TL;DR: A two year survey using stationary driftnets detected mean plastic abundance and mass in the Austrian Danube to be higher than those of drifting larval fish and industrial raw material accounted for substantial parts of the plastic debris.

TL;DR: In this article, the authors observed the dispersal patterns of marked larvae of the nase carp (Chondrostoma nasus L.) alongside dissimilar shoreline configurations in the main channel of the free-flowing Austrian Danube and compared with those of floating particles to investigate the mode of dispersal (active- passive).

TL;DR: In this paper, three variants of two-equation models, i.e. the standard k-ϵ model and two variants of k-ω models, were applied to tackle mean flow and turbulence in a racetrack flume and a river reach.

TL;DR: It is found that activity in larval downstream dispersal was independent of developmental stage or current speed at release, although activity was higher during low flow conditions.

TL;DR: In this article, experiments were conducted for three low subcritical Froude numbers typical for natural streams that complement the froude number range investigated in previous studies, and the analysis of the energy production and the vorticity equations was performed to substantiate this observation.
