Description
Summary:This research intends to map floods in the Juana Watershed. However, the flood disaster in the Seluna River system started when the flood land was developed for residential areas, agriculture as well as industry, so the damage potency due to the flood will increase. Along with the increasing of population number and density, the social impact that is more serious than flood will follow – like the threat of loss of life. The impact is the management of flood risk becomes more complex and expensive. The methodology for flood mapping consists of the assessment of flood index, vulnerability, and capacity. Determination of flood hazard index is carried out based on the classification of inundation depth. The process is carried out by using spatial calculation, so it can produce the risk map and grid value that can be used in arranging the explanation of the risk map. The result of flood mapping is hoped to be able to support the model development of flood risk management towards the area layout.
