Preliminary investigation to estimate soil NAPL retention using parametric pedotransfer functions

摘要

Organic liquid retention of soils is a primary input variable for modelling the nonaqueous phase liquid transport and behaviour in the subsurface. In environmental and soil physical practice, it is mainly determined by scaling based on the water retention of soils or with charts of average empirical values of organic liquid retention or the fitting parameters of hydraulic functions. Predicting the fitting parameters of organic liquidudretention curves with pedotransfer functions might be a promising alternative method, but this topic has only been researched to a limited extent. The investigations gave promising results for the possibility to estimate soil nonaqueous phase liquid retention with parametric pedotransfer functions.
