Abstract

Abstract: Based on detailed analysis of uncertain factors in the process of numerical simulation, an advanced first order second moment method (AFOSM) is proposed. The method is then applied to the reliability analysis of groundwater allowable withdrawal in the riverside well field. The evaluation result shows that the risk of over-pumping is 19.31% under abstraction of 4.7×10⁴ m³/d, with consideration of the randomness of parameters.

Key words: riverside well field, numerical simulation of groundwater flow, uncertainty, risk analysis
