rainfall-runoff model such as the HEC-1 model and they are an actual storm event and a design storm event. Discuss the difference between the two and discuss when you would
use one over the other. An actual storm is just that. It lasts for the time it will last, and it releases
the amount of rainfall that it will. A design storm is based on actual storm data for a specific area, but it does not represent a specific event.
Rather, design storms "are precipitation patterns used for hydrologic modeling" and are "based on historical precipitation data for the area of interest" (Maidment, 1996).
Maidment (1996) used a design storm calculated by the TxDOT IDF curve equation for a county that Maidment (1996) wished to model.
In the design storm, the researcher calculates incremental depth through the use of distinct time intervals, using this equation: Where b, d
and e are coefficients; td is time increment and rainfall is measured in inches (Maidment, 1996). When using design storm, the researcher can create a design storm of any
frequency or duration for use in a hydrological model. This is not the case when using an actual storm. Natural storms are
highly variable in length of duration and volume of discharge (Chapter 5, 2004) and can even vary between locations during a single event. The design storm can be "customized"
to duration and volume, to the point of expectation of a matching actual storm over time. The five-year design storm is commonly used; the 100-year design storm typically is
