20.500.12556/RUL-32121 A comparison of the effectiveness of using the meshless method and the finite difference method in geostatistical analysis of transport modeling Disposal of radioactive waste in geological formations is a great concern with regards to nuclear safety. The general reliability and accuracy of transport modeling depends predominantly on input data such as hydraulic conductivity, water velocity, radioactive inventory, and hydrodynamic dispersion. The most important input data are obtained from field measurernents, but they are not always available. One way to study the spatial variability of hydraulic conductivit,y is geostatistics. The numerical solution of partial differential equations (PDEs) has usually been obtained by finite difference methods (FDM), finite element methods (FEM), or finite volume methods (FVM). These methods require a mesh to support the localized approximations. The multiquadric (MQ) radial basis function meihod is a recent meshless collocation method with global basis functions. Solving PDEs using radial basis function (RBF) collocations is an attractive alternative to these traditional methods because no tedious mesh generation is required. We compare the meshless method, which uses radial basis functions, with the traditional finite difference scheme. ln our case we determine the average and standard deviation of radionuclide concentration with regard to spatial variability of hydraulic conductivity that was modeled by a geostatistical approach. transport modeling Kansa method radial basis function geostatistics true false false World Scientific Publishing Angleški jezik Angleški jezik Neznano 2015-07-10 10:12:09 2015-07-10 10:12:10 2022-11-21 15:07:27 0000-00-00 00:00:00 2005 0 0 Str. 149-166 št. 2 Letn. 2 2005 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 519.2 10.1142/S0219876205000405 506718 506462 Ijcm_2edited_.pdf Ijcm_2edited_.pdf 1 27F16B0BFFDC3757D150ABF0B76C85E3 c2a4ed022b9d8b11637766f2f7d896220769eb4e7f3b3f6dcca800cf35d3abe7 0fb36155-a1ae-11eb-a523-00155dcfd717 20.500.12556/rul/482c560e-2b90-4866-a56e-770a5172d401 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=85631 Fakulteta za gradbeništvo in geodezijo 0 0 0
