Implications Of Dam Removal: Modeling Streamflow In Lansing, Michigan Using The Soil And Water Assessment Tool, Ryan J. Filbin, Laiyin Zhu, Lisa Dechano-Cook, Lei Meng
International Journal of Geospatial and Environmental Research
This paper uses hydrologic modeling methods to determine the effects of dam removal in Lansing, Michigan, on the streamflow of the Grand River, flooding risks, and flood mitigation strategies. In Michigan, more than one-half of the state’s dam infrastructure is more than 50 years old, and more than one-third are classified as having a moderate-to high-risk potential. Lansing, Michigan, contains two moderate-to high-risk dams along the Grand River that are a significant hazard to the surrounding community in the event of structural failure. This research utilizes the Soil and Water Assessment Tool (SWAT) to model the impacts of the ...
Timing And Formation Of Linear Dunes South Of The Niobrara River Valley, North-Central Nebraska Sand Hills, 2018 University of Nebraska-Lincoln
Timing And Formation Of Linear Dunes South Of The Niobrara River Valley, North-Central Nebraska Sand Hills, Ashley K. Larsen
Theses and Dissertations in Geography
The Nebraska Sand Hills is a vast (7500 square kilometer) area of grass-stabilized sand dunes. Larger dunes in the Nebraska Sand Hills formed primarily during the Late Pleistocene, but many underwent widespread reactivation during the Holocene. Recent Optically Stimulated Luminescence (OSL) dating indicates that the last major phase of reactivation in the Sand Hills was during the Medieval Warm Period, approximately 800 years ago. Nevertheless, many questions about the evolution of the dunes remain unanswered, particularly regarding the formation of linear dunes in portions of the Sand Hills.
This study seeks to understand more about the formation of linear dunes ...

Mackinder And The Arctic's Emerging Geopolitics: Recommendations For The U.S. And Its Nato Allies, Bert Chapman
Libraries Faculty and Staff Presentations
This presentation shows how Halford Mackinder (1861-1947) described Canada and the Arctic region in his geopolitical writings. It goes on to stress how the Arctic is becoming increasingly important in international geopolitical policymaking due to its significant oil and natural gas resources, how warming temperatures are increasing international access to its waters, and the how countries as diverse as Canada, China, Russia, and the U.S. see the Arctic region in their strategic policymaking. It concludes by stressing that the Arctic can no longer be viewed as a region immune from international conflict and presents recommendations for the U.S ...

Adapting To Climate Change Through Source Water Protection: Case Studies From Alberta And Saskatchewan, Canada, 2018 University of Saskatchewan
Adapting To Climate Change Through Source Water Protection: Case Studies From Alberta And Saskatchewan, Canada, Robert J. Patrick
The International Indigenous Policy Journal
The protection of drinking water sources continues to gain momentum in First Nation communities on the Canadian Prairie. Through the identification of potential threats to drinking water sources communities are taking action to mitigate those threats. This article explores the extent to which climate change has been taken into consideration in recent source water protection planning community exercises. In addition, this article describes how source water protection planning has potential to enhance community adaptation strategies to reduce the impacts of climate change on source water and drinking water systems. Results are based on six case studies from Alberta and Saskatchewan.

Estimation Of The Relationship Between Satellite-Derived Vegetation Indices And Live Fuel Moisture Towards Wildfire Risk In Southern California, Kristen Whitney, Seung Hee Kim, Shenyue Jia, Menas Kafatos
Mathematics, Physics, and Computer Science Faculty Articles and Research
Southern California possesses a Mediterranean climate having semi-arid to arid characteristics and contains shrubland areas at high risk to wildfire. To assess wildfire danger, fire agencies have been monitoring the moisture of vegetation, called live fuel moisture (LFM), using field-based sampling. Unfortunately, spatial and temporal resolution of live fuel moisture data are significantly limited because sampling is labor intensive. Remote sensing satellite data has been used to monitor vegetation moisture content and health of shrublands. Therefore, a potential approach to overcome the limitations of manual measurements of live fuel moisture is to use vegetation indices (VIs) derived from satellite data ...
Landscape Drivers Of Recent Fire Activity (2001- 2017) In South-Central Chile, 2018 Montana State University-Bozeman
Landscape Drivers Of Recent Fire Activity (2001- 2017) In South-Central Chile, David B. Mcwethy, Aníbal Pauchard, Rafeal García, Andrés Holz, Mauro E. Gonzales, Thomas T. Veblen, Julian Stahl, Bryce Currey
Geography Faculty Publications and Presentations
In recent decades large fires have affected communities throughout central and southern Chile with great social and ecological consequences. Despite this high fire activity, the controls and drivers and the spatiotemporal pattern of fires are not well understood. To identify the large-scale trends and drivers of recent fire activity across six regions in south-central Chile (~32–40° S Latitude) we evaluated MODIS satellite-derived fire detections and compared this data with Chilean Forest Service records for the period 2001–2017. MODIS burned area estimates provide a spatially and temporally comprehensive record of fire activity across an important bioclimatic transition zone between ...
The Impact Of World War One On The Forests And Soils Of Europe, 2018 University of Northern Colorado
The Impact Of World War One On The Forests And Soils Of Europe, Jason Andrew Heiderscheidt
Ursidae: The Undergraduate Research Journal at the University of Northern Colorado
The First World War was one of the deadliest conflicts in human history thus far. With the human toll being over eight million deaths, and millions more wounded, and as such it has taken hold in peoples imaginations for over a hundred years. However, one overlooked impact of the war is the environmental impact it had. The forests of Europe were significantly changed, going from being diverse ecosystems pre-war to monocultures after the war, dominated by single species of trees. The soil was also affected, more heavily in some places, becoming contaminated with heavy metals, as well as becoming entirely ...

Forewarned Is Forearmed: Review Of Curbing Catastrophe: Natural Hazards And Risk Reduction In The Modern World By Timothy H. Dixon (2017), Jason Makansi
Timothy H. Dixon. 2017. Curbing Catastrophe: Natural Hazards and Risk Reduction in the Modern World. (New York, NY: Cambridge University Press) 300 pp. ISBN 978-1108113663.
Curbing Catastrophe for the most part lives up to what is claimed in the foreword: “…a compelling account of recent and historical disasters, both natural and human-caused, drawing on common themes and providing a holistic understanding of hazards, disasters, and mitigation for anyone interested in this important and topical subject.” This is a pretty thorough treatment of an extraordinarily complex subject, and the gaps identified in this review should be considered explications more than criticisms.

Large Scale Climate Oscillation Impacts On Temperature, Precipitation And Land Surface Phenology In Central Asia, 2018 University of Oklahoma
Large Scale Climate Oscillation Impacts On Temperature, Precipitation And Land Surface Phenology In Central Asia, Kirsten M. De Beurs, Geoffrey Henebry, Braden C. Owsley, Irina N. Sokolik
GSCE Faculty Publications
Central Asia has been rapidly changing in multiple ways over the past few decades. Increases in temperature and likely decreases in precipitation in Central Asia as the result of global climate change are making one of the most arid regions in the world even more susceptible to large-scale droughts. Global climate oscillations, such as the El Ni ̃no–Southern Oscillation, have previously been linked to observed weather patterns in Central Asia. However, until now it has been unclear how the different climate oscillations act simultaneously to affect the weather and subsequently the vegetated land surface in Central Asia.We fit ...
