How are deltas and flood plains formed?

Answer 1

The amount of water being transported in a particular stream at any given

time varies with weather conditions. Sometimes, more water pours into a stream than the banks of the stream channel can hold. a FLOOD occurs when water spills over the sides of a stream's banks onto the adjacent land. The board, flat area that extends out from a stream's bankand is covered by excess water during times of floodingis know as the stream's FLOODPLAIN. Floodwater carries along with it a great amount of sediment eroded from Earth's surface and the sides of the stream channel. As floodwater recedes its volume and speed decrease, the water drops its sediment load onto the stream's floodplain creating Levees on the valley floor. Floodplain develop highly fertils soils as more sediment is deposited with each subsequent flood. These fertile soils have historically enticed farmers to use the land for crop production, even at the risk of losing homes and crops to subsequent flooding.

I'm really sure from what i wrote.

That's what "Geology, the Environment, and the Universe"'book says.

The information in this paragraph is based on information that had been taken from the National Geographic Socity.

Answer 2

you see flodplains are created by lots of people pooing and slashing leaving the area to flood and over time it floods into a floodplain after you have slashed by T.B you see flodplains are created by lots of people pooing and slashing leaving the area to flood and over time it floods into a floodplain after you have slashed by T.B you see flodplains are created by lots of people pooing and slashing leaving the area to flood and over time it floods into a floodplain after you have slashed by T.B

Answer 3

Deltas and floodplains are built up because the river brings sediment to the banks of the water. The floodplain is still prone to flooding and the delta is farther away from the water, with more sediment.

Answer 4

A flood plain is a large, flat ,low lying area often of triangular shape adjacent to one or more large rivers.The flood plain is made of of sediment of eroded material that has been tranported by the current or historical rivers ,down stream towards the sea.The Flood plain is made up of the deposits of sediment during flood times, over thousands of years.In many areas of the world such as Egypt and Bangladesh the farmers rely on the regular floding to supply a new source of fertile soil and supplies of water for a long dry season .It is commonly stored in tanks or small lakes in places like India.A flood plain is a zone of deposition -usually near the coast, for material that has been denuded from mountains inland.

In the South Island of NZ it has been calculated that the Southern Alps were at one time twice their current height (a mean height of 3,000 metres.) The eroded soil has been deposited by rivers in the ocean over millions of years until it reached what was an island off the East coast. That island -Banks Peninsula, is now part of the South Island.10 major rivers continue to transport huge amounts of rock material each year ,eastwards towards the sea.

The amount of flooding that a flood plains experiences depends on the size of the watershed ,the amount of rainfall ,the amount of snow melt, the height of any natural or manmade banks, the size of the material being transported and the gradient of the river.

Answer 5

Because the land in these areas is particularly low lying in comparison to the local water level, therefore any increase in that level because of rain, snowmelt, stormsurge, etc more easily floods the surrounding land.

Answer 6

Deltas are formed when sediments carried by rivers are deposited at their mouths due to a decrease in flow velocity, creating a fan-shaped land formation. Floodplains are flat areas adjacent to rivers that are periodically flooded, with sediments deposited during these flood events contributing to their formation. Both deltas and floodplains are important features of river systems that are shaped by the balance between erosion and deposition processes.

Answer 7

because of the different effects and the different weather.

Answer 8

its formed by a occulded front
