pyRiverBed: A Python framework to generate synthetic riverbed topography for constant-width meandering rivers

Meandering is one of the unique processes in Earth surface dynamics. Since 1960s, fluvial geomorphologists have generalized numerous widely-acknowledged empirical or semi-empirical formulae to describe meandering rivers' characteristics. The most frequently applied Kinoshita high-sinuosity curve meander channel planform geometry. Combining with Beck equations riverbed topography at equilibrium state, a prototype synthetic generating model made for idealized rivers. Such method can be readily extended and arbitrary rivers real world, resulting model, pyRiverBed, presented herein. A migration neck cutoff submodel also embedded pyRiverBed. Unlike existing linear non-linear bend theory-based models, pyRiverbed aims towards each snapshot during process. present facilitate river researchers interpolate their field-measured bathymetric data using bed, design non-flat bed laboratory flumes experiments, initialize hydrodynamic morphodynamic numerical models. It provide guidance stream restoration projects on designing bed. quality generated evaluated through comparison against both experiment data. validated real-world event. validation results prove that riverbed's accuracy reasonably good, successfully predict cutoff. • We propose Python-based generate work curve-defined channels. load user-provided centerlines. finite element mesh file flow sediment simulations. integrates detection submodel.
