Abstract

A Hermite series expansion is used to describe the time evolution of the contaminant concentration at a fixed location in a flow. Exact expressions are derived for the dosage, centroid and temporal variance. A two-mode approximation is proposed which gives accurate results at moderate to large distances downstream of the discharge.
