STUDYING RIVERS
LATEST SCIENTIFIC DEVICE. Scientists want to know what is going on below the surface in rivers and how the damage is done when they go “on the rampage.’ If left to themselves rivers don’t "stay put” but wander over the landscape cutting new beds for themselves. They carry away the valuable land in the form of silt and deposit some of it along their course, but carry more of it to the ocean. Five model rivers have been constructed at the California Institute for Technology so that scientists can learn how to prevent the waters from cutting into river banks, how rivers in flood transport boulders and gravel, how deep waterfalls erode the beds of streams, and the answers to a number of other conservation problems. The "rivers” are about two feet deep and 100 feet long. They are really only half-rivers because one side of them is a glass wall through which the scientists can observe what is happening to the bed and the opposite bank under varying conditions which they can control.
