We sampled sediments in an agricultural catchment in Reporoa, New Zealand, before and after a scouring flood event. The tributary was chosen for its low slope and predominantly single land use (intensive dairying). This work suggests that despite changes in sediment composition due to flood events, EPC0 is a useful reflection of daytime baseflow-DRP concentrations at sites along a stream network. These data also inform our understanding of the influence of sediment on delaying farm and catchment efforts to decrease in-stream DRP concentrations.
