Mountain Front Recharge In A Semi-Arid Climate, Southwest Montana, Charles Shama
Graduate Theses & Non-Theses
Groundwater recharge to regional valley benches originates largely from adjacent Mountain Front Recharge (MFR). The Madison Valley in Southwest Montana is a semi-arid cold climate that receives 31.75cm annual valley precipitation. In this study, two drainages are characterized and compared, looking at the hydrological processes between the stream and groundwater. North Meadow Creek is a high elevation stream dominated by snowmelt and contains reaches of gaining and losing surface water to groundwater. Daylight Creek is a spring fed disconnected stream. Methods used a surface water balance, temperature as an environmental tracer and two and three component mixing models to investigate …

Uav-Based Geotechnical Modeling And Mapping Of An Inaccessible Underground Site, Elizabeth Anne Russell
Graduate Theses & Non-Theses
Digital photogrammetry is becoming a more common method used for mapping geological and structural rock mass features in underground mining. The issue of capturing geological and structural data in inaccessible, unsupported areas of mines remains even when utilizing terrestrial photogrammetric methods; thus, geotechnical models of mines are left with incomplete datasets. Large unsupported underground voids, like stopes, have the potential to cause major failures, but by filling in the geotechnical data gaps in inaccessible areas, potential failures can be predicted through kinematic analysis of the area’s mapped discontinuities. Implementation of Unmanned Aerial Vehicles (UAVs) in underground mines and recent advances …
