Characterization of Stream Meanders for Stream Restoration [PDF]
Journal of Hydraulic Engineering, 1997 Recently increased emphasis and attention has been given to river management and restoration of modified streams. A variety of restoration techniques and objectives exist, including asymmetrical cross-section construction, point bar development, two-stage channel design, floodplain approaches, pools and riffles re-creation, and sinuosity and meander ...

A Modification of the Biotic Index of Organic Stream Pollution to Remedy Problems and Permit Its Use Throughout the Year [PDF]
, 2018 The biotic index of the arthropod fauna of streams is modified by limiting to ten the number of individuals in each taxon used in its calculation. This reduces detrimental effects on the index of certain fairly tolerant taxa in clean streams, effects of ...

The Many Streams of the Magellanic Stream [PDF]
The Astrophysical Journal, 2008 AbstractAs a part of the ongoing H i survey by the consortium for Galactic studies with the Arecibo L-band Feed Array (GALFA-HI), we have recently imaged the tip of the MS and found several long filamentary structures. This demonstrates that the northern portion of the MS, which has been interacting with the Galactic halo for a long time, is more ...

Ordering in bidirectional pedestrian flows and its influence on the fundamental diagram
, 2012 Experiments under laboratory conditions were carried out to study the ordering in bidirectional pedestrian streams and its influence on the fundamental diagram (density-speed-flow relation). The Voronoi method is used to resolve the fine structure of the

Veronico beccabungae-Mimuletum guttati, a new plant community in Slovakia
Acta Societatis Botanicorum Poloniae, 2018 Vegetation with high coverage by the alien species Mimulus guttatus was studied in the hilly regions of central Slovakia in 2015 and 2016. The floristic composition of these stands was recorded in ten phytosociological relevés corresponding to the ...

Stellar Streams as Probes of Dark Halo Mass and Morphology: A Bayesian Reconstruction
, 2011 Tidal streams provide a powerful tool by means of which the matter distribution of the dark matter halos of their host galaxies can be studied. However, the analysis is not straightforward because streams do not delineate orbits, and for most streams ...
