Question: 2. Evaluate diffusion with groundwater upwelling at 0.01 cm/day and 1 cm/day in a sediment environment assuming that mass transfer resistances at the sediment-water interface

2. Evaluate diffusion with groundwater upwelling at 0.01 cm/day and 1

2. Evaluate diffusion with groundwater upwelling at 0.01 cm/day and 1 cm/day in a sediment environment assuming that mass transfer resistances at the sediment-water interface are negligible. Assume the concentration of the sediment is initially uniform at the concentrations and in the sediment of problem 1. Plot flux versus time from the sediments for the various cases and compare to the diffusion case previously considered. Assume a dispersivity of order 1 cm
