DIMENSIONLESS ANALYSIS OF TWO ANALYTICAL SOLUTIONS FOR 3-D SOLUTE TRANSPORT IN GROUNDWATER

Analytical solutions provide a useful alternative approach for making screening level calculations. Domenico (approximate) and Sagar (more rigorous) analytical transport solutions were compared using dimensionless parameters (relative concentration, Peclet number,…). Results show that the errors in the Domenico solution may increase outside the plume centreline and if calculations must to be performed outside the plume centreline, the Sagar solution should be used.
