The manuscript "Wavelet and index methods for the identification of pool-riffle sequences" by Mahdade et al. presents two novel methods for the identification of pools and riffles in natural streams.These methods also allow the assessment of the main geometrical features of pools and riffles.The manuscript states that appropriate geometric description of pools and riffles is pivotal for flood modelling.I think this statement is correct when modelling floods (and flash floods) at the local scale.Conversely, previous studies have shown that simplified representations of river geometry can be a cost-effective solutions for flood modelling at the large (basin to continental scale).In fact, I believe that an accurate representation of river geometry is essential for the implementation of hydrodynamic models used for the investigation of local flow conditions and sediment transport.The scope of the paper could thus be extended to biological C1 HESSD Interactive
