FLASH FLOOD

Flash flood is defined as a sudden flow of current rates and area. The area prone, flash floods in the cities for example Kuala Lumpur, Johor Bahru and Kuala Lumpur. Various factors that cause flash floods occur and largely due to human activities

Urbanization causes many modernized areas. Lowland areas have been reclaimed by taking land from the hills. There are also children who filled up the river to serve building. The site activities such as this are the root cause of flooding. In the past, creeks and valleys made ​​the water flow; now the area has been filled with soil. When it rains, water will flow from the hills to the lower area and then stagnate. Eventually the water will increase and flash floods will occur.

Besides, river erosion also causes flash flooding. River erosion that often occurs due to two factors: erosion of naturally occurring human and domestic waste. Natural factors, the place when it rains heavily, the water flowed freely and eroded river banks. Finally land banks will collapse and form sediment on the river bottom. Next the river will be less. Same also with human activities like throwing domestic waste such as garbage and industrial waste into the river caused river siltation and water flow is blocked. When the heavy rain, the river has become shallow due to erosion or pollution of natural cannot cope with a lot of rain water. Eventually the water will spill over the banks and the flood is going to happen.

Basically, flash floods occurred due to human greed in the pursuit of worldly wealth alone. Therefore, as an endive we should keep our activities so that this will not happen again in the future. The governments should also play an important role in preventing these incidents so that people can live in peace and harmony as well as prevent the destruction of property and possessions.
