After lunch, we also ran some more tests. This time we set up a single layer of rocks that covered the sand. We then put 6 inches of sand on top of the layer of marbles. We wanted it to try to mimic a layer of rocks in a stream. We started the column a half inch above the rocks and continued to move the column up obtaining our values need to calculate hydraulic conductivity. We will look to compare the k-values we got once we have obtained k-values from running Modflow.
