Sheugh is a Scottish term that refers to a ditch or small trench in the ground. When trying to describe a similar feature, you might use one of the following synonyms: channel, furrow, trench, groove, or gully. These words all describe a depression in the ground of some sort, although they may differ in terms of their size or shape. A channel can be narrow or wide and may refer to a body of water or an artificial conduit. A furrow is a narrow trench made by a plow, while a trench may refer to a long, deep ditch or excavation. A groove is a narrow depression or shallow trench, and a gully is a deep and steep-sided trench, often created by running water.
