Today we visited the Alden building and saw the stream table. A stream table looks like a big tub filled with sand. At one end was a water tap and over time it creates a miniature creek. We got to fiddle with the water volume and add dams. It was very interesting to watch the erosion and deposition in action. The other sand table that was in Alden was a virtual topographic map. It looked just like a topographical map but the sensor could detect the height of the sand and changed when the sand moved too. When you put your hand under the sensor it simulated rainfall on the map. Apparently there are only 50 like them in the US. I thought the building was very interesting and the professor did a really good job explaining the stream table and parts of a stream.
