Flooding is one of the most common natural disasters in both developed and developing countries, and it is occasionally of devastating impact, as the floods in China in 1959 and Bangladesh in 1974 and the tsunami in Southeast Asia in December 2004 show. It is also the predominate cause of death associated with the natural disasters, with most of the death are caused by drowning.
In fact, causes of flooding can be divided into two, that are natural factor and human factors. However, we can only prevent human factor from both of the factors. The main causes of the flooding is when rainfall continuously for a few days. The ground will become so wet until no more water can trickle through the earth. So, the water runs into the river, causing the water level in the river rise quickly until the river cannot cope with the water level.

During the rainy season, the garbage we thrown become the one which obstruct the river channel and affect the water flow in the river. It will cause flood because it will cause the water to spread out from the river when the trashes clogged

Standing water and slow-moving water caused by the flood water or heavy rainfall can become the breeding sites for mosquitoes. This situation enhances the potential for exposure of the disaster-affected population to the infections such as dengue, malaria. The collection of stagnant water due to the blocking of drains, especially in urban settings, can also be associated with increases in transmission. The 1982 El Niño event, for example, caused extensive flooding in several countries in Latin America and apparently sharp increases in
