The River Styles Framework is a scientific tool used to describe and explain the diversity and distribution of river types in a catchment according to river character and behaviour.[1] The River Styles Framework is based on the science of fluvial geomorphology. Each river type is called a "River Style" and its name is constructed following a consistent naming convention.[2] The River Styles Framework provides an open-ended process for interpreting rivers rather than fitting them into pre-existing categories.[1][3] The River Styles Framework is designed to provide a scientific basis for river management. It was developed by researchers at Macquarie University.[4]
