The shape or morphology of a river channel controls how much water it can carry and how fast it flows. In this video, we team up with fluvial geomorphologist Dr Hywel Griffiths and fieldwork specialist Sam Hawkins, to explore how we can investigate this in the field by measuring the width, depth, wetted perimeter and slope of a river channel.
