Abstract

A simplified method of time domain reflectometry waveform analysis was adapted for calculation of bulk soil electrical conductivity (σa), and applied to real-time measurement of solute breakthrough in an intact soil column. Results were compared with Br- concentration and electrical conductivity (σ) of the effluent fractions. The breakthrough curve (BTC) based on σa was comparable to those using effluent analyses. Solute transport parameters estimated from the convective-dispersive equation for the σa BTC were not different from those derived from effleunt σ and effluent Br- BTCs. This measurement approach may be easily incorporated into existing computer- and datalogger-controlled acquisition and analysis systems. -from Authors
