Change Is The Only Constant: A Snowpack Retention Analysis And Climate Vulnerability Road Map For The Skalkaho Creek Sub-Basin, Zachary Freeman Goodwin
Change Is The Only Constant: A Snowpack Retention Analysis And Climate Vulnerability Road Map For The Skalkaho Creek Sub-Basin, Zachary Freeman Goodwin
Graduate Student Theses, Dissertations, & Professional Papers
Climate change is impacting the whole of North America, although the impacts differ depending on regional geography. In the Intermountain West, climate change is contributing to lower overall snowpack totals and diminished late season streamflows. These changes will likely contribute to vulnerabilities in how much water is available to irrigators, municipalities, and fisheries dependent upon a consistent yearly flow of meltwater. This paper explores how snowpack retention has changed via the NASA dataset Daymet, which provides gridded estimates of weather parameters including Snow Water Equivalent in the Bitterroot River Basin of western Montana. This analysis showed that snowpack retention from …
Utilization Of Various Methods And A Landsat Ndvi/Google Earth Engine Product For Classifying Irrigated Land Cover, Andrew Nemecek
Utilization Of Various Methods And A Landsat Ndvi/Google Earth Engine Product For Classifying Irrigated Land Cover, Andrew Nemecek
Graduate Student Theses, Dissertations, & Professional Papers
Methods for classifying irrigated land cover are often complex and not quickly reproducible. Further, moderate resolution time-series datasets have been consistently utilized to produce irrigated land cover products over the past decade, and the body of irrigation classification literature contains no examples of subclassification of irrigated land cover by irrigation method. Creation of geospatial irrigated land cover products with higher resolution datasets could improve reliability, and subclassification of irrigation by method could provide better information for hydrologists and climatologists attempting to model the role of irrigation in the surface-ground water cycle and the water-energy balance. This study summarizes a simple, …
Remote Sensing Of Avalanche Paths In Glacier National Park, Montana, Morgan Voss
Remote Sensing Of Avalanche Paths In Glacier National Park, Montana, Morgan Voss
Graduate Student Theses, Dissertations, & Professional Papers
Snow avalanches are the common form of mass wasting in the high mountain environments of Glacier National Park (GNP), Montana. These natural disturbances play important roles in mountain ecosystems by regularly disturbing montane systems, providing critical habitat for some species, transporting debris, and influencing vegetation and fire dynamics. Since the 1900s, natural avalanche-related activity recorded along important transportation corridors within the park has frequently disrupted transportation.
While many of the steep slopes of GNP are susceptible to avalanching, formal inventories exist only for small, critical portions of the park and they vary substantially from one another. GNP’s protected status does …
