Rational Method Step 5 Calculating Time Of Concentration

B. Stormwater Calculations - NC

The peak flow is often calculated using the Rational Method. Calculating the peak flow is an important design step in designing a flow-based device such as a level spreader-filter strip. It is also important to meet SA waters requirements per 15A NCAC 02H .1019. The composite runoff coefficient, C, reflects the runoff potential of the drainage ...
