Modelling two-phase transport of 3H/3He
conference paper
Degassing of groundwater by excess denitrification of agricultural pollution complicates the interpretation of 3H/3He data and hinders the estimation of travel times in nitrate pollution studies. In this study we used a two-phase flow and transport model (STOMP) to evaluate the method presented by Visser (2007a) to interpret degassed 3H/ 3He data using the total dissolved gas pressure to estimate the depth of degassing. We conclude that the method performs well below the depth of degassing. Copyright © 2008 IAHS Press.
