ditch
Let an agent explain ditches and their kinds and functions, support designing, digging and maintaining ditches within regulations, describe their ecological and historical roles, and support land and water management questions.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain ditches and their kinds and functions, support designing, digging and maintaining ditches within regulations, describe their ecological and historical roles, and support land and water management questions.
A long narrow excavation in the ground, usually open, dug to drain or carry water, mark boundaries, defend a site or serve mining and construction, including field and roadside drainage ditches, irrigation ditches, percolation trenches and french drains, historical mining water channels, dikes with ditches, and channels made by beavers; ditches are simple but important water management and landscape features with ecological value and maintenance needs.
What it is for: Excavated channels for water and boundaries.
It can be explain kinds and functions; support design and maintenance; describe ecological and historical roles; support management questions.

What it looks like
Long open channels along fields, roads and boundaries.
How it is recognised
Narrow excavation carrying or draining water
Drainage, irrigation, boundary, defensive, mining ditches
A canal is navigable; a moat surrounds a fortification; a trench may be for cables or warfare
