This geology image could be re-created using vector graphics as an SVG file. This has several advantages; see Commons:Media for cleanup for more information. If an SVG form of this image is available, please upload it and afterwards replace this template with {{vector version available|new image name}}.


It is recommended to name the SVG file “Aquifère Darcy échanges flux.svg”—then the template Vector version available (or Vva) does not need the new image name parameter.
This geology image was uploaded in the JPEG format even though it consists of non-photographic data. This information could be stored more efficiently or accurately in the PNG or SVG format. If possible, please upload a PNG or SVG version of this image without compression artifacts, derived from a non-JPEG source (or with existing artifacts removed). After doing so, please tag the JPEG version with {{Superseded|NewImage.ext}} and remove this tag. This tag should not be applied to photographs or scans. If this image is a diagram or other image suitable for vectorisation, please tag this image with {{Convert to SVG}} instead of {{BadJPEG}}. If not suitable for vectorisation, use {{Convert to PNG}}. For more information, see {{BadJPEG}}.

Summary edit

Description
Français : Exemples de situation de déséquilibre par rapport à l'équilibre piézométrique.

Situation A : le niveau du cours d'eau est plus haut que celui de la nappe. Un flux d'eau (avec transfert éventuel de calories, de frigories, de sels, de polluants, de propagules viraux ou bactériens..) s'établit de la rivière vers la nappe (ou vers des compartiments sous-fluviaux le cas échéant), par exemple suite à une crue, jusqu'à ce que l'équilibre se rétablisse, ou que l'on passe à la situation inverse :

Situation B : le niveau de la rivière est plus bas que celui de la nappe (à l'étiage par exemple). Dans ce cas, c'est la nappe qui va alimenter le cours d'eau, en lui apportant le cas échéant ses calories ou frigories ou d'éventuels polluants (si la nappe est polluée) ou que les sédiments le sont. La loi de Darcy et d'autres permettent de modéliser ces deux types de flux et échanges.
English: Examples of imbalance relative to the piezometric balance.

A : the level of the river is higher than that of the web. A flox of water (with possible transfer of calories, cold water, salts, pollutants, viral or bacterial propagules ..) occurs from the river to the underground water (for example due to a flood), until the balance recovers, or we go to the opposite situation (B):

B: the level of the river is lower than that of the level of underground water (at low water period, for example). In this case, ther is a flow from underground water to the stream, bringing in it heat or cold or potential contaminants (if the water or sediments are polluted) . Darcy's law and others allow to model these two types of flows and exchanges.
