Abstract

Kinematic mixing theory is used to analyze reactive transport in random velocity fields. The theoretical results indicate that the field-scale reaction rate is strongly related to the spatial structure of the velocity field, which in turn is related to the autocovariance of logK. The theoretical results are verified by numerical experiments. 1 Introduction In real world environment protection practice, one of the most frequently asked questions is "How far will a contaminant plume migrate before it biodegrades?". To predict the plume behavior, it is necessary to estimate: (1) the rate of migration; and (2) the rate of biodegradation. The rate of contaminant migration can be estimated by measuring the hydraulic gradient and perme
