The study focused on the characterization of grain size, petrographic content, and degree of rounding. The analysis considers the morphology of the river channel, sources of material influx to the  fluvial system, and degree of human impact. Research has shown that variances in alluvia in the Lepietnica are determined largely by catchment geology and regional elements of relief. Mountain areas such as the Gorce Mountains are characterized by the alluvia of larger grain size, more complex petrography, and less rounding. The lower stretch of the Lepietnica found in the Nowotarska-Orawska Basin is characterized by alluvia of smaller grain size, more rounding, and a different petrographic content.
