description

Kvartāra nogulumu reprezentācija reģionālā hidroģeoloģiskā modelī ir sarežģīta problēma šo nogulumu heterogenitātes un tās atspoguļošanai nepietiekamā urbumu griezumu datu apjoma dēļ. Lai to uzlabotu, tiek izstrādāta darba gaita, kas ļauj ģeneralizēt kvartāra nogulumu slāņiem atbilstošo filtrācijas modeļa īpašību 3D ģeometrijas struktūru, izmantojot normalizēto kompresijas distances (NKD) metriku - inovatīvu metodi neparametriskajā mašīnapmācībā, kas līdz šim brīdim ir maz lietota ģeozinātnēs. Darba gaitā izveidoto ģeneralizāciju atbilstība tiek pārbaudīta ar modeļsistēmas aprēķiniem. Tiek iegūts rezultātu uzlabojums, salīdzinot ar agrāko reģionālā modeļa kvartāra slāņu reprezentāciju filtrācijas modeļa 3D struktūrā. Šis NKD lietojums ir oriģināls un potenciāli noderīgs citu Zemes sistēmas daļu modelēšanai.
