definition
A 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.(Wikipedia, Ditch, accessed on Sept. 2016)
Co-benefits and impacts
Ditches can be integrated into green verges or the roadside. They look natural but they do need extra space and maintenance. Ditches can be designed to facilitate infiltration or to provide green space.(Urban Green-Blue Grids for sustainable and resilient cities, Ditches, accessed on Sept. 2016)
