncertainty is investigated numerically in a stochastic way. Uncertain-but-bounded input-parameters are considered as interval parameters with known upper and lower bounds. This uncertainty is treated by using the Monte Carlo method. A typical pilot case of an HSFCW concerning Biochemical Oxygen Demand (BOD) removal is presented and numerically investigated. The relevant numerical results have a good matching to available experimental ones, and so the effectiveness and the reliability of the proposed stochastic approach is proven.
