definitionA ditch is usually defined as a small to moderate depression created to channel water. A ditch can be used for drainage, e.g. to drain water from low-lying areas, alongside roadways or fields, or to channel water from a more distant source for plant irrigation. A trench is a long narrow ditch. Ditches are commonly seen around farmland especially in areas that have required drainage such as low land areas. Ditches can also carry off excess water or sewage.
