Public ISBD Titre de série : US geological Survey Water Supply Paper, 2297 Titre : Estimation of recharge rates to the sand and gravel aquifer using environmental tritium, Nantucket Island, Massachusetts Type de document : texte imprimé Auteurs : Knott, F. F. ; Olimpio, J. C. Mention d'édition : U.S. Geological Survey, Federal Center Editeur : U.S. Geological Survey, Federal Center Année de publication : 1986 ISBN/ISSN/EAN : CI-05045 Note générale : Estimation of the average annual rate of groundwater recharge to sand gravel aquifers using elevated tritium concentration in ground water is an alternative to traditional steady-state and water-balance recharge-rate methods. The concept of the tritium tracer method is that the average annual rate of ground-water recharge over a period of time can be calculated from the depth of the peak tritium concentration in the aquifer... Then the report shows that the accuracy of the tritium method is dependent on two key farctors : the accuracy of the affective-porosity data, and the sampling interval used at the site. For some site the need for recharge-rate data may require a determination as statistically accurate as that wich can be provided by the tritium methods.
