The flood also deposited sediments in many places, causing lasting problems.
For example, a mountain river depositing sediment into a freshwater lake would form this kind of delta.
The glaciers from the north deposited sediments that now make up the foundation of Long Island.
However, over time, these rivers have deposited sediment as well, making Lake Chad nearly disappear in the past.
Paleochannels form when river channels aggrade, depositing sediment on their bed.
Glacial Lake Calgary was formed in the area and deposited sediments on the side of the hill.
The oxbow was created as the river's faster water eroded the outer bank while the slower inner flow deposited sediment.
Tsunamis that resulted from the earthquakes deposited sediments from the ocean onto the coast.
Though they are also common in wetter climates where streams are nearly continuously depositing sediment.
Over time, the creeks deposited enough sediment to fill the inlets with alluvium and create the present-day valley floor.
