bed load

Bed load rolls slowly along the floor of the stream.

It is estimated that the dam stops 50% of the bed load transport.

There are two main ways to transport bed load: traction and saltation.

They carry huge amount of bed load.

The zone contains both suspension sedimentation and bed load.

Also important to channel development is the proportion of suspended load sediment to bed load.

A soil conservation program was launched in the catchment and bed load traps were installed to minimise loss of earth.

Bed load is complementary to suspended load and wash load.

Pools are deeper and calmer areas whose bed load (in general) is made up of finer material such as silt.

Bed load transport by natural rivers.

As the bed load is an important component of that, it plays a major role in controlling the morphology of the channel.

Bed load transport rates are usually expressed as being related to excess dimensionless shear stress raised to some power.

The term Bed load is used to describe the material carried by a river by being bounced or rolled along its bed.

Suspended load, bed load, and dissolved load are included in measurements.

Roughly four-fifths is thought to move as bed load including saltation, leaving only one-fifth to be accounted for by suspension.

Bed load moves by rolling, sliding, and/or saltating (hopping).

Whereas the upper reaches are only gently inclined, the stream gets steeper beneath, forming banks of bed load.

These formulas are often segregated into bed load, suspended load, and wash load.

Attrition is a form of coastal or river erosion, when the bed load is eroded by itself and the bed.

The term bed load or bedload describes particles in a flowing fluid (usually water) that are transported along the bed.

The required Rouse numbers for transport as bed load, suspended load, and wash load, are given below.

Due to the difficulty of estimating bed load transport rates, these equations are typically only suitable for the situations for which they were designed.

Pendant bars are thin, sharp-crested deposits, and are typically made up of courser sediment from the bed load.

Bed load is generally thought to constitute 5-10% of the total sediment load in a stream, making it less important in terms of mass balance.

The dislodged particles move downstream a short distance where they fall to the bed, again loosening bed load particles upon impact (Ritter, 2006).
