What do you call the lands bordering a river that are subject to flooding?
A floodplain or flood plain or bottomlands is an area of land adjacent to a river which stretches from the banks of its channel to the base of the enclosing valley walls, and which experiences flooding during periods of high discharge.
What is it called when rivers flood?
Fluvial (River Flood) Fluvial, or riverine flooding, occurs when excessive rainfall over an extended period of time causes a river to exceed its capacity.
What is a floodplain in a river?
Definition: A flood plain is an area of flat land alongside a river. This area gets covered in water when the river floods. Flood plains are naturally very fertile due to the river sediment which is deposited there.
What part of a stream valley is covered by water during a flood?

|---|---|
| floodplain | part of the valley floor that may be covered with water during a flood |
| gradient | change in elevation over a distance |
| groundwater | water that soaks deep into soil and rock |
| headward erosion | lengthening and branching of a stream |
What are river cliffs?
A cut bank, also known as a river cliff or river-cut cliff, is the outside bank of a curve or meander in a water channel (stream), which is continually undergoing erosion. They are shaped much like a small cliff, and are formed by the erosion of soil as the stream collides with the river bank.
What is floods in rivers and coastal areas?
River floods are caused when consistent rain or snow melt forces a river to exceed capacity. Coastal floods are caused by storm surges associated with tropical cyclones and tsunami.
What is the land on each side of a river called?
The passage where the river flows is called the river bed and the earth on each side is called a river bank.

What does River Cliff mean in rivers?
As a river goes around a bend, most of the water is pushed towards the outside. The lateral erosion on the outside bend causes undercutting of the bank to form a river cliff . Water on the inner bend is slower, causing the water to slow down and deposit the eroded material, creating a gentle slope.
Is the land around a river called a flood plain?
The land surrounding a river is called a flood plain. Coastal flooding, also called estuarine flooding, happens when a large storm or tsunami causes the sea to rush inland. Floods are the second-most widespread natural disaster on Earth, after wildfire s.
Which is the western boundary of the Mississippi River?
The Great Divide is the western boundary of the Mississippi River, and the Eastern Continental Divide is the eastern boundary of the Mississippi. What is the level or nearly level land that borders a river and is covered by river water in flood time called?
What kind of floodplains are found in river valleys?
Older floodplains and river valleys can have many fluvial terraces. The Rhine Valley of Central Europe, for instance, has dozens of fluvial terraces created by the meandering Rhine as well as intense glaciation. Fluvial terraces in the Rhine allow geologist s to examine more than 100,000 years of Europe’s past.
What happens when a river overflows its banks?
However, floods have enormous destructive power. When a river overflows its banks or the sea moves inland, many structures are unable to withstand the force of the water. Bridges, houses, trees, and cars can be picked up and carried off. Floods erode soil, taking it from under a building’s foundation, causing the building to crack and tumble.
