Ditches are waterbodies that have been created by people, mainly to drain the land. What is a ditch? Unlike streams, ditches are usually straight, follow linear field boundaries – often turning at right angles – and show little relationship with natural landscape contours.

These are shallow excavations that run parallel to the road. Their main function is to divert water to the principal drain and thus prevent excess water from running on to the road surface.
This type of ditch runs beneath the road or highway. It needs a system of subterranean tubes that lead to a principal collector.
In this system a tube traverses a small slope, which takes the water away from the road through tubing.
It functions like the gutter on a building’s roof. A system of tubes collects the excess water and carries it to a sewage system. The advantage of this system is that it is cheaper to install than most others.
All the previous systems are basically built with concrete and cement. But there is another kind of ditch that is covered with grass. These are the green ditches. They are excavated with a base of more than a meter and a half and on gentle slopes. Their design is optimized to collect and treat the volume of quality water, and they should generate s...
Jan 10, 2022 · What is a ditch? Ditches are deep and narrow channels that convey stormwater runoff. Ditches typically have steeper sides than swales and are built to convey large volumes of water quickly away from a site without creating erosion.
Often the best surface drainage is obtained by a ditch following low swales. To improve alignment, ditches may cut through minor rises in topography. curves.
2 days ago · Although a swale and drainage ditch may look the same, a ditch is designed solely for conveying drainage water, with no water quality treatment intended. A swale, on the other hand, is typically a regulated and engineered SCM that is credited for treating and conveying stormwater.
