Flow duration and bankfull
WebBankfull is a concept that is intimately tied to the annual flood series through the well-accepted tenet that bankfull discharge occurs at approximately the 1.5-year recurrence interval on the annual series. Thus, due to this association the annual series provides a useful diagnostic tool for helping to identify the bankfull elevation in the field. WebThe flow duration curve is employed to quantify the effect of these processes, as well as to account for flow variability. Our model captures the spatiotemporal evolution of bankfull …
