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