Abstract

ABSTRACT:In this paper a twophase / threecomponent model concept for simulating interactionprocesses of fresh water, salt water, and methane in coastal aquifers is presented. The numericalalgorithm which is part of the simulator MUFTEUG is briefly explained. If methane occursin very low concentrations and builds no gas phase, the model concept is simplified to onephase/ three component. For this case a reasonable agreement of computations and measurements wasobtained in the range of available data. The simulations showed that certain concentration profilescan be caused by hydraulic conditions and not only by reaction processes as supposed before. Ifmethane occurs as a gas phase, it has a significant influence on the results.KEYWORDS: watergas flow, methane migration, multiphase / multicomponent model
