This course discusses two common methods of storm water runoff and detention, the Rational (Modified Rational) and SCS Methods. In depth discussion of input variables along with limitations for each method will allow the student to more accurately model detention for a particular site, while maintaining practical engineering practices. The accuracy of each method is evaluated by using examples of different method calculations and comparisons to measured flows.

This course is relevant for consulting engineers and municipal engineers involved in the planning, design, and/or review of storm water drainage and detention systems.
