During floods, what happens to water at the banks of a river?
Water speeds up and erodes the banks
Water is slowed and silts are deposited
Water evaporates quickly
Water freezes and forms ice
Explain how the process of silt deposition and levee formation can lead to the river flowing above the level of the flood plain over time.
Silt deposition lowers the riverbed, causing the river to flow below the flood plain
Each flood builds up the levees and riverbed, eventually raising the river level above the flood plain
Levee formation causes the river to dry up
Silt deposition has no effect on river level
