Subsurface flow from snowmelt traced by tritium

Abstract: An explanation is offered of the apparent discrepancy between the small velocities of subsurface flow and the watershed response. Environmental tritium in the hydrological cycle provided evidence for a new insight into the runoff mechanis m. By this concept the quick reaction of outflow to a massive groundwater recharge is brought to agreement with the long residence time of the infiltrated water. ROLE OF SUBSURFACE FLOW IN THE RUNOFF The proportion of subsurface flow in the total discharge has been frequently… Show more

“…Over the past decades, conventional tracers used in experimental hydrology have considerably improved our understanding of time-and geographic sources of streamwater (Hooper et al, 1990;Martinec, 1975;Sklash and Farvolden, 1979). However, these approaches also have well-known limitations (e.g.…”

“…Countless studies have shown that the hydrologic response of headwater catchments can be much faster (orders of magnitude) than the mean transit time of water (e.g., Martinec, 1975;Seeger and Weiler, 2014). Or, in other words, during a rainfall or snowmelt event stream discharge responds immediately, while the average age of stream water itself can be years or decades old (Kirchner, 2003).…”

“…Les traceurs isotopiques stables (deuterium, tritium et 0 18 ) ont été utilisés par plusieurs auteurs (DINCER et al, 1970 ;MARTINEC, 1975 ;PEARCE étal., 1986 ;MAULÉ et STEIN, 1990) afin de calculer la contribution relative de l'eau stockée dans le bassin versant entre les averses (vieille eau) et de l'eau de pluie ou de fonte (jeune eau) au débit total du cours d'eau. La plupart de ces études ont indiqué que la « vieille eau » domine le cours d'eau lors de fortes décharges.…”
