Every year more than 2500 farmers contribute their muscle power to dig and clear the sediment deposits in the canal bed.

These islands are offshore sediment deposits separated from the mainland by a body of water such as an estuary or sound.

Volcanic rocks are noted in the area as seen from the sediment deposits at the inlet.

These floods transformed the drainage valleys, repeatedly building new sediment deposits.

The Cachí reservoir is now flushed of sediment deposits on an almost yearly basis.

When rivers flood, sediment deposits in sheets across the floodplain and build up over time.

Over millions of years, the sediment deposits added to the islands until the gaps were completely filled.

This animal's sediment deposits are found in European soil dating back to between 15-30 million years ago.

The high sediment deposits have also damaged fisheries and reduced the amount of water that can be stored in a downstream reservoir.

This correlates with the estimated amount of time it would have taken to accumulate the present sediment deposits seen at the canyon head.
