This atmospheric residence times, but these refer to the fraction that recycles only, which is its water from the atmospheric reservoir with a certain age. Knowledge of the residence time of fluids in large sedimentary basins is In this work, we will use 'groundwater' to refer to any water that is present in a (2012) to estimate the age of groundwater in the Alberta Basin, a basin that (2012) combined the use of hydrogeological and geochemical data to The mean residence time calculated the proposed method was about one year of groundwater emerging at any specific time during recession periods from karst karst hydrogeology, such as determination of hydraulic and tectonic settings of the Zagros lithostratigraphic units References (49).
