Progressive Destabilization And Triggering Mechanism Analysis Using Multiple Data For Chamoli Rockslide Of 7 February 2021, Wenfei Mao, Lixin Wu, Ramesh P. Singh, Yuan Qi, Busheng Xie, Yingjia Liu, Yifan Ding, Zilong Zhou, Jia Li
Biology, Chemistry, and Environmental Sciences Faculty Articles and Research
A catastrophic rockslide occurred on 7 February 2021 in Chamoli area in the high Himalaya. In the absence of field data, multiple satellites data of decade span have been used to investigate and understand the progressive destabilization of rockslide body. A 3D geometric model was developed using geospatial information about geology, terrain, and ice cover to understand the triggering mechanism. Several causes are uncovered as: the pronounced long-term change of land surface temperature facilitated local permafrost degradation and led to ice cover shrinking since 2010; the occurrence of ice avalanche nearby in 2016 accompanying with sidewall-to-bedrock fracturing enhanced the ice …

Using Spatial Methods To Analyse Anthropogenic Predation Risk And Movement Ecology Of White-Tailed Deer (Odocoileus Virginianus), Rhiannon D. Kirton
Electronic Thesis and Dissertation Repository
Hunting has been used as a central tool by wildlife managers to maintain populations of game species, however, we still lack a good understanding of exactly how hunting influences deer biology. Technological advances in GPS data over the last two decades now enable us to perform more detailed analysis on the effects of human hunters on wildlife populations. This research explores the spatial ecology of hunters and White-tailed deer in the Cross Timbers ecoregion of Oklahoma. Using new statistical methodologies to analyse simultaneous GPS tracking data on deer and hunters to study their spatial interactions. The results show how new …
Paleohydrological Context For Recent Floods And Droughts In The Fraser River Basin, British Columbia, Canada, Becky L. Brice, Bethany L. Coulthard, Inga K. Homfeld, Laura A. Dye, Kevin J. Anchukaitis
Paleohydrological Context For Recent Floods And Droughts In The Fraser River Basin, British Columbia, Canada, Becky L. Brice, Bethany L. Coulthard, Inga K. Homfeld, Laura A. Dye, Kevin J. Anchukaitis
Geoscience Faculty Publications
The recent intensification of floods and droughts in the Fraser River Basin (FRB) of British Columbia has had profound cultural, ecological, and economic impacts that are expected to be exacerbated further by anthropogenic climate change. In part due to short instrumental runoff records, the long-Term stationarity of hydroclimatic extremes in this major North American watershed remains poorly understood, highlighting the need to use high-resolution paleoenvironmental proxies to inform on past streamflow. Here we use a network of tree-ring proxy records to develop 11 subbasin-scale, complementary flood-and drought-season reconstructions, the first of their kind. The reconstructions explicitly target management-relevant flood and …
Bed Particle Dispersion And Scour In The San Juan (Pacheedaht) River, Meghan Sauro
Bed Particle Dispersion And Scour In The San Juan (Pacheedaht) River, Meghan Sauro
Electronic Thesis and Dissertation Repository
As part of a larger river restoration project, bed particle dispersion was tracked at pool tailouts where salmon spawning is known to occur in the San Juan (Pacheedaht) River, B.C. Mobility and pathlengths of surface and sub-surface radio-tagged particles was characterized in three reaches over two deployment years in relation to annual channel change, flow magnitude, bar morphology and particle size. Surface particle mobility was high, with results from subsurface tracers indicating high spatial variation of scour at both the reach and local scale. Results also suggest scour can occur up to depths of 0.3m at some locations, even during …
Impacts Of Sea-Level Rise On Urban Properties In Tampa Due To Climate Change, Weiwei Xie
Impacts Of Sea-Level Rise On Urban Properties In Tampa Due To Climate Change, Weiwei Xie
Theses and Dissertations
The fast urbanization produces a large and growing population in coastal areas. However, the rise of sea level, one of the most significant impacts of global warming, makes coastal communities much more vulnerable to flooding than before. This Master’s thesis study investigates sea-level rise impacts on parcel-level property in the specific coastal city of Tampa, Florida, USA. An improved sea-level rise model based on satellite altimeter data is first used to predict future sea levels. Based on high-resolution LiDAR digital elevation data and property map, flooded properties are identified to evaluate property damage cost. This empirical analysis provides an in-depth …
Risk Perception And Response Among International Students Of The University Of Southern Mississippi, Elida Lopes Souza Rocha
Risk Perception And Response Among International Students Of The University Of Southern Mississippi, Elida Lopes Souza Rocha
Master's Theses
Given the exposure of university campuses to hazards, disaster mitigation is a critical element of higher education policy. Although U.S. higher education institutions are leaders in the global education market, emergency warning systems give little consideration to how international students perceive risk, prepare for hazards, or access warning technologies available to them. This poses several questions regarding the suitability of hazards mitigation practices and the welfare of international students.
This thesis investigates the relationship between USM international students and natural hazards. Responses from online surveys and semi-structured interviews data were analyzed through qualitative and quantitative methods to document the extent …
Spatial Proximity Matters: A Study On Collaboration, Arianna Salazar Miranda, Matthew Claudel
Spatial Proximity Matters: A Study On Collaboration, Arianna Salazar Miranda, Matthew Claudel
Geography Faculty Publications and Presentations
As scientific research becomes increasingly cross-disciplinary, many universities seek to support collaborative activity through new buildings and institutions. This study examines the impacts of spatial proximity on collaboration at MIT from 2005 to 2015. By exploiting a shift in the location of researchers due to building renovations, we evaluate how discrete changes in physical proximity affect the likelihood that researchers co-author. The findings suggest that moving researchers into the same building increases their propensity to collaborate, with the effect plateauing five years after the move. The effects are large when compared to the average rate of collaboration among pairs of …
Forced And Unforced Permafrost Changes In The Northern Hemisphere During 1901-2100, Hong Guo
Forced And Unforced Permafrost Changes In The Northern Hemisphere During 1901-2100, Hong Guo
Graduate Theses and Dissertations
Permafrost regions are very sensitive to rapid changes in climate and environment. In recent decades, there has been growing interest to better understand the permafrost degradation over the Northern Hemisphere in the context of human-induced climate change. Understanding permafrost dynamics is not only important for infrastructure but also for environmental protection in cold regions. In-situ permafrost measurements are important for assessing permafrost conditions. However, direct permafrost observations are sparse and asymmetrical in both spatial and temporal coverage. Active layer thickness (ALT) modeling is another approach that can overcome many of these limitations, but the models have large uncertainty in predicting …

