Assessment Of Pluvial Flooding In Syracuse, Ny, Using High-Resolution Topographic Data, Yngrid Pereira Marques
Assessment Of Pluvial Flooding In Syracuse, Ny, Using High-Resolution Topographic Data, Yngrid Pereira Marques
Theses - ALL
Although there have been many advances in regulations to assess flood risk in urban environments, the majority of these investigations to date have focused on fluvial or coastal flooding. However, in urban systems, pluvial flooding continues to be a pressing issue in need of attention. Due to the limited research on pluvial flooding in Syracuse, NY, its population and assets are exposed to the risks imposed by this type of flooding, as their primary metric for delineating flood risk is the traditional riverine flood zones designated by the Federal Emergency Management Agency (FEMA). To address this issue, this research implemented …
Integrated Water Quality Monitoring Of Skaneateles Lake Tributaries, Mengyi Zhang
Integrated Water Quality Monitoring Of Skaneateles Lake Tributaries, Mengyi Zhang
Theses - ALL
Skaneateles Lake is the drinking water source for the City of Syracuse and surrounding areas. Harmful algal blooms (HABs) have been occurring in Skaneateles Lake every year since 2017 and posing a great threat to water quality and drinking water safety. Although the exact cause of the HABs is still unclear, sunlight, quiescent conditions, warm temperature, and elevated concentrations of nitrogen and phosphorus seem to favor the development of such blooms. In this study, a custom-built, low-cost, multi-parameter sensor unit was designed, built, and deployed on a third-order tributary. The unit collected high-frequency data for stage, temperature, pH, and dissolved …
Hydrus-1d Modeling To Represent Hydrologic Performance Of The Oncenter Green Roof, Courtney Gammon
Hydrus-1d Modeling To Represent Hydrologic Performance Of The Oncenter Green Roof, Courtney Gammon
Theses - ALL
Green infrastructure has the potential to alleviate stormwater runoff and reduce combined sewer overflows. Green roofs have stormwater mitigation potential in urban areas but further analysis to predict performance is needed. This research aims to understand how rainfall parameters affect green roof retention and reduction during storm events and whether a one-dimensional hydrologic model can be used to accurately predict performance. An extensive network of sensors on the OnCenter green roof in downtown Syracuse, New York, was utilized for analysis and modeling. This roof is larger than nearly all other green roofs that have been previously studied, and the layer …
Stress-Strain Behavior By Image Analysis, Mix Density And Pre-Strain Effects Of Eps Geofoam, Chen Liu
Stress-Strain Behavior By Image Analysis, Mix Density And Pre-Strain Effects Of Eps Geofoam, Chen Liu
Theses - ALL
In order to have a deeper understanding of the engineering performances of EPS geofoam, it is necessary to study the stress-strain response and internal strain distribution when loaded. In this investigation, the key objective is to study the stress-strain behavior of EPS geofoam under different conditions and develop construction practical suggestions when using geofoam. The scope of this research is divided into three main sections: (1) study the effect of induced anisotropy on the stress-strain behavior of EPS geofoam; (2) evaluate stress distribution within EPS blocks by using image analysis system; (3) analyze the effect of combining different EPS densities …

With the recent growth of the natural gas industry coupled with technological advancements, gas shale fracturing has become an effective and highly profitable method for natural gas production. Unlike conventional natural gas extraction which may require vertical fracturing, gas shale fracturing relies on a method known as horizontal fracturing to remove gas trapped within the impermeable facies. Compared to vertical fracturing, horizontal fracturing requires larger amounts of fluids to be injected downhole under high pressure. These fracturing fluids can contain high concentrations of petroleum hydrocarbons with known adverse health effects. Due to the large volumes used, the potential for groundwater …
