Hydrogéologie et Géochimie
ITASCA possède la compétence scientifique, l'expérience et les outils numériques nécessaires à la mise en oeuvre de modèles mathématiques permettant la résolution de problèmes d'hydrogéologie des milieux poreux et fracturés. ITASCA développe (et finance) en collaboration avec l'INRIA, son propre outil d'analyse 3FLO, logiciel tri-dimensionnel de calculs d'écoulement et de transport de masse.
Propagation d'un panache hyper-alcalin (Modélisation 3FLO)
Cet outil est adapté à la résolution de problèmes dans les domaines suivants:
Gestion des eaux dans les travaux souterrains
- Drainage, rabattement de nappes et réinjection,
- Confinement par parois étanches,
- Creusement de galeries et stabilité des terrains.
Ressources en eaux - gestion des nappes
- Interprétation d'essais de puits,
- Interprétation de tests de traçages,
- Modélisation de cônes de rabattement,
- Diagnostic géochimique
