Flood

floods A flood is an over flow of water which covers land which is usally dry.There are 2 types of floods :inland and coastal.Most inland floods happen when there has been heavy rain or when a lot of snow melts. the water swells rivers and creeks and makes them overflow their banks. Coastal floods are caused by high tides, a rise in sea level, storm waves and on-shore winds.
