By turning a bottle upside down, sediment would collect in the new cork's first chamber.

The sediment collects in the Keating Channel just past the mouth of the river.

This formation was deposited during the Carboniferous period at the mouth of the ancient where sediments collected and compacted.

Such deposits and sediments collect in ocean basins today, replicating the conditions under which oil was formed in the past.

But they were aware that sediment was collecting and that leak technology wouldn't work if the lines were not periodically cleaned.

Experiments with the models convinced engineers that the auxiliary structure should be built at the inside of a river bend, where sediment collects.

The sediment collected along the shoreline, allowing the land to maintain its relative position to the sea.

Instead of being deposited on the shore, the sediment is now collecting in Lake Nassar, behind the dam.

Because of this, sediment sinks and collects in the bottom and virtually does not decay.
