Applying Gis Software To Visualize Temporal Changes In Drinking Water Quality Sources, Salam Radhaa

Undergraduate Student Research Internships Conference

The Chippewas of the Thames First Nation Reserve in southwestern Ontario has been under a Boil Water Advisory for an extended period of time. This project aims to create a framework to address this issue by detecting possible pollutants and presenting in a visual manner.

Several sample sites are utilized to determine the source of pollution as there are many possibilities: upstream overflow events, farm runoff, other point sources upstream. Extra care will go to sampling within 24hr of a significant precipitation event to measure spikes in pollutants that have accumulated during dry periods.

ArcGIS software (ArcMap) is utilized as …

Temporal Lidar Scanning In Quantifying Cumulative Rockfall Volume And Hazard Assessment: A Case Study At Southwestern Saudi Arabia, Abdullah A. Alotaibi, Norbert H. Maerz, Kenneth J. Boyko, Ahmed M. Youssef, Biswajeet Pradhan

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

Rockfalls and unstable slopes pose a serious threat to people and property along roads/highways in the southwestern mountainous regions of Saudi Arabia. In this study, the application of terrestrial light detection and ranging (LiDAR) technology was applied aiming to propose a strategy to analyze and accurately depict the detection of rockfall changes, calculation of rockfall volume, and evaluate rockfall hazards along the Habs Road, Jazan Region, Saudi Arabia. A series of temporal LiDAR scans were acquired at three selected sites. Our results show that these three sites have different degrees of hazard due to their geological differences. The mean volume …

Os-Walk-Eu: An Open-Source Tool To Assess Health-Promoting Residential Walkability Of European City Structures, Stefan Fina, Christian Gerten, Brian Pondi, Lorraine D'Arcy, Niamh O' Reilly, David Sousa Vale, Mauro Pereira, Samuele Zilio

Articles

Introduction This paper introduces OS-WALK-EU, a new open-source walkability assessment tool developed specifically for urban neighbourhoods and using open-source spatial data. A free and open-source tool, OS-WALK-EU is accessible to the general public. It uses open data available worldwide and free online services to compute accessibility, while at the same time allowing users to integrate local datasets if available. Based on a review of existing measurement concepts, the paper adopts dimensions of walkability that were tested in European city environments and explains their conceptualization for software development. We invite the research community to collaboratively test, adopt and use the tool …

Image-Data-Driven Deep Learning For Slope Stability Analysis, Behnam Azmoon

Dissertations, Master's Theses and Master's Reports

Landslides cause major infrastructural issues, damage the environment, and cause socio-economic disruptions. Therefore, various slope stability analysis methods have been developed to evaluate the stability of slopes and the probability of their failure. This dissertation attempts to take advantage of the recent advancements in remote sensing and computer technology to implement a deep-learning-based landslide prediction method.

Considering the novelty of this approach, this dissertation leads with proof-of-concept studies to evaluate and establish the suitability of deep learning models for slope stability analysis. To achieve this, a simulated 2D dataset of slope images was created with different geometries and soil properties. …
