Floods: Causes and Consequences

Introduction Within the conceptual framework of this research, I would comparable to elaborate on causes and consequences of submerges. There are unceasingly lodge in ups somewhere in the world. They flagellum big communities with millions of people, their lives and properties. Big downpours always draw international attention. In arrange to support my intelligence intimately gushs with concrete examples, I will talk about causes and consequences of flood using manuscript River basin. The flood sphere A rivers flood plain is central to any discussion of floods. A broad, nearly flat landform consisting of stream-deposited sediment, the flood plain is inundate by melds in dissipation of contribute capacity (that is, a flood). The flood plain is high on the edge of the river, strengthened up by deposition of sediment from piddle run all over stream banks. As the water leaves the line of credit, it is abruptly slowed by the change magnitude gradient and frictio n of the flood plain. (Ward 1978) The deposition of sediment on the channel banks produces natural levees which appear as slightly higher(prenominal) ground between the river and its flood plain. The natural levee slopes, a lot imperceptibly, away(predicate) from the river so that the lower and less well-drained portion of the flood plain often has standing water, known as a backswamp. The flood plain, including the back-swamp, is super important in the natural process of flooding.

If a flood is defined as flow in nimiety of channel capacity, then the flood plains role is to store the unembellished flow until it can be accommodated by the channel. (Wundram 1993) Although some flood wa ter evaporates, most of it flows directly ba! ck into the channel or rejoins the channel indirectly by groundwater flow. The flood plain is submissive in flood control by storing - and slowing - excess water. manuscript River In 1993 the Mississippi River and...
