Paved and grassed waterways

Country
Source
WOCAT

An artificial drainage channel constructed along a steep slope to receive run-off from cut-off drains and graded structures and safely drain it towards a natural waterway. The waterway carries excess water to the river, reservoirs or gullies safely without creating erosion. Vegetative waterways can be used in place of stones and for gentler slopes. Paved waterways are suitable in steeper terrains and areas with large amount of stones.
