Short description: Identifying the different sources of water entering a site such as a wetland, where surface and subsurface water interact, is not always straightforward. This papaer uses a method based on the measurement of conductivity and stable oxygen isotop 18O to give a rapid assessment of the proportions of surface and subsurface water; it may also be possible to use the technique to differentiate a third source, depending on the conditions. The tests were carried out on a meander bend of the Garonne river in south-west France, which contains an interesting case of active paleo-channels. A second site in the Himalayas mountains has also been tested to discriminate between snow and glacier melt.
