We also experimented with finding the porosity of the 2 sands. This was done by filling a graduated cylinder with a known amount of water and then pouring some sand into the column. Once the sand was allowed to settle, the level of the sand and the level of the water were measured to calculate the porosity.
Tomorrow we plan on going back out to Duck Creek to do some field work. I think we are going to go to a different place along the creek and will be doing measurements that are similar to what we did the last time we were there to compare the K-values at different parts of the stream.
