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.