Examining The Effectiveness Of “Turn Around Don’T Drown”, Chance D. Bryant
LSU Master's Theses
Extreme heat is the deadliest weather hazard in the U.S. Flooding is the second worst, and flash flooding is the deadliest form of flooding. The nature of these flood deaths contains a human element that deserves greater study. Since 2004, the National Weather Service has attempted to educate the public with its slogan, ``Turn Around Don’t Drown". Vehicle related mortality rates in Texas since 1996 were examined to answer the question of whether ``Turn Around Don’t Drown" has been effective. The slogan has a large footprint on the social media platform Twitter, with most of the Tweets coming from private …

Short-Term Slope Changes On Dokdo Island Identified From Ground-Based 3d Lidar Data, Jihyun Kang, Hyejin Kim, Jaegeum Park, Hyunchul Shin
International Journal of Geospatial and Environmental Research
This study was designed to determine the slope changes on Dokdo Island, focusing on Seodo islet (slopes consisting of colluvial debris) and Dongdo islet (slopes consisting of large-scale tafoni). To do so, we obtained high-resolution 3D LiDAR data in May and November 2020 and calculated the changes in slope shape and volume over this period. Our results showed that during this time, approximately 136 m3 of colluvial debris was removed from the slopes of Seodo islet and a boulder that had separated from the massive tuff breccia migrated approximately 5 cm downslope. The major causes of such rapid changes …

Algorithm Performance On The Estimation Of Cdom And Doc In The North Slopes Of Alaska, Monica Weisenbach
Masters Theses
Use of satellite imagery makes environmental monitoring easy and convenient with little of the logistics involved in planning sampling campaigns. Colored dissolved organic matter (CDOM) is an important component to track as a proxy for the large pool of dissolved organic carbon (DOC). In a world contending with the looming issue of global climate change, the ability to investigate the carbon cycle of inland to coastal environments allows for examination of the magnitude of carbon flowing through the system and potential changes over years. The Arctic region is a critical area for climate change impacts but is a difficult landscape …
Monitoring Mammals At Multiple Scales: Case Studies From Carnivore Communities, Kadambari Devarajan
Monitoring Mammals At Multiple Scales: Case Studies From Carnivore Communities, Kadambari Devarajan
Doctoral Dissertations
Carnivores are distributed widely and threatened by habitat loss, poaching, climate change, and disease. They are considered integral to ecosystem function through their direct and indirect interactions with species at different trophic levels. Given the importance of carnivores, it is of high conservation priority to understand the processes driving carnivore assemblages in different systems. It is thus essential to determine the abiotic and biotic drivers of carnivore community composition at different spatial scales and address the following questions: (i) What factors influence carnivore community composition and diversity? (ii) How do the factors influencing carnivore communities vary across spatial and temporal …

