Title Screening Model for Nonaqueous Phase Liquid Transport in the Vadose Zone Using Green-Ampt and Kinematic Wave Theory.
Publication Date Jan 1994
Media Count 14p
Personal Author J. W. Weaver R. J. Charbeneau B. K. Lien
Abstract In the paper, a screening model for flow a nonaqueous phase liquid (NAPL) and associated chemical transport in the vadose zone is developed. The model is based on kinematic approximation of the governing equations for both the NAPL and a partitionable che ...
