Fig. 4. Measured and simulated drainage electrical conductivity for Phase 1 experimental treatments using various irrigation water salinities (ECiw). The open circles in each plot are measured daily averages and the solid lines are the simulated drainage EC. The horizontal line in each plot is a steady-state approximation (see Eq. [17]). Drainage was not continuous in the simulations, leading to the broken appearance of the solid lines. The irrigation for each lysimeter is shown in Fig. 3.
