Drainage systems ... The major channels are generally open drains, or ditches, but on each farm closed, or covered, drains are used. Open drains are relatively inexpensive to install, and can carry larger amounts of water. However, they are rarely used for on-farm drainage because of the large amount of land that would be removed from cultivation and because of the difficulties of conducting farming operations between closely spaced open drains.  3, record 1, English, - drainage%20ditch

Le drainage par fossés ouverts permet l'évacuation en surface des eaux; il suppose le creusement de rigoles et de fossés à pente régulière et de section croissante; malheureusement, cet assainissement suppose une topographie convenable des parcelles, gêne la circulation des machines et provoque une perte de terrain parfois importante.  5, record 1, French, - tranch%C3%A9e%20de%20drainage

Figure 6.1 illustrates a typical open disposal trench at the Barnwell facility. The trench floor is sloped slightly and covered with a layer of sand to facilitate collection of percolating water in a french drain. A number of pipes allow any water that may collect in the french drain to be removed and analyzed. Presently waste, primarily in boxes, drums and cask liners, is stacked neatly in the trench, starting at the high end and progressing toward the low end. High specific activity waste is usually placed at the bottom of the trench. A separate narrower shielded trench is used at Barnwell for waste that has very high dose rates at the package surface. As the level of the waste reaches the design level, 2 m below grade, a layer of dry soil is added and allowed to filter down between the waste containers. When a trench is filled, it is covered with a cap of at least 0.6 m of compacted native clay, followed by at least 0.9 m of soil.  2, record 2, English, - open%20storage%20trench
