            \nOn a piece of paper, draw your village\/town map roughly. Locate your home, school and playground on the map. Then draw the rivers\/stream\/lake and road, located nearest to your village\/town. Answer the questions listed below.<\/p>\n

            Question 1.
            \nWhich areas and roads would be mostly affected by flood?
            \nAnswer:<\/p>\n

              \n
            1. Floods can happen on flat or low-lying areas when water is supplied by rainfall or snowmelt more rapidly than it can either infiltrate or run off.<\/li>\n
            2. The excess accumulates in place, sometimes to hazardous depths.<\/li>\n
            3. Surface soil can become saturated, which effectively stops infiltration, where the water table is shallow, such as a floodplain, or from intense rain from one or a series of storms.<\/li>\n
            4. Infiltration also is slow to negligible through frozen ground, rock, concrete.<\/li>\n
            5. Areas near water bodies such as lake, river, etc. are also affected by flood.<\/li>\n<\/ol>\n

              2. A study of non physical mitigation, i.e. to establish some alternatives of evacuation routes to some temporary shelters is to be conducted well in advance.<\/li>\n
