Document Summary
Most cases: we can predict where flooding is likely to occur from location of floodplain and from mapping extent of recent floods. Determining probability of particular event occurring at particular location within particular time span. Essential for hazard prediction although 10 year flood may occur on average only once every 10 years, it is possible to have several floods of this magnitude in any one year. Forecasting and prediction it is sometimes possible to accurately predict when certain natural events will occur. Hydrologists usually can predict when river will reach particular flood stage or water level it means we should be prepared for the event.
