A continuous source of a contaminant is located near the intersection of two boundaries. The southern boundary is an impermeable wall, while the western boundary by some mechanism maintains a constant concen-trationC0along its length. Using the principle of superposition, describe how you can predict the concentration field in the Northeast quadrant.
