What is it about?
Flows in natural streams are rarely uniform due to changes in hydraulic and geomorphological parameters, and non-uniform flows over cobble beds in the presence of vegetation are frequently observed. This paper showed how hydraulic and hydrodynamics parameters changes over cobble bed streams with submerged vegetation in the laboratory and field.

Why is it important?
In the present study, the effect of non-uniform flow (FPG) over a cobble bed with a vegetated strip on turbulence characteristics was investigated in both a laboratory flume and an actual river.
Perspectives
The authors walked more than 10 km to find flow conditions without the occurrence of either erosion or sediment deposition. Also, the aim of the work was not to model the river in the laboratory, but to explore the hydrodynamic implications of the presence of a submerged vegetation strip on a cobble bed under non-uniform flow in both the laboratory and field.
