On the role of the runoff coefficient in the mapping of rainfall to flood return periods
runoff coefficient rainfall flood return periods
2009/7/22
While the correspondence of rainfall return period TP and flood return period TQ is at the heart of the design storm procedure, their relationship is still poorly understood. The purpose of this pape...
