Recent Case Histories Of Cascade Failures And Overflowing Events Of Embankment Dams, Alexius Vogel, Jean-Robert Courivaud, Katarzyna Jarecka
Protections Conference
Excessive rainfall and extensive flooding within the context of a changing environment show the fact that resistance to overflowing erosion of embankment dams needs to be better assessed because of the increasing number of dam failures caused by overflowing, implying the necessity of a reaction to this kind of challenges. Better understandings of the embankment failure processes and the dominant parameters affecting these kinds of failures are necessary for predicting and modeling the breach processes. Acquiring this better understanding of the physical processes and a numerical prediction capability requires progressing in parallel in laboratory and field test investigations of embankment …
The Rise Of Terrorism In Africa And What It Means For U.S. Policymakers, Bridget Mary Hughes
The Rise Of Terrorism In Africa And What It Means For U.S. Policymakers, Bridget Mary Hughes
Master's Theses
This thesis utilizes three case studies to measure the rise of terrorism in Africa. This qualitative data leads the reader to one ultimate question: what does the rise in terrorism in Africa mean for the United States (U.S.) and U.S. policymakers, National Security academia, students in National Security, if anything at all? The answer is: if civilian and military compounds are being targeted by these violent extremists, as these three case studies demonstrate, it is my recommendation that U.S. policymakers cease sending troops to the African theater and, instead, allocate funding to the citizens and nonprofits of the countries whom …

Department of Agricultural and Biological Systems Engineering: Faculty Publications
Phenotyping approaches have been considered as a vital component in crop breeding programs to improve crops and develop new high-yielding cultivars. However, traditional field-based monitoring methods are expensive, invasive, and time-intensive. Moreover, data collected using satellite and airborne platforms are either costly or limited by their spatial and temporal resolution. Here, we investigated whether low-cost unmanned/unoccupied aerial systems (UASs) data can be used to estimate winter wheat (Triticum aestivum L.) nitrogen (N) content, structural traits including plant height, fresh and dry biomass, and leaf area index (LAI) as well as yield during different winter wheat growing stages. To achieve …

Techno-Economic Analysis Of Atmospheric Water Harvesting Across Climates, Natalie Gayoso
Civil Engineering ETDs
Drinking water scarcity is a global challenge as ground water and surface water availability diminishes. The atmosphere is an alternative freshwater reservoir that has universal availability and an abundance of water within the air. This makes the atmosphere a great source to capture drinking water. In order to effectively perform Atmospheric Water Harvesting (AWH) we need to 1) understand how different climate regions (e.g., arid, temperate, and tropical) drive the amount of water being produced, and 2) determine the cost to purchase, operate, and power AWH. This research pairs thermodynamics with Techno-Economic Analysis, a method of analyzing the economic performance …

Accurate and continuous precipitation monitoring is critical to enable effective water resources management; the challenge arises from the spatial and temporal variability of precipitation. The recently launched Global Precipitation Measurement (GPM) satellite has the capability to detect and measure all types of precipitation using advanced instruments. Being at its early stages of development, the products of the GPM IMERG (early, late, and final-run-products) need to be validated using multiple spatial and temporal assessment techniques. Several studies have emerged over the past few years evaluating GPM IMERG results over areas of limited size. These areas were set by hydrologic interest (e.g., …
Assessment And Prevention Of Bacterial Regrowth In Stored Household Water In Eastern Coastal Madagascar, Lauren Judah
Assessment And Prevention Of Bacterial Regrowth In Stored Household Water In Eastern Coastal Madagascar, Lauren Judah
USF Tampa Graduate Theses and Dissertations
As of 2020, diarrheal diseases were the leading cause of death in Madagascar. A major cause of diarrheal illness is contaminated water, and one crucial aspect of preventing contaminated water is safe household storage. Bacterial regrowth between point-of-collection and household storage has been well established in literature. A frequently implicated source of regrowth is the storage container’s biofilm, which is a community of varying bacteria enclosed in a “slimy” extracellular polymeric substance that forms on surfaces in wet environments and anchors bacteria to those surfaces. The overall goal of this thesis was to quantify and control bacterial regrowth in household …

Sustaining Water Conservation: A Synthesis Of Research On Motivators, Message Construction, And Tactics, Mahmudur R. Aveek, David E. Rosenberg
Civil and Environmental Engineering Student Research
Urban water managers face the challenge of sustaining conservation behavior. A review of 77 papers across water, energy, and environmental conservation was conducted to understand how programs encourage reduced water use. Motivators were external or internal. Theories of behavior change targeted different social-psychological factors. No single model addressed all aspects. Different message contents (water use, self-comparison, social comparison, leak information) and tactics (communication medium, frequency, program duration) reduced use by 0.5% to 25%. Reductions typically lasted less than a year. Quantifying the effects of specific motivators, message contents, and tactics was difficult due to varied contexts. Effective conservation messages included …
