Engineering hydrologists sometimes wish to assign a return period to the mean annual hydrologic event. The value of the mean annual event is usually the arithmetic average of annual series of data, such as annual flood flows, annual low flows, etc. This paper presents Tx values for some commonly used PDs in a generalized fashion.
