it is especially difficult where I am, because the irrigation ditiches cascade
from on set of fields to the next, sometimes are concrete, sometimes dirt;
sometimes “natural”, sometimes man-made; they all flow like batter in a waffle
iron.
“drains” that take away excess water and runoff eventually lead to another set
of fields, before being dumped back in the river (only to begin the cycle again
500m later).
the idea of ditches and drains seem to be an attempt to define “channel” with a
preset type, construction material, and usage - when it is very vague in some
countries.
