Using Groundwater Modeling To Assess Groundwater And Stream Connectivity In A River Restoration Application, John Joseph Lunzer
Graduate Theses & Non-Theses
Historic placer mining operations along the Middle Fork John Day River (MFJD) north of Galena, Oregon have left the MFJD channel straightened, incised and lacking in riverbed structure. This lack of riverbed structure makes this stretch of the MFJD poor habitat for trout and migrating salmon. In order to restore this stretch of the MFJD to better serve aquatic species, Inter-Fluve Inc. (IF), United States Forest Service (USFS) and The Freshwater Trust (TFT) will be performing restoration to both the MFJD channel as well as Bear Creek, a tributary of the MFJD. The proposed restoration work will consist of re-routing …
Mountain Front Recharge In A Semi-Arid Climate, Southwest Montana, Charles Shama
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 …
