Hi Eugene Thanks for your summary! [^1] I'm in favour of the proposed definitions and would welcome if the clarifications regarding size you made here [^2] were included in the definitions, like for example (*additions*, ~~deletions~~):
canal - Large man-made open flow (free flow vs pipe flow) waterways used to carry useful water for transportation, hydro-power generation, irrigation or land drainage purposes. Consider using waterway=ditch for small*er* ~~irrigation or land drainage~~ channels *that directly distribute water to or collect it form the land*. Consider using waterway=drain for small usually lined superflous liquid drainage channels. ditch - Small artificial free flow waterways *used to directly distribute water to dry land (for irrigation) or collect water from wet land (for drainage)* ~~used for irrigating dry land or draining wet land~~. Irrigation ditches can be lined or unlined, drainage ditches are usually unlined to let water soak through the land into them. Ditches may have short lined segments at waterway turning points or intersections with roads or paths to prevent erosion. Consider using waterway=canal for large*r* ~~irrigation or land drainage~~ channels *that convey water from or to ditches*. Consider using waterway=drain for usually lined superflous liquid drainage channels.
