Sub-Bankfull Flow Frequency versus Magnitude of Flood Events in Outlining Effective Discharges. Case Study: Trotuș River (Romania)

Abstract: Effective discharge, which represents the flow, or range of flows, that transport the most sediment over long term, was determined based on the mean daily flow discharge and mean daily suspended sediment discharge recorded between 1994 and 2014 at four gauging stations along the Trotuș River. This study proposes an efficient method for the estimation of effective discharge based on observed values of the suspended sediment load. By employing this method the suspended sediment load is no longer either under- or… Show more

“…Type II hysteresis loops account for a significant share of the total number of D type floods (25% or 13 flood events), therefore confirming that this type is specific to moderate floods with limited flow discharge, low sediment yield and high SSC [73,75,77]. The prevalence of type I hysteresis loops is in full compliance with recent channel changes observed on Trotuș River, namely the tendency of degradation [33,34].…”
