What's GEOSTUDIO

GeoStudio offers a range of numerical analysis tools to simulate conditions above and below the ground surface. GeoStudio can be used to model natural terrain and rock slopes, groundwater flow systems for geotechnical applications, open-pit excavations and mining, drainage systems, earth dams and embankments, reinforced earth structures, tailings storage facilities, and more.
