A Three‐Dimensional Analytical Method for Predicting Leachate Migration

A Three‐Dimensional Analytical Method for Predicting Leachate Migration This paper presents an analytical model for predicting contaminant transport from a Gaussian vertical strip source in a three‐dimensional uniform ground‐water flow field. The model takes account of hydrodynamic dispersion, adsorption, and decay. In addition, the effects of partial penetration of the contaminant source and finite aquifer thickness are accounted for. Dimensional analysis and type curve procedure are developed for evaluating steady‐state (or maximum attainable) concentration along the plume center line. Application of the type curve procedure is demonstrated. Also included in the presentation is a method for evaluating the effective decay constant of a nonconservative chemical, based on an assumption of simple hydrolysis. The proposed model has been compared with three other analytical models given in the literature. Two simulation examples are presented. Results of the comparison indicate certain advantages of the present model over its previous counterparts. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Ground Water Wiley

Abstract

This paper presents an analytical model for predicting contaminant transport from a Gaussian vertical strip source in a three‐dimensional uniform ground‐water flow field. The model takes account of hydrodynamic dispersion, adsorption, and decay. In addition, the effects of partial penetration of the contaminant source and finite aquifer thickness are accounted for. Dimensional analysis and type curve procedure are developed for evaluating steady‐state (or maximum attainable) concentration along the plume center line. Application of the type curve procedure is demonstrated. Also included in the presentation is a method for evaluating the effective decay constant of a nonconservative chemical, based on an assumption of simple hydrolysis. The proposed model has been compared with three other analytical models given in the literature. Two simulation examples are presented. Results of the comparison indicate certain advantages of the present model over its previous counterparts.
