Sedimentation can be traced back to the Latin sedimentum “a settling or a sinking down.”

What causes sedimentation?

Sedimentation occurs when eroded material that is being transported by water settles out of the water column onto the surface as the water flow slows. The sediments that form a waterway’s bed banks and floodplain have been transported from higher in the catchment and deposited there by the flow of water.

How does silt cause flooding?

When deposits of silt are compressed and the grains are pressed together rocks such as siltstone form. Silt is created when rock is eroded or worn away by water and ice. … So deposits of silt slowly fill in places like wetlands lakes and harbors. Floods deposit silt along river banks and on flood plains.

Why is a river delta important?

Deltas absorb runoff from both floods (from rivers) and storms (from lakes or the ocean). Deltas also filter water as it slowly makes its way through the delta’s distributary network. This can reduce the impact of pollution flowing from upstream. Deltas are also important wetland habitats.
