Suspended sediment routing through a small on-stream reservoir based on particle properties

Abstract Purpose A novel concept of suspended sediment (SS) routing through a small reservoir is proposed that relies on the particle properties in inflow. Methods The SS described following single continuous stirred tank reactor with only one model parameter, decay coefficient. This parameter linked to settling velocity and water flow velocity. Hence, does not require direct calibration recorded data. was tested Warsaw, Poland, seven storm events. Suspended samples at inflow outflow were taken manually during passage flood flows irregular intervals. performance method verified approach when estimated directly from Results calculated based about 10 times higher than corresponding optimized there need introduce correction factor accurately predict effluent SS. led high for all events (Nash-Sutcliffe = 0.672 average). Conclusions (i) has been proven simulate outlet. (ii) Thus, can be velocity, but must applied. (iii) Our findings acknowledge difficulties describing reservoirs indicate lack knowledge functioning these reservoirs.
