A sprinkler adds 15 cm of a bromide solution (i.e.,15 cm3 of water for each 1 cm of area) at a rate of 2 cm h-1. The volumetric water content (Theta) of the soil is 0.30 cm3 cm-3. Assume negligible interaction between the Br- and the soil.
What will be the depth of the Br- front after the 15 cm bromide solution is added?
At what time will the bromide front pass the 10 cm soil depth?
