CE-093 Rational Method Hydrological Calculations

PDH Star | T / F: (833) PDH STAR (734 7827) | E: CE 093 rational method hydrological calculations Instructor: Harlan Bengtson, PhD, Course ID: CE 093 PDH Hours: 3 PDH 1 Rational Method Hydrological Calculations with Excel Harlan H. Bengtson, PhD, COURSE CONTENT 1. Introduction calculation of peak storm water runoff rate from a drainage area is often done with the Rational Method equation (Q = CiA). Calculations with the Rational Method equation often involve determination of the design rainfall intensity and the time of concentration of the watershed as well.
