Bank and ditch

Preliminary

This is a provisional report about a future proposition for specific tags for the following types of ditches and banks:

  • bank and ditch barrier
  • hedge and ditch barrier
  • canal d'abissage
  • fossé bordier
  • talus

We have presently (June 2020) the following tags:

  • barrier=ditch - A man-made ditch or a trench is a long and narrow man-made barrier dug in the ground to prevent access to the other side. No precision about the type of the ditch.
  • military=trench - Is used to map a military trench: an excavation in the ground that is generally deeper than it is wide, dug into the ground as a barrier for military purposes (e.g. trench warfare).
  • natural=earth_bank - Not a man-made feature.
  • natural=valley - Not a man_made feature.
  • natural=cliff - Not a man_made feature.
  • waterway=ditch - A simple narrow artificial waterway used to drain nearby land, to remove storm-water or similar.
  • waterway=drain - Artificial waterways, typically lined with concrete or similar, used to carry superfluous water like storm water or grey-discharge.
  • man_made=embankment - Is used to map an artificial slope or steep incline built for example to provide a level platform on top for a road or railway line or to otherwise shape or stabilize the terrain. For micro-mapped embankments, it is not possible to specify the dimensions (height, width).
  • embankment=yes - Add this tag to a way that is already tagged with a highway=*, railway=* or waterway=* tag.

None of them seem to exactly concern the ditches and banks mentioned above.

Bank and ditch



Bank and ditch or hedge and ditch are earthworks in the landscape. All have a historic interest as being the landmark for present and past administrative boundaries; they were used to limit lands, parish, communes, forests, etc.


They are not designed for drainage even if water can flow in the ditch. 

 They can be found under various names :

  • in English: ditch, bank, bank and ditch, hedge and ditch, dry ditch, earth bank, ditch earthworks, levee, ha-ha
  • in French: fossé, talus, talus-fossé, berme, bourrelet de terre, levée, levée de terre, saut de loup, ha-ha hâ-hâ
  • in Dutch: landweer, Ha-Ha, Aha
  • in German: Ha-Ha, Aha


 Usually, we find one ditch with a parallel bank. Occasionally, we can find one ditch and two banks on either sides, a single bank and a ditch on either sides. Hillsgade Lidar-derived imagery gives an good opportunity to observe their tracks. 



 They have been studied in various articles:

  1. Boundaries in the Landscape – Banks, Ditches and Walls, [1]
  2. 
Section of an early medieval boundary ditch known as the Nico Ditch on Denton golf course 320 m south west of Lodge Farm, [2]
  3. Banks and Ditches on the Northern Malvern Hills, [3]
  4. Pits, Platforms, Banks and Ditches, [4]

Other ditches and barriers with no specific tag

Hedge and ditch

See #Hedges in history, [5]

Canal d'abissage

Used for an artificial waterway designed as a watercourse in a ditch created for this purpose, a ditch called ri d'abissage" or ry d'abissage or fossé d'abissage or bief d'abissage depending on the region, in order to bring it upstream of the meadows to be irrigated. See also [6].

Fossé bordier

Fossé qui délimite d'anciennes parcelles exploitées de manière discontinue depuis au moins deux millénaires en Narbonnaise. Sa présence marque la trace sur le sol de l'appropriation d'un terroir et d'anciennes mises en culture. Ditch which delimits former plots of land which have been exploited discontinuously for at least two millennia in the Narbonnaise region. Its presence marks the trace on the soil of the appropriation of a terroir and old cultivation.

Talus

[To be discussed]

Talus plantés

Are one of the identity elements of the clos-masure. Fencing off the plot of land which includes all the buildings, the high jet trees are planted on land levees 1.5 to 2.5 m wide and 0.6 m to 1.30 m high. In Normandy. See [7]

Limites de centuriations

Centuriation (in Latin centuriatio or, more usually, limitatio, also known as Roman grid, was a method of land measurement used by the Romans. In many cases land divisions based on the survey formed a field system, often referred to in modern times by the same name. It may appear in the form of roads, canals and agricultural plots. Maybe not of interest presently on OSM!
