FLOODSFlood is a natural phenomenon which is the water from all the water sources on the earth overflaw on resident living places. Flood is a dangerous disaster for human living. Sometimes, flood caused by the human activites. Flood happens in all part of the world. How is the process of flood?

Flooding may result from the volume of water within a body of water such as a river, lake, or ocean. Raining in high intensity and continually along day is the major case of flooding cause. Regions that have two seasons (near the equator) tend to have raining longer than regions which have four seasons (about six months).

Besides, soil density also influences the incident of flood. Water from the rain can’t be absorbed perfectly by the soil. While this happens, the depth of water above the surface will higher and higher. Then it drowns the surrounding area: office, houses, school, rice field, etc. Flood like this often occur in urban areas. Floods can be caused by two things, can result from human activity or natural phenomena result from the extreme form of prolonged rain. The main cause of most of the flooding is the excessive rainfall. The rain may occur seasonally-region covering large areas, or from local storm producing rainfall of high intensity. Most floods are caused by the processes of the atmosphere or the ocean and high speed air currents. Melting snow (happens in the 4-seasons State) is another major cause of flooding. On the other hand, human activities can also be a potential disaster such as floods and forest logging that is getting crowded. For the classically logging, though not exactly true, the main suspect of flooding are farmers, who cut down forests in upstream watershed. Settlement and compacting the soil does not give a chance of rain water to seep into the ground. Most water, then flow on the ground. Moreover, the river is supported by an increasingly shallow and narrow river crowded with inhabitants, and the blockage of water upstream area. Then came the flood. In fact, once the flood happens in an area, the next flood will be easier again. Because the pore surface covered with mud so that the soil water is not able to penetrate. Floods can cause some losses, both moral and material. As property in the form of electronic devices can not be used anymore because of submerged and other household equipment that is damaged. Floods that are not too big do not give too bad impact to human lives. But if the flood disaster in a large scale, it can also impact on human life. Year to year, human always make development that cover the soil without green places in any urban areas. Human only want to get much adventages from that without think about how the effect from their do. Factory also has contribution in making flood. Factory and human littering the river that obstruct water circulation.

So, what we can do ? We must cooperate with govermant in Increasing the green areas, make laws of illegal logging and changing people's behavior to not make the river as a giant trash. Participation of all elements of society must be organized and coordinated in order to run effectively. A community organization should be formed to take early action and organize public participation in flood mitigation.
