Abstract:Considering the influences of uncertain factors of hydrodynamic dispersion coefficient and measurement error on the reliability of contaminant concentration estimation, a discussion was made on the reliability of contaminant transportation in groundwater by use of the niche-hybrid genetic algorithm, and the direct and inverse analysis of contaminant concentration was also performed under the reliability condition, providing more information for decision-making in groundwater environmental protection and regulation. The result of study shows that the niche-hybrid genetic algorithm is feasible and effective for reliability analysis of contaminant transportation in groundwater.
Keywords:groundwater pollution  contaminant transportation  niche-hybrid genetic algorithm  reliability analysis
