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.

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

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

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

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 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.

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.

Some fishermen carried out underwater filming at various points along the bay, where they are concerned that there is a large mass of dead or dying fish at depths that vary between 5 and 20 meters and also a large accumulation of sediment associated with industrial activity (fishing).
