Measures such as detention structures and buffer strips are widely used to limit off‐site damage of run‐off from eroding fields. The effectiveness of such measures varies greatly.

Detention structures and buffer strips retain coarse sediment (>~100 μm diameter) but are less effective at retaining fine sediment.
