Hurricane Sandy Effects on Tottenville, NY: Natural Hazard Mitigation Planning using GIS Mapping
Names:
Sandesh Lamsal, Kylee Rux, Abdullah Rahmatullah, Gustavo Aguilar

Abstract:
In October 2012, one of the most destructive hurricanes in U.S. history made landfall, referred to as Superstorm Sandy. Tottenville, NY was exposed storm surge levels of 14 feet. Following the hurricane, a national competition was launched for climate change adaptation projects. One of the selected projects was the Staten Island Living Breakwaters Project. GIS mapping was applied to pre-storm and post-storm data to assess the impacts of Hurricane Sandy and to evaluate the benefits of implementing a breakwater structure. GIS maps offered valuable insights. Tottenville’s southeast coast, consisting of high home values and concentrations of buildings, experienced significant damage. Results concerning the socio-economic landscape revealed disparities in median household income. Additional GIS maps depicted the effectiveness of breakwater structures, highlighting the potential of breakwaters for coastal protection and climate resilience. Ultimately, GIS offered visual representations and played an essential role in assessing the effect of Hurricane Sandy.

Archbold Biological Station Immature Gopher Tortoises
Name:
Leyna Stemle

Abstract: Movement data and estimation of home-range sizes provide insight into the types and amount of habitat needed to support wildlife populations, which is critical for conservation planning. Gopher Tortoises, which are important ecosystem engineers and keystone species across the southeastern US, are experiencing ongoing population declines and warrant additional habitat protection and management throughout their range. We implemented a short-term study of immature Gopher Tortoise spatial ecology at Archbold Biological Station (ABS), Florida to determine home-range size and movement levels of 3–7-yr-old tortoises. We used GPS technology to obtain high-resolution temporal tracking data. Despite the relatively short duration of our study (40 d), immature Gopher Tortoises at ABS had home-range sizes 0.38 - 1.46 ha, which are approximately 6.6-fold larger than previously reported annual home-range estimates. Our results illustrate the importance of employing new technologies to track previously difficult-to-observe life stages and improve conservation efforts for imperiled species.

Brickell Risk Mapping: Flooding & Sea Level Rise
Names:
Jason Houston, Julian Bastianello, Craig Nixon, Jacob Pultro

Abstract:
Flooding is a recurrent concern that has been affecting coastal cities for years, including Brickell - Miami, FL. The low-lying coastal location of Brickell with the constant increase of sea-level rising in past years has caused Brickell to be a main point of concern for flooding hazards and risks. To effectively prevent any flooding damage from occurring throughout the city, it is essential to see which locations are most susceptible to flooding and why. Utilizing tools such as ArcGIS to effectively view the area of concern through the lens of past data and geographical information, we can accurately assess how to map out the risk found in Brickell, Miami.

Miami-Dade County Crash Count Summary
Author:
Meenakshi Nambiar

Abstract:
Due to Miami’s unsafe and inaccessible road infrastructure, bicyclists and pedestrians are extremely vulnerable to injuries from car accidents. According to Transit Alliance Miami, pedestrian and cyclist fatalities in Miami-Dade County are almost double the national average when adjusted for population. The built environment includes road design, land-use types, surrounding establishments, and infrastructure and it can be a determining factor for which areas turn into hotspots for accidents. I gathered data on crash incidences in the county as well as the 2021 mean household income using the Miami-Dade open GIS hub and ArcGIS pro. I focused on two high-risk areas, Little Havana and SW 67th Avenue, which had the highest number of pedestrian and bike accidents. Both are located in lower-income areas and have poor road environments. Lower-income areas experience an increased incidence of traffic crashes, injuries, and deaths than higher-income areas.

Engineers Against Wet Socks: Stormwater Management at UM
Names:
William Kalis, Chris Papa, Luke Bartholomew, Jonathan Tong

Abstract:
Presented is the existing topography of Gautier Plaza on the University of Miami Coral Gables campus, located between the Knight Physics and McArthur Engineering buildings. Gautier Plaza is very susceptible to flooding, caused in part by the shifting of pavers around a number of large oak trees in the area that have created a low spot in the center of the plaza. The purpose of this endeavor is to establish a catchment area for this flood location, using ArcGIS Pro to model collected point-elevation data. In Spring 2024, our team will go on to propose design solutions for flooding in Gautier Plaza. Two potential solutions include sizing and installing a new storm drain at a low point within the catchment area, and re-grade Gautier Plaza, addressing the roots of the surrounding oak trees.

Industry Pollution and the St. Lawrence River
Name:
Marina Deane-Gonzalez

Abstract:
This project focuses on the impact of industry on the St. Lawrence River in Quebec. Using data from the Government of Canada’s website the location of industries that border the
river was mapped out and organized into 5 main sectors. Included also is an analysis of the spatial layout of these industries as well as the identity and quantity of their effluents. Water quality parameters (both average and on a parameter-by-parameter basis) were mapped on-top of that layout to determine how the industrial effluents have affected the region. The study found that throughout the river there were heightened levels of nutrients as well as the presence of many toxic man-made chemicals, though in relatively low concentrations. An overview of conservation efforts over the years is also given to provide context to the issue as well as recommendations for the future of the river.
