Identifying Watershed And Climatic Factors That Influence Headwater Streams In The San Bernardino National Forest - A Framework For Adaptive Management And Conservation, Christine Sue Seeger
Identifying Watershed And Climatic Factors That Influence Headwater Streams In The San Bernardino National Forest - A Framework For Adaptive Management And Conservation, Christine Sue Seeger
Electronic Theses, Projects, and Dissertations
Headwater streams play a significant role in overall watershed condition. These streams are critical freshwater resources and are imperative for human and ecosystem health. Seasonal variability in climate patterns is becoming increasingly more common as the effects of climate change are studied. The phenomenon known as “weather whiplash,” prolonged periods of drought followed by a sudden increase in precipitation, creates additional challenges for human and ecosystem conditions. Factors adversely impacting headwater streams include climate change, drought, wildfires, and human influence. While climate change continues to be studied, little is known about how weather whiplash patterns affect headwater streams in Southern …
Delineating A Stream Network At Gale Crater, Mars, On Arcgis Pro: A Geographic Information Systems Approach, Elpidio Guzman De La Cruz
Delineating A Stream Network At Gale Crater, Mars, On Arcgis Pro: A Geographic Information Systems Approach, Elpidio Guzman De La Cruz
West Chester University Master’s Theses
The northwestern region of the Gale crater experienced flooding in the past. Delineation of stream networks for the northwestern region of Gale Crater, Mars employing geographic information systems (GIS) techniques is applied. The stream network produced by the algorithm in the study traverses the clay unit in Gediz Vallis, and visual HiRISE imagery analysis correlates with a topologic cross section of an inverted river channel of 750 meters wide and 90 meters deep. HiRISE imagery analysis further confirms a sulfate and clay stratigraphic unit in a stream 125 meters wide and 25 meters deep. Lastly, data smoothing procedures in the …
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 …
An Analysis Of The Relationship Between Snowpack And Groundwater Across Utah Watersheds., Samuel Wright
An Analysis Of The Relationship Between Snowpack And Groundwater Across Utah Watersheds., Samuel Wright
Electronic Theses and Dissertations
This thesis examined what type of relationship existed between snow water equivalence (SWE) volume and groundwater elevation within six sub-watersheds in Utah. Data was gathered on SWE from seventeen SNOTEL sites and groundwater elevation data was gathered from six continuously monitored groundwater wells. This data was gathered for January through May for 2011, 2013, and 2014 in order to represent the water conditions that were above average, below average, and average respectively. Using MLR formulas the total SWE for each sub-watershed was determined for each year/month. Afterwards a correlation analysis was performed to determine if any association existed between SWE …
Integrated (Remote Sensing, Gis, And Modeling) Hydrological Investigation And Landslide Susceptibility Studies In The Arabian Shield, Talal Ghazi Alharbi
Integrated (Remote Sensing, Gis, And Modeling) Hydrological Investigation And Landslide Susceptibility Studies In The Arabian Shield, Talal Ghazi Alharbi
Dissertations
An integrated approach (remote sensing, geographical information systems [GIS], and modeling) was applied to conduct a number of hydrologic and environmental investigations in the Arabian Peninsula (AP) aimed at: (1) identifying the spatial and temporal climate change–related variations in precipitation over the AP using readily available, remotely acquired global precipitation data sets; (2) investigating the nature of the factors controlling the observed climatic variations; (3) estimating the partitioning of precipitation over the Red Sea Hills watersheds into runoff , recharge, and initial losses using calibrated continuous rainfall runoff models (Soil Water Assessment Tool [SWAT]); (4) identifying landslide (largely caused by …
