Tweet Diffusion Over Space And Time: A Comparison Of A Winter-Weather And Tornado-Outbreak Case Study, Alyssa Margaret Cannistraci
Tweet Diffusion Over Space And Time: A Comparison Of A Winter-Weather And Tornado-Outbreak Case Study, Alyssa Margaret Cannistraci
Masters Theses
Social media allows people to receive, engage in, and share weather information. Users of the social media platform Twitter actively share weather content via tweets, which researchers can acquire through an Application Programming Interface (API). APIs return tweet content, as well as temporal and spatial characteristics (latitude and longitude coordinates). Tweets can then be mapped and studied spatiotemporally through Geographic Information System (GIS) software. For this work, I compared how tweets spread (“diffuse”) over space and time during two natural hazard events in the United States. The first case study is a winter weather event that The Weather Channel named …

In the meandering riverbank of the Upper Yellow River (UYR), the native alpine swamp meadow (AS) has continuously degenerated into an alpine meadow (AM) due to climate change and intensified grazing. Its implication on river morphology is still not well known. This study examined this effect by in situ measurings of (1) physical properties of roots and their distribution in the soil-root mixture of the upper bank layer, and (2) the tensile strength in terms of excavating tests for triggering cantilever collapses of AS and AM riverbanks. The results showed that the root number in AS was significantly greater than …
Crude Oil Spill Response In The Great Lakes Region: Before And After The 2010 Kalamazoo River Enbridge Oil Spill, Marshall Kim
Crude Oil Spill Response In The Great Lakes Region: Before And After The 2010 Kalamazoo River Enbridge Oil Spill, Marshall Kim
Honors Theses
Pipeline infrastructure is a particularly sensitive and unique energy transport mode. Pipelines carry gas, biofuels and liquid petroleum throughout the United States (U.S. Department of Transportation, 2019). These pipelines stretch beneath sensitive ecological areas, lakes, rivers and streams, and our homes and businesses. According to the Pipeline and Hazardous Materials Safety Administration (PHMSA) (2018), between all of the states in the Great Lakes region (Illinois, Indiana, Michigan, Minnesota, New York, Ohio, Pennsylvania and New York) there is a cumulative 801,718 miles of pipeline. This includes interstate and intrastate, natural gas and petroleum pipelines. 9,556.9 miles of this is the interstate …
Desarrollo De Un Esquema De Gestión Hídrica En El Sistema Acuífero Sap 3.1 Apoyado De La Tipificación De Suelos Y El Modelo Conceptual De Thöt, Maria Camila Soriano Espinosa, Camilo José Rodríguez Carvajal
Desarrollo De Un Esquema De Gestión Hídrica En El Sistema Acuífero Sap 3.1 Apoyado De La Tipificación De Suelos Y El Modelo Conceptual De Thöt, Maria Camila Soriano Espinosa, Camilo José Rodríguez Carvajal

El presente proyecto tiene como objetivo principal desarrollar un esquema de gestión hídrica (EGH) en el sistema acuífero SAP 3.1, provincia llanos orientales, con base en la tipificación de suelos y el modelo conceptual de Tӧth, partiendo de que las aguas subterráneas se consideran una fuente alternativa de abastecimiento por su mejor calidad y el bajo costo de manejo en comparación al agua superficial, y teniendo en cuenta que el Departamento del Meta conoce la riqueza hídrica que está en su jurisdicción, no cuenta con una regulación adecuada en pro de una gestión hídrica a nivel subterráneo. La metodología empleada …
