Fig. 5. Measured and predicted breakthrough curve (BTC) of chloride using the convection–dispersion equation (CDE) with theoretical parameter values (dotted line), and with fitted parameter values (solid line). Also shown is the prediction based on the velocity distribution measured by nuclear magnetic resonance (NMR) (broken line).
