3. What are the sediments ?
Sediments are the small particles (i.e.- Soil Particles)
which are the natural occurring materials that is broken
down by the process of weathering and erosion, and is
subsequently transported by the action of wind, water or
ice and by the force of gravity acting on the particles.
Sentiment is the accumulation of dirt and sand at the
bottom of Lakes.

5. Types of Sediments
•Clastic and Biogenic Sediments
•Clastic sediments, which are composed of clast
(smaller grain of rock broken off other rocks by
physical weathering.
•Biogenic Sediments, which are defined as containing
at least 30 % skeletal remains of marine organisms,
cover approximately 62% of the deep ocean floor.

7. Factor affecting the Sediment yield
•There are so many factors having impact on
sediment yield, but there are only four important
factor which are following-
•Vegetation
•Rainfall
•Soil
•Topography

8. Factor affecting the Sediment yield
Surface geology soils Marine shales
Easily disperesed, high shrink-swell characteristics
Climate Infrequent convective storms, freeze-thaw occurrence
Runoff High peak flows; low volumes
Topography Moderate slopes
Ground cover Sparse, little or no litter
Land use Intensive grazed
Upland erosion More than 50% rill and gully erosion
Channel erosion Occassionally eroding banks and bed but short flow duration.

9. Sediment transportation
Sediment transport is the movement of solid particles (sediment),
typically due to a combination of gravity acting on the sediment,
and/or the movement of the fluid in which the sediment is
entrained. Sediment transport occurs in natural systems where the
particles are clastic rocks (sand, gravel, boulders, etc.), mud, or clay;
the fluid is air, water, or ice; and the force of gravity acts to move
the particles along the sloping surface on which they are resting.
Sediment transport due only to gravity can occur on sloping
surfaces in genera
Knowledge of sediment transport is most often used to determine
whether erosion or deposition will occur.

10. Sediment load
The solid material that is transported by a natural agent,
especially by a stream are known as Sediment load.

11. Types of Sediment load
•Bedload , Suspended load & Dissolved load
•Bedload :That portion of the sediment load that is
transported along the bed by sliding, rolling or hopping.
Bedload moves at velocity slower than the flow.
•Suspended : Particulate sediment that is carried in the body
of the flow. Suspended load moves at the same velocity as
the flow.
•Dissolved load : Material that is chemically carried in the
water.
