Spatial And Temporal Controls On Streamflow Variability In The San Juan Mountains, Colorado, Christopher Lewis Hancock Jan 2020

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 …


Paleoflood Hydrology And Basin Morphometric Characteristics Related To Flooding In The Colorado Front Range, Natalie Trivino Jan 2018

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 …


Rock Glacier Hydrology In The San Juan Mountains, Colorado, Emilio Ian Mateo Jan 2017

Rock Glacier Hydrology In The San Juan Mountains, Colorado, Emilio Ian Mateo

Electronic Theses and Dissertations

Rock glaciers are unique geomorphological features located in alpine environments and are found in the San Juan Mountains of Colorado. There has been little research done on rock glaciers compared to their ice glacier counterparts. Most rock glaciers are located on the northern slope aspect in mountainous areas (Janke 2007), however, there are multiple in southwest Colorado with different aspects. This research project asks how slope aspect influences the hydrological processes of streams sourced from rock glaciers in the San Juan Mountains. This project focused on three basins that are adjacent to each other and share a common peak, Gilpin …
