Pesticide in the sediment layer is available for resuspension. The amount of pesticide that is removed from the sediment via resuspension is:
pstrsp,wtr​=depthvr​​∗pstrchsed​∗TT 7:4.2.10
where pstrsp,wtr​ is the amount of pesticide removed via resuspension (mg pst), vr​ is the resuspension velocity (m/day), depth is the flow depth (m), pstrchsed​ is the amount of pesticide in the sediment (mg pst), and TT is the flow travel time (days). Pesticide removed from the sediment layer by resuspension is added to the water layer.
