The annual suspended sediment load is about 430 million tons.

And that alternates with a sediment that looks like this.

Sediment, or mud, sits at the bottom of water bodies.

A 2010 National Research Council report assessed the roles of sediment in the Missouri River, evaluating current habitat restoration strategies and alternative ways to manage sediment.

The average sediment deposition at the river mouth per year is .

This requires the collection of surface water, sediment and biota samples.

The sediment pre filter removes suspended solids such as rust and sediments.

Sediments and Sediment Processes in Kane Basin, a High Arctic Glacial Marine Basin .

This sediment is 100 percent made up of the shells of microscopic plants.

18 4.5 Tanks shall be fitted with installations for breaking up sediment and cleaning.

41 For example, the effects of adding (and removing) sediment have often been neglected.

Reforesting another 14,200 hectares could cut the concentration of sediment in the watershed by half.

The Palolo, Napu, Lindu and Besoa Valleys were once lakes, now partially filled with sediment.

Lots of evidence from sediment cores and the pollen types, oxygen isotopes and so on.

Rivers washed sediment into the seas, until the organic remains of the algae were buried.

And the black rock is the sediment on the sea bottom in the absence of plankton.

In the Caribbean, more than 60 of coral reefs are threatened by sediment, pollution, and over fishing.

985 996 Modern sediment supply to the lower delta plain of the Ganges Brahmaputra River in Bangladesh.

The animals or organisms have now been extracted from the sediment for all of the samples collected.

And these plants need sunlight, so we know when we find that sediment there's no ice overhead.

Valleys filled with sediment and, during the wet times of glacial periods, with lakes, such as Lake Manly.

This resulted in a reduction of the estimated area of oil contaminated sediment to approximately 65 square kilometres.

Generated run off is less erosive and less polluting as crop residues reduce sediment transport into river waters.

These data can help in identifying phytoplankton and in estimating chlorophyll a, suspended sediment and dissolved organic matter.

These are lead scientists and researchers creating an innovative method to determine the past or present in sediment.

As seas advanced and receded over the land, successive layers of plant material and sediment were built up.

Subsurface reducing habitats occur when, within the ocean bottom sediment, anoxia is created by the microbial degradation of organic matter.

Lifespan Because the source of the Indus River is glacial meltwater from the Himalayas, the river carries huge amounts of sediment.

It doesn't matter what kind of sediment you're using to grind up, whether it's bacteria or any other plants or animals.

Well, an excavation was begun immediately, and more and more little bits of skull started to be extracted from the sediment.

Iraq's general contention is that the model predictions of subtidal sediment contamination used by Kuwait to estimate biomass losses are not reliable.

The models used are a Model for the Assessment and Remediation of Sediment ( MARS ) and an Oil Spill Contingency and Response Model ( OSCAR ).

Marine sourced material (for example, from sea water sediment) has a higher chance of being successful commercially because of its mega diversity.65

It's a basin, and rivers flow down from the highlands into the basin, carrying sediment, preserving the bones of animals that lived there.

Rice paddies need to be constantly flooded, and, because they are often located on steep slopes, this leads to significant runoff of fertilizers and sediment.

In the ponds, the heavy materials must sediment out, so that the water, when passing through the irrigation, is suitable for use in the fields.

The family Nikkasauridae also includes the Reiszia genus with two species ( R. gubini and R. tippula ) described by Ivahnenko in 2000 from the same sediment.

And we take samples of the sediment, and it tells us the CO2 level of the ocean, and therefore the CO2 level of the atmosphere.

Elevated concentrations (above natural background) of heavy metals and PCBs have been found in fish and sediment, with high levels near point sources of emission.

The sediment contributed from these two rivers forms the Bengal Delta and Submarine fan, a vast structure that extends from Bangladesh to south of the Equator, is up to 16.5 km thick, and contains at least 1130 trillion tonnes of sediment accumulating over the last 17 million years at an average rate of 665 million tons yr.

Locally, but sometimes still at a grand scale, the shock waves cause major sediment slides on steep underwater slopes such as those of the continental shelves.

It will allow the lowest bidder to receive funding for one or more best management practices that reduce nitrogen, phosphorus and sediment run off on farms.

The area has lost 70 of its original forest cover, and sediment from eroding hillsides has clogged the city s reservoir, jeopardizing the water supply of Brazil s largest city.

And all the sediment is then put through these screens, and where we go again through it very carefully, looking for small bone fragments, and it's then washed.
