Rock Glacier Development In The San Juan Mountains, Brandon K. Bailey
Rock Glacier Development In The San Juan Mountains, Brandon K. Bailey
Electronic Theses and Dissertations
Rock glaciers are common landform features found in deglaciated alpine areas. They are commonly used in the study of climatic changes throughout the Holocene and the reconstruction of neoglacial chronologies. For this research, Schmidt hammer rebound values, weathering rind thicknesses, and the length of lichen thalli diameters found on rock glacier surfaces are used to investigate their effectiveness as field-based relative age determination techniques. Additionally, the ability to identify periods of neoglacial activity using these methods is assessed in two neighboring cirque basins in the San Juan Mountains of Colorado. 41 field sites across three rock glaciers are established with …
Spatial And Temporal Controls On Streamflow Variability In The San Juan Mountains, Colorado, Christopher Lewis Hancock
Spatial And Temporal Controls On Streamflow Variability In The San Juan Mountains, Colorado, Christopher Lewis Hancock
Electronic Theses and Dissertations
This project characterizes and examines changes to the annual hydroclimatic cycle throughout alpine regions of Colorado with a focus on trends in snowpack and snowmelt hydrology. Datasets analyzed for this research include 79 SNOTEL sites throughout Colorado (24 in the San Juan Mountains) which provide climate metrics for Water Years 1988-2018. Impacts on streamflow are evaluated in the San Juan Region through a network of 11 USGS stream gauges. Correlation matrices and linear regression methods examine the relative controls on the magnitude and timing of discharge, and trend detection using the regional Kendall test quantifies the rate of change within …
Corporate-Community Mining Conflicts In Guatemala: Unsettling Hegemonic Power Relations In Environmental Struggles, Anna Guðbjört Sveinsdóttir
Corporate-Community Mining Conflicts In Guatemala: Unsettling Hegemonic Power Relations In Environmental Struggles, Anna Guðbjört Sveinsdóttir
Electronic Theses and Dissertations
This dissertation analyzes corporate-community conflicts around extractive industries in Guatemala with the purpose of better understanding how environmental struggles emerge and take shape. The study uses environmental governance as a framework to analyze the processes, institutions, actors and discourses that shape the conditions of possibility of political action and mobilization in environmental struggles. The dissertation argues that to understand the conditions of possibility of political action and mobilization in environmental struggles we must study the interplay between political actions 'from above' and 'from below', which are seen as dialectically interrelated, with dynamic and contested interactions between actors within and between …
Paleoflood Hydrology And Basin Morphometric Characteristics Related To Flooding In The Colorado Front Range, Natalie Trivino
Paleoflood Hydrology And Basin Morphometric Characteristics Related To Flooding In The Colorado Front Range, Natalie Trivino
Electronic Theses and Dissertations
Flooding hazards are common in the Colorado Front Range due to the steep, complex terrain of the mountains where waters quickly spill out onto the most populated region of Colorado. This region has experienced numerous catastrophic floods, such as the 2013 Front Range Floods, the Fort Collins Flood of 1997, and the Big Thompson Canyon Flood of 1976 to name a few. The objective of this study was to analyze basin morphometric characteristics of several drainage basins throughout the Colorado Front Range South Platte River tributaries and determine how these characteristics relate to extreme flooding. This was done through three …
