| Zusammenfassung |
| Statistical outcomes and Einstein predictors of ordinary bed-load transport processes have
been obtained through an innovative experimental methodology that applies to flows where
the bed is flat and made of well sorted particles. Two major findings are presented. The first
one is a confirmation of Einstein’s assumption about average grain displacement, the
distance run between two subsequent resting periods, which is showed to scale with
the grain-size only, at given bed slope. The second achievement consists of the
probability density function of the grain resting time. This information about the ordinary
bed-load regime may be exploited in mechanical/statistical interpretations or in the
determination of associated features, e.g., the dispersion of pollution carried by the grains. |
