APPLICATION OF THE NATURALLY-OCCURRING DEUTERIUM ISOTOPE TO TRACING THE CAPILLARY FRINGE
Sidle*, W C. APPLICATION OF THE NATURALLY-OCCURRING DEUTERIUM ISOTOPE TO TRACING THE CAPILLARY FRINGE. Chapter 3, Looney, B.B. and Falta, R.W. (ed.), Vadose Zone Science and Technology Solutions. Battelle Press, Columbus, OH, II:appendices, (2000).
Naturally-occurring deuterium is a useful tracer of subsurface hydrologic processes. A possible application includes the identification of capillary fringes in the vadose zone. Multiple and discontinuous water tables persist in many temperate regions, under various hydrogeologic conditions. It would appear that careful measurements of deuterium can augment more traditional indicators of soil moisture in the unsaturated zone. Possibly then leak detection of barrier systems can be improved.
