Social Effects Of Rainwater Floods

Catchment area, river water means the surrounding area flowing. If the four sides are surrounded by mountains, the catchment area is unclear. The edge of the catchment area is composed of high parts like mountain peaks and peaks, and it forms a boundary with the catchment areas of other rivers around these parts. This boundary is called the hydrometer. In other words, one river forms a basin around the top of a mountain or a peak. Watershed, in the case of rainfall, it refers to the surrounding area where water flows into the river, and rainfall in one watershed is collected at the lowest point in the watershed. Most of the area is surrounded by mountainous areas, but the watershed is often unclear on the plain. When it rains, the rainwater

Flooding can have numerous social, economic and environmental effects that can vary depending on the demographics of a population and the economic development of the area. In social effects, the greatest and most obvious effect is death. Floods kills people, because flood water can travel surprisingly quickly, and the weight is very heavy thus people can be easily swept by floods. In a LEDC, Less Economically Developed Country, there are much more deaths occurred than in those MEDC, Initialism of more economically developed countries, because in MEDC, people and governments are better prepared for floods, rescuing services is more faster and well done than LEDC. Secondly, if flood occurs, the sewage pipes are often broken and raw sewage leaks into the floodwater which contaminates the floodwater also the drinking water, which could lead to a spread of waterborne diseases such as cholera. In economic effects, flood is a cumbersome because there are many property damages. Very large and powerful floods can even dislodge buildings from their foundations and move them. Floods can cause extensive damage to infrastructure such as power lines, roads, water pipes and so on. Also bridges often collapses during some floods with high discharge of the river. In the countries where more developed the more damage there are

Bangladesh experiences many tropical cyclones and also the flooding is very often occurred in that region, half the country is less than 6 meters above the sea level. Thus, human causes of global warming that causes snowmelt will affect the flooding in Bangladesh, building on the floodplains and cutting down trees both increase the effects of flooding. Bangladesh is LEDC, Less Economically Developed Country, 80% of Bangladesh is floodplain, and is prone to flooding due to being located on the Ganges Delta and the many distributaries flowing into the Bay of Bengal. Coastal flooding, combined with the bursting of river banks is common, and severely affects the landscape and society of Bangladesh. The advantages to living in Bangladesh are that the flat floodplains of the delta are very fertile for crops to grow healthy, and the area can also be used for shrimp farming. On the other hand, the low-lying islands are very vulnerable and flood easily, which is difficult to protect, and there are poor communications, since Bangladesh is LEDC, many locals do not own telephone or television, which is difficult to warn flooding early in hand. For the reasons mentioned above, the Flood Action Plan is funded by the World Bank that is implemented now, it funds projects to monitor flood levels and construct flood banks.
