Field measurements of travel length in sediment transport were performed in a small experimental catchment of the Dolomites (Rio Cordon 5 km2). A set of 420 sorted marked pebbles (0.032 < D < 0.512 m) was displaced across the stream and their movements were checked periodically. These measurements are compared with the results of other authors. A dependence of transport distance on difference between flow discharge and incipient motion flow discharge is enhanced by the present research.

Abstract
Field measurements of travel length in sediment transport were performed in a small experimental catchment of the Dolomites (Rio Cordon 5 km2). A set of 420 sorted marked pebbles (0.032 < D < 0.512 m) was displaced across the stream and their movements were checked periodically. These measurements are compared with the results of other authors. A dependence of transport distance on difference between flow discharge and incipient motion flow discharge is enhanced by the present research.
