The effect of hydrographs on bed load transport and bed sediment spatial arrangement
(AMER GEOPHYSICAL UNION, 2012)
Field measurements of sediment transport in gravel bed rivers often reveal hysteretic effects due to differences in sediment availability between the rising and falling limbs of a flood hydrograph. However, only a small ...
Vegetation and topographic controls on sediment deposition and storage on gully beds in a degraded mountain area
(2009-05)
Active gully systems developed on highly weathered or loose parent material are an important source of runoff and sediment production in degraded areas. However, a decrease of land pressure may lead to a return of a partial ...
Estimation of Concentration and Load of Suspended Bed Sediment in a Large River by Means of Acoustic Doppler Technology
(American Society of Civil Engineers, 2014-03)
The standard experimental methods used for sampling suspended loads in large rivers are usually time consuming, unsafe, rather expensive, and have a limited spatial resolution. Acoustic Doppler current profilers (ADCPs), ...
Flow-sediment turbulent ejections: interaction between surface and subsurface flow in gravel-bed contaminated by fine sediment
(MDPI, 2020)
Several researchers have studied turbulent structures, such as ejections, sweeps, and outwards and inwards interactions in flumes, where the streamwise velocity dominates over vertical and transversal velocities. However, ...
Highly seasonal suspended sediment and bed load transport dynamic in tropical mountain catchments
(Instituto Geofísico del Perú, 2016-09)
Hydrology and sedimentology development have been very limited in Peru in comparison to other sciences due to a lack of reliable suspended sediment data. A new na-tional suspended sediment yield (SSY) dataset (1948-2012) ...
Dynamics of sediment transport in two subtropical plain rivers of South America
(Schweizerbart, 2006-12)
Two rivers located in the subtropical Chaco</place /> plain are compared in order to analyse the sediment transport dynamics. Gauging and sediment samples were obtained during different hydrological stages. Grain size and ...
Definition of critical hydrodynamic conditions for sediment motion initiation using optical technique
(WSEAS Transactions on Fluid Mechanics, 2017)
Meiobenthic communities of seagrass beds (Zostera capricorni) and unvegetated sediments along the coast of New South Wales, Australia
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2011)
Seagrass beds have higher biomass, abundance, diversity and productivity of benthic organisms than unvegetated sediments. However, to date most studies have analysed only the macrofaunal component and ignored the abundant ...
