When a river plunges vertically over a rock face, the result is a waterfall. Flood plains are often more attractive to developers because they tend to be flat and therefore easy to build on and close to other amenities such as transport and utilities networks. A stream with a steep gradient will tend to downcut faster than it causes lateral erosion resulting in a deep narrow channel with little or no floodplain at all. When the arch collapses, it leaves the headland on one side and a stack (a tall column of rock) on the other. It is a very fertile area due to the rich alluvium deposited by floodwaters. Floodplains are often agricultural land as the area is very fertile because its made up of alluvium (deposited silt from a river flood).

Natural levees are ridges along river banks that form from rapid deposition from overbank flow. The force of the water erodes and undercuts the river bank on the outside of the bend where water flow has most energy due to decreased friction. This happens both laterally (as a stream flows across the earth) and vertically (as the stream drops in a waterfall). . Explain The Formation Of A Flood Plain: Floodplains Formation, Estuaries are commonly described as semi-enclosed bodies of water situated at the interface between land and ocean where sea water is measurably diluted by the inflow of freshwater (Hobbie 2000). A delta forms when a stream deposits sediment in another body of water. Floods are often caused by heavy rainfall rapid snowmelt or a storm surge from a tropical cyclone or tsunami in coastal areas. This causes the ground to rise and form a thick layer of soil. Estuaries are greatly influenced by tidal action. In New Zealand, there are around 300 estuaries. 2009).
