Channel patterns are types of sedimentary deposits formed by streams and rivers. Collectively, they are called fluvial deposits. Their shape and sediment characteristics are easily identified and enormously complex. Understanding of fluvial deposits is...

Landscapes form and constantly change due to weathering and sedimentation. The area where sediment accumulates and is later buried by other sediment is known as its depositional environment. There are many large-scale, or regional, environments of...

Sedimentation occurs when the velocity of flowing water is reduced, causing its load of suspended, insoluble materials to drop to the bottom (the faster water is flowing, the greater the amount of suspended material it can carry, and the larger the...

Suspended load consists of sediment particles that are mechanically transported by suspension within a stream or river. This is in contrast to bed or traction load, which consists of particles that are moved along the bed of a stream, and dissolved...

Sediment is any particulate matter that can be transported by fluid flow and which eventually is deposited as a layer of solid particles on the bed or bottom of a body of water or other liquid. Sedimentation is the deposition by settling of a suspended...

Heavy sediment deposited in the Mississippi River delta in the last ice age has caused New Orleans to sink and will continue to drag down coastal Louisiana bit by bit for hundreds of years, according to a new study by NASA and Louisiana State University...

Not far from Don's Body Shop and the Alcove Bar is a peaceful, green world that ducks, bald eagles and shorebirds call home.The Upper Mississippi National Wildlife and Fish Refuge is also a retreat for bird-watchers, canoeists and summertime boaters.But Mother Nature giveth — and...

The country's fourth-largest coal producer, Massey Energy Co., will pay a $20 million fine as part of a settlement with the government over allegations it routinely polluted hundreds of streams and waterways in West Virginia and Kentucky with sediment-filled waste water and coal slurry.Under the...

When scientists opened the watch belonging to the H.L. Hunley commander three years ago, they thought they had the key clue to why the Confederate submarine sank off Charleston.But the 18-karat gold watch now seems to raise even more questions even though scientists announced Friday...
