The thickness of soil cover varies in accordance with the protection needed against infiltration and intrusion into the landfill. In general, the following guide can be used: Municipal landfill caps: 12 to 24 in. Residual landfill caps: 18 to 36 in. ... a high-strength, high-modulus, low-creep geotextile or geogrid is necessary to prevent localized, abrupt depressions in the cap system. Such depression would create a "bathtub" effect allowing water to constantly remain in contact with the geomembrane.  3, record 1, English, - bathtub%20effect

Disadvantages are that the boreholes need to be carefully constructed to avoid filling with water (the bathtub effect) should there be leakage through the cover. Retrieval of wastes would be difficult.  2, record 1, English, - bathtub%20effect

The closed facility ... was experiencing trench overflow, sometimes called the "bath-tub" effect. The glacial till in which the trenches were dug had very low permeability and was therefore initially thought to be good material for preventing waterborne release of nuclides. However, it was difficult to construct the covers over the trenches to have and maintain permeabilities as low as the native soil. Consequently, water percolated through the covers, collected in the trenches and eventually overflowed, at or near the surface, carrying radionuclides with it.  2, record 1, English, - bathtub%20effect

The reason much of the lab's effort is devoted to CANDU maintenance ... is that power reactors are subject to the "bathtub effect". They need more repairs and maintenance for the first year or so of their lives - the top of the bathtub - until all systems and components are working smoothly. Then there are many years of relatively trouble-free operation - the bottom of the bathtub - until aging imposes the need for more repairs ....  1, record 2, English, - bathtub%20effect

Phénomène de courbe en baignoire. (...) Selon [M. Bummel] (...), la raison pour laquelle l'entretien des réacteurs CANDU représente une grande partie des activités du laboratoire est que les besoins d'entretien des réacteurs varient suivant une courbe en baignoire. (...) au cours de la première année d'exploitation des réacteurs, des travaux de réparation et d'entretien plus fréquents sont nécessaires jusqu'à ce que les systèmes et composants fonctionnent normalement, - il s'agit de la partie supérieure de la courbe en baignoire. Puis, pendant un grand nombre d'années, l'exploitation est relativement sans problèmes - la partie inférieure de la courbe en question - , jusqu'à ce que le vieillissement donne lieu à une nouvelle augmentation des besoins d'entretien.  1, record 2, French, - ph%C3%A9nom%C3%A8ne%20de%20courbe%20en%20baignoire
