                                                        Flooding

       Flooding is a natural phenomenon that is common in a lot of areas drained by streams. In a simple flooding can be defined as the presence of water in a vast region that covers the area of the earth's surface. In a broad sense, flooding can be interpreted as a part of the hydrological cycle, namely in the water on the earth's surface are moving into the sea. In the hydrologic cycle we can see that the volume of water flowing on the surface of the Earth predominantly determined by the level of rainfall, and the rate of water infiltration into the soil.
       Rainwater up in the Earth's surface and flows on the surface of the Earth, moving towards the sea to form the ravines. Ravines is started in the area of the highest in the region, could mountainous areas, mountains or hills, and ended up on the beach when the water flows into the sea. Simply put, a segment of the river flow can be differentiated into regions upstream, midstream, and downstream. In the upstream area, usually located in mountainous areas, mountains or hills. In the river channel many large rocks (boulders) from the ruins of the cliff, and the flow of river water flowing in between the stones tersebut.Terjadi erosion in the vertical direction by the dominant water flow sungai.Di central area, generally an area of the foot mountains, foothills, or the foot of the hill. The erosion in the horizontal direction, erodes the host rock. The basic flow of the river widened, and at the bottom there is a river channel of the river sediment grain size of coarse. If the water flow increases, the flow of water can rise and river sediment cover in the groove, but the water does not pass through the river bank of the river and out of the river channel. In the downstream area, generally is lying areas. River channel width and can be very wide with riverbanks relatively very low compared to the width of the groove. On the left and right groove plains regularly there will be inundated by water overflowing rivers, and became known as floodplains.
       From the above explanation can be concluded that flooding is an event that occurs when the flow of excess water to soak the land. Floods can also occur in rivers, when flow exceeds the capacity of waterways, particularly in the gutter of the river. As a result, able to soak and damaging roads, bridges, cars, buildings, sewer systems, and canals. Estimated loss of life and property is another impact of flooding.
