Un dispositivo per la misura del trasporto solido al fondo in correnti a bassa sommergenza

In this paper some preliminar results obtained with a new conception, non intrusive bed load gauge for laminar sheetflows are presented. The gauge, whose hardware has been derived by a conventional scanner, identifies the crossing of sediments through a control section operating on the basis of automated visual inspection. An on-line operating interface software allows particles recognition and counting. As an example of application, the problem of the onset of sediment transport is considered.
