Abstract The lateral migration of a river meander is driven by erosion on the outer bank and deposition inner bank, both which are affected shear stress (and therefore channel slope) through complex morphodynamic feedbacks. To test sensitivity to slope, we quantify slope change induced glacial isostatic adjustment along Red River (North Dakota, USA Manitoba, Canada) two its tributaries over pas...

Burrowing into riverbanks by animals transfers sediment directly river channels and has been hypothesised to accelerate bank erosion promote mass failure. A field monitoring study on two UK rivers invaded signal crayfish (Pacifastacus leniusculus) assessed the impact of burrowing processes. Erosion pins were installed in 17 across a gradient burrow densities monitored for 22 months. Bank retrea...

Riparian vegetation is widely recognized as a critical component of functioning fluvial systems. Human pressures on woody including riparian areas have had lasting effects, especially at high latitude. In Iceland, prior to human settlement, native downy birch woodlands covered approximately 15%–40% the land area compared 1%–2% today. Afforestation efforts include planting seedlings, protecting ...

this study was conducted in order to sustainable conservation and utilization of trifolium genetic resources. a total of 1333 accessions of trifolium under 32 species from 27 provinces were collected according to ipgri descriptors. collected germplasms are conserved in mid- and long-term conservation at national plant gene bank of iran. statistical parameters of tendency to center and dispersio...

Vegetation in rivers and streams plays an important role preventing erosion improving bank stability. Comparison between emergent vegetation (bank vegetation) submerged vegetation, terms of velocity Reynolds stress distributions, for the same aspect ratio flow discharge, has received limited attention literature. This study investigates stress, as well log law a laboratory flume compares result...
