However, there is still a noticeable scarcity of fully 3-D models, which accommodate to the sharp salt-/fresh-water interface problem, primarily due to the strong non-linearity of the governing equations and associated boundary conditions. A new finite element based model 'GEO-SWIM' is therefore developed with the main objectives to improve computational efficiency, robustness, and portability. The presented model has several features: as (1) from pure numerical point of view the embedded approach was developed in such way to avoid the two phase flow equations coupling, and (2) the FEM equations are handled efficiently using standard conjugate gradient method, preconditioned with an M-matrix based point incomplete factorization. A wide range of analytical, experimental, and field applications are used to validate the model, for many aquifer types, and under various hydrological conditions.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"A 3-D finite-element model for simulation of the moving fresh-/salt-water interface","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:32:52.928458","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":1999,"MonPub":null,"DateUpdate":"2022-03-14","DateCreate":"2002-09-23","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":0},"refs":null,"anarec":{"AnaID":27365,"PubliDate":1999,"Pagination":"91-97","XtraPublOfAnaID":null,"ISBN":null,"Volume":"79","Issue":"1-4","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43436,"SerRR":"Natuurwetenschappelijk Tijdschrift.
