Two-stage Drainage Ditch
A drainage ditch is a depression in the land created to channel water. Drainage ditches are typically formed around low-lying areas, roadsides or fields proximate to a water body or created to channel water from a more distant water source for the purpose of plant irrigation. The two stage drainage ditch is classified as a 'surface' sustainable drainage system, contrary to a sub-surface system. The two stage drainage ditch is a modification of the land whereby grass benches which serve as floodplains are formed within the land of the watershed of the water system, shown in the diagram to the right. By implementing benches either side of the Body of water, water body, the energy of surface runoff dissipates, sustaining fluvial processes of the channel, thereby improving the water stability and water quality of existing channel. __TOC__ The Environmental Issues Inadequate drainage ditches and water management systems accelerate processes of Water pollution, water contamination, exc ...
