Fluvial eco-hydraulics and morphodynamics: New insights and challenges

On the Morphodynamics of a Wide Class of Large‐Scale Meandering Rivers: Insights Gained by Coupling LES With Sediment‐Dynamics

“…Nonetheless, simulating morphodynamic processes in rivers under flood conditions poses major computational challenges for high‐fidelity numerical models (Camporeale et al., 2007; Keylock et al., 2005; Stoesser, 2014). Yet, in recent decades, several studies have attempted to model the turbulence and morphodynamics evolution of open‐channel flows (e.g., Iwasaki et al., 2016; Jia et al., 2005; Olsen & Kjellesvig, 1998; Roulund et al., 2005; Wu et al., 2000), and reviews of such studies have been reported by Termini (2015) and Armenio (2017). It should be also noted that due to the high degree of complexity involved in the modeling of riverine systems alongside the high computational cost of such simulations have limited most of past studies to two‐dimensional modeling (e.g., Begnudelli & Sanders, 2006; Castroa et al., 2008; Horritt & Bates, 2002; Iwasaki et al., 2016; Mignot et al., 2006; Yu & Lane, 2006).…”
