Scientific methods are very important in predicting the behaviour of the earth's natural processes. There are lots of natural destructive phenomena that would have been averted should there have been ways of accurate prediction of their occurrences. Earthquakes, hurricanes, typhoons, and many other natural calamities have wreaked havoc and destroyed lives and property.


To understand more on the subject at hand, we first define what is a storm and a hydrograph. According to Wikipedia, a storm is any disturbed state of an astronomical body's atmosphere, especially affecting its surface, and strongly implying severe weather. It may be marked by strong wind, thunder and lightning (a thunderstorm), heavy precipitation, such as ice or wind transporting some substance through the atmosphere.1 Meanwhile a hydrograph is defined as "a representation of flow for a particular stream and is used to evaluate the watershed runoff volumes and the peak flow rates from a single storm or set of storms. This information is then used in the design of flood control facilities."2 A storm obviously has a fundamental effect on the course of rivers and other bodies of water and is part of the process known as the water cycle. The water cycle "..consists of four distinct stages: storage, evaporation, precipitation, and runoff. Water may be stored temporarily in the ground; in oceans, lakes, and rivers; and in ice caps and glaciers. ...
