Carbon 13 of TDIC to quantify the role of the unsaturated zone: the example of the Vaucluse karst systems (Southeastern France)
Abstract:
The total dissolved inorganic carbon (TDIC) and C-13(TDIC) have been used as chemical and isotopic tracers to evaluate the contribution of different water components discharging at the Fontaine de Vaucluse karst spring near Avignon. At the same time they have been used to separate its flood hydrograph. Waters flowing from unsaturated zone (UZ) and saturated zone (SZ) show similar concentration in TDIC. In UZ and SZ water rock interactions do not obey to the same kinetic. The mixing rate between water coming from the UZ characterised by a short residence time and water from the SZ with a longer residence time has been evaluated in the spring discharge. In a hydrodynamic system, which is rather complex as it is open to the soil CO2 in UZ and closed to the same CO2 in the SZ, C-13(TDIC) has excellent characteristics as an environmental tracer. In order to better describe the inwardness of mass movements within the aquifer, the apparent contrasting information obtained using two different isotopes (O-18 of water molecules and C-13 of TDIC) must be combined. O-18 informs whether the hydrodynamic system acts as piston flow (PF) or follows a well mixing model (WMM). Conversely, C-13 gives more complete information on the UZ contributes to the total discharge. (C) 2003 Elsevier B.V. All rights reserved