The Holocaust In Białystok: Urban, Rural, And Forest Environments As Spaces Of Resistance, Survival, And Persecution, Dakota Gramour
Electronic Theses and Dissertations
During the German occupation of Poland in World War II, thousands of Jews escaped city or ghetto life by seeking refuge within rural villages or fleeing to the forests. Numerous factors shaped individual survivor experiences within these spaces. In particular, gender, age or familial status, environmental factors like weather conditions or terrain, as well as personal politics and language or technical skills, all molded how one could act or was forced to react in these spaces. This study emphasizes the unique two-way relationships between experience and three kinds of environments found in the Białystok District: the city of Białystok, small …
On Aqueducts And Anxiety: Water Infrastructure, Ruination, And A Region-Scaled Anthropocene Imaginary, Sayd Randle
On Aqueducts And Anxiety: Water Infrastructure, Ruination, And A Region-Scaled Anthropocene Imaginary, Sayd Randle
Research Collection College of Integrative Studies
This paper explores popular expectations for and meanings of the U.S. West's environmental future, as articulated through recent artistic representations of the Los Angeles's expansive water provision network. Weaving together material from participant observation and readings of creative works, I show how infrastructural imagery is used to index anxieties about a future of water scarcity. Presenting familiar, currently functional water infrastructures as ruins-in-the-making, these artists use the physical stuff of water provision networks to advance critiques of longstanding modes of development and the material basis of urban-rural relations in the U.S. West. Doing so, these imagined ruins draw the global-scale …

How Do Environmental Factors Affect Drivers’ Gaze And Head Movements?, Arash Tavakoli, Vahid Balali, Arsalan Heydarian
Mineta Transportation Institute Publications
Studies have shown that environmental factors affect driving behaviors. For instance, weather conditions and the presence of a passenger have been shown to significantly affect the speed of the driver. As one of the important measures of driving behavior is the gaze and head movements of the driver, such metrics can be potentially used towards understanding the effects of environmental factors on the driver’s behavior in real-time. In this study, using a naturalistic study platform, videos have been collected from six participants for more than four weeks of a fully naturalistic driving scenario. The videos of both the participants’ faces …
Firesafe: Designing For Fire-Resilient Communities In The American West, Brenden Baitch
Firesafe: Designing For Fire-Resilient Communities In The American West, Brenden Baitch
Masters Theses
The perception that wildfires are completely preventable has caused many structures and communities to be built in locations that will inevitably experience an uncontrollable fire event, risking human lives and infrastructure. Modification of built environments into fire-adapted communities has been explored in this thesis, through multiple strategies. Central to this analysis is the idea that sustainable human developments could adopt a form of biomimicry and indigenous design informed by the adaptions of plants, animals, and native groups that endure and even thrive with regular cycles of fire. This possibility has been assessed through the scope of fire adaptation strategies available …
Geolocation Of Monitoring Wells Using Small Unmanned Aircraft Systems, Joel Deyoung
Geolocation Of Monitoring Wells Using Small Unmanned Aircraft Systems, Joel Deyoung
Graduate Theses and Dissertations
Groundwater monitoring wells are commonly installed on a property as part of an environmental investigation to observe hydrological subsurface conditions, facilitate the collection of groundwater samples, and predict the flow of groundwater across a site. In addition to their installation, monitoring wells should be surveyed or mapped as accurately as possible. Traditional surveying techniques have employed the use of global navigation satellite systems (GNSS) technologies or other surveying equipment. A common surveying approach is to use real-time kinematic (RTK) GNSS to accurately measure the coordinates of each monitoring well on the site.In recent years, drones, or small unmanned aircraft systems …

International Journal of Geospatial and Environmental Research
Walkability is one of the issues to be addressed in the planning of smart urban cities. Although, there is a substantial amount of studies on outdoor walking pedestrian, limited study has been done to address indoor walkability. Recently, most of the pedestrians are likely to use indoor route than outdoor route to protect themselves from sun and rain as most of the indoor routes are located on the buildings such as shopping mall and rail transit station. Therefore, it important to collect all the relevant information in the indoor building to addressed the walkability issues. The GeoSLAM ZEB REVO scanner …

Environmental Cues And The Sociospatial Imaginary: An Examination Of Spatial Perception And Meaning-Making In A Gentrifying Neighborhood, Todd Levon Brown
Dissertations, Theses, and Capstone Projects
What could be more ordinary or pedestrian than two people walking down an urban street and talking about what we see and what we make of it? Yet this simple, quotidian act of walking a street—seeing, perceiving and experiencing physical spaces, places and objects—and making meaning of what is encountered, is the basis of my dissertation. It is also my basis for claiming that I have learned a great deal—and much unexpectedly—about how differently different people see and interpret the urban streetscape. What are the various environmental cues that stand out to different individuals? What are the psychosocial imaginaries that …
Composite Analysis Of Mendenhall Glacier Interannual Glacial Health Decline, Hailey Marie Cantrell
Composite Analysis Of Mendenhall Glacier Interannual Glacial Health Decline, Hailey Marie Cantrell
Masters Theses
Glacial health in Alaska, USA is demonstrating an interannual declining trend. Repetitive years have suffered an imbalance between winter seasonal ice accumulation and summer seasonal ice loss. Increased ice loss has commonly been attributed to warmer Arctic summer temperatures, which contribute to greater calving events and amplified ablation. Study of the unique climatic influences by different variables is ongoing and at the forefront of climate-glacier interaction research.
This study is designed to quantitatively evaluate correlations between changes in Alaskan climatic patterns and an interannual trend of declining glacial health for Mendenhall Glacier by combining analysis of Landsat satellite imagery, teleconnection …
