The build‐up of soil and sediment on the up‐slope side of a wall or fenceline running across a hillside. Because the wall or fence serves to halt the down‐slope movement of material, the accumulation may eventually bury it. Such a build‐up is further exaggerated by the fact that on the down‐slope side of the developing lynchet there is likely to be a loss of material from the soil profile. This is known as the negative lynchet. Ultimately, the effect of lyncheting is to create a series of flat steps or cultivation terraces up the side of a hill.
