“…River channel pattern is a function of a variety of factors including longitudinal gradient, stream power, transport capacity, and bank strength (Buffington & Montgomery, 2022;Church, 2006;Kondolf, Piégay, Schmitt, & Montgomery, 2016). Previous studies on river pattern classification (Demarchi, Bizzi, & Piegay, 2017;Ham & Church, 2012;Horacio, Ollero, & Perez-Alberti, 2017) have been typically approached from a temporally static perspective, focusing on categorising planform at low flow. Whilst this approach is adequate for many meandering rivers in temperate regions, in other climate settings, the aerial proportions of water, exposed sediment and vegetation, which comprise the planform of a river, may substantially vary through a year (Ashworth and Lewin, 2014).…”
