Short summary
Channel behaviour is a qualitative aspect of river research that needs development to produce a framework of analysis between and within types of channels. We seek to produce a quantitative metric that can capture how a channel changes using a pair of experiments and collecting easy to obtain data. We demonstrate that this new technique is capable of discerning between river types and may provide a new tool with which we may describe channel behaviour.
