afvandingskanaler
Afvandingskanaler are engineered channels designed to remove excess water from land to prevent waterlogging, crop damage, or flooding. They form part of drainage systems that move surface and subsurface water to natural outlets such as rivers or lakes, or to pumping stations. They can be open channels (ditches) or closed conduits (pipes).
In practice, drainage networks consist of main or primary afvandingskanaler that carry water from large areas,
Design considerations include hydraulic capacity, sediment transport and deposition, erosion protection, lining or stabilization, maintenance access,
Afvandingskanaler are used in agriculture, urban drainage, and coastal or flood-prone regions to manage water levels,
