The Science of River Restoration

What basic principles do rivers adhere to? and can we restore a river if it has been degraded in some way?

The first question was first addressed, or at least one of the original persons, by Luna Leopold. He saw similarities in rivers and streams of different sizes and in different regions. If you have been to more than one river or stream then you know they can be quite different and in fact I contend that each one is unique. So what qualities or characteristics do they share. Well thats one of the things Luna found. He found patterns similar to many streams such as the meandering pattern, radius of curvature, width and depth ratios to name a few. These are all governed by the laws of physics. Patterns in nature have always fascinated me as well as many others I am sure. more to come have to do actual work
