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.
