The past two decades have seen significant improvements in the study of river morphology, in particular with regard to the analysis of the processes governing fluvial evolution resulting from the erosion and transport of sediments. Important results have been achieved thanks to the evolution of both instrumental and computational tools. Within the former framework, new technologies have allowed a more detailed representation of terrain (digital terrain model (DTM) obtained by light detection and ranging (LiDAR) survey), while, within the latter, the increase in the calculation speed of the latest platforms and the development of new mathematical and numerical algorithms have enabled the simulation of a much more complex phenomena. This paper discusses the application of a cellular automaton model (CAESAR) on a river reach. Simulated and measured data are compared through statistical approaches. The method is applied to a wandering stretch of River Pellice in the Italian northwestern Alps.

Abstract
The past two decades have seen significant improvements in the study of river morphology, in particular with regard to the analysis of the processes governing fluvial evolution resulting from the erosion and transport of sediments. Important results have been achieved thanks to the evolution of both instrumental and computational tools. Within the former framework, new technologies have allowed a more detailed representation of terrain (digital terrain model (DTM) obtained by light detection and ranging (LiDAR) survey), while, within the latter, the increase in the calculation speed of the latest platforms and the development of new mathematical and numerical algorithms have enabled the simulation of a much more complex phenomena. This paper discusses the application of a cellular automaton model (CAESAR) on a river reach. Simulated and measured data are compared through statistical approaches. The method is applied to a wandering stretch of River Pellice in the Italian northwestern Alps.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
