Abstract A typical agricultural headwater stream was chosen as the representative to investigate the dynamic characteristics of effective flow for nutrient retention over a longer time scale, based on the change of regional hydrology, from the perspective of coupling the discharge probability density function and nutrient retention efficiency. Through the Monte Carlo simulation for discharge probability density function, the overall level of nutrient retention for the target stream was quantitatively evaluated as well as the most effective flow and the functionally equivalent discharge were calculated, according to the nutrient uptake velocity derived from field tracer experiments. The overall levels of retention capability for NH4+ and PO43- were quite low. The expected values of the retention efficiency of NH4+ and PO43- were 0.0671 (6.71%) and 0.0541 (5.41%), respectively. The most effective flow for NH4+ and PO43- were 0.0051m3/s and 0.0049m3/s, and the functionally equivalent discharge for them were 0.044m3/s and 0.043m3/s, respectively. In view of the fact of low nutrient uptake velocity in the stream, it is necessary to improve the nutrient retention efficiency of the target stream by reconstructing stream morphology and streambed geomorphology.
