bed load

[′bed ‚lōd]
(geology)
Particles of sand, gravel, or soil carried by the natural flow of a stream on or immediately above its bed. Also known as bottom load.

However there is uncertainty over whether animals can hear turbines over naturally occurring ambient noise in these energetic sites (from water flow, bed load transport and turbulence).
Since sediment transport is related to a power of the bed shear stress (typically quadratic for bed load and cubic for suspended load), small errors in predicted bed shear stress can result in large errors in predicted gross and net sediment transport.
The SSC is very small when [gamma]=50, so the bed load is the dominant composition when [gamma][greater than or equal to]50.
Particle percentage of suspended sediment, bed sediment, suspended sediment discharge and bed load discharge were entered to software.
The model covers a domain that spans from Donaldsonville to the Gulf of Mexico (190 river miles) and will carry precisely selected and calibrated synthetic sand to simulate the bed load transport characteristics of the Mississippi River.

Among the topics are one-dimensional finite volume simulation for large boulder transport, the rheological behavior of pyroclastic debris flow, soil moisture retrieval with remote sensing images for debris flow forecast in humid regions, experience treating road structure landslides by innovative methods of deep drainage, the distribution of debris flows and debris flow hazards in southeast China, regional methods for evaluating shallow landslide hazard in Italy and Central America, restoring the degraded torrential Arroyo del Partido stream in Spain with a flood control system, and dynamics of changes in bed load outflow from a small glacial catchment in West Spitsbergen.
The bed load transport was measured on the same days, with the exception of 2 July.
El muestreo de arrastre de fondo se realizo mensualmente y durante algunos eventos de crecida en la localizacion de la estacion fluviometrica, utilizando un tomador de muestras de lecho (o bed load sampler) tipo Helley-Smith, segun lo indicado por Simons y Senturk [3], Whittaker [13] y Slattery y Burt [16].
It was suspected that during these stages the bed started to develop an armoured bed where the bed load transport rate almost constant during the last three hours of AF-6.
The Bobcat 2300 travels at speeds up to 25 mph, features a rust-proof aluminum frame and comes with a standard power-cargo dump box with an 800-pound bed load capacity.
What has to be done now is to let the Mississippi River take its natural course and allow the full bed load of the river to rebuild the marsh." He adds, "The problem with Coast 2050 and other restoration plans is that they fail to halt wetland destruction in the same areas they are trying to restore.
