Abstract |
The objective of the research agreement was to develop mathematical models to quantify the concentration variability observed in field measurements of concentration plumes. The concentration variability is attributed mainly to spatial heterogeneity of the hydraulic conductivity field. Since there is limited information about actual distributions of hydraulic conductivity in a given site, the log-hydraulic conductivity is modeled as a three-dimensional anisotropic stationary random process. It is shown that the concentration variance, which measures the intensity of the variations, is proportional to the mean concentration gradient and to the variance and correlation scales of the log-hydraulic conductivity; it is inversely proportional to the local dispersivity values. Analysis of a portion of the data from the Canadian Forces Base, Borden, Ontario, shows the applicability of the developed results in field situations. Simple analytical examples demonstrate the way to use the results in a predictive context. |
