# Resuspension

Pesticide in the sediment layer is available for resuspension. The amount of pesticide that is removed from the sediment via resuspension is:

                     $$pst\_{rsp,wtr}=\frac{v\_r}{depth}\*pst\_{rchsed}\*TT$$                                    7:4.2.10

where $$pst\_{rsp,wtr}$$ is the amount of pesticide removed via resuspension (mg pst), $$v\_r$$ is the resuspension velocity (m/day), $$depth$$ is the flow depth (m), $$pst\_{rchsed}$$ 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.
