drainage channels
Runoff escape routes
Drainage channels are grooves, ditches, or conduits designed to carry water away from an area.
They may be natural formations or engineered structures—from roadside ditches to elaborate urban stormwater systems.
The term appears in contexts ranging from agriculture to civil engineering: The drainage channels kept the field from flooding.
