Understanding Changes To Human Mobility Patterns In Ontario, Canada During The Covid-19 Pandemic, Ben Klar
Understanding Changes To Human Mobility Patterns In Ontario, Canada During The Covid-19 Pandemic, Ben Klar
Electronic Thesis and Dissertation Repository
Transportation research has shown that socio-demographic factors affect people’s mobility patterns. During the COVID-19 pandemic, some of these effects have changed in accordance with changing mobility needs adapting to the pandemic, including restrictions on in-person gatherings, closure of in-person businesses and working from home. We investigate two gaps in current knowledge in this area of transportation research: to what extent the association between socio-demographic factors and mobility metrics have changed, and how these associations vary across geographic space. We also investigate how closely Ontario’s Public Health Unit boundaries, based on which pandemic restrictions were applied, reflect actual travel regions, and …
Measuring The Morphologic Response Of Braided Rivers To Lateral Constriction, Victoria Barlow
Measuring The Morphologic Response Of Braided Rivers To Lateral Constriction, Victoria Barlow
Electronic Thesis and Dissertation Repository
The aim of this thesis is to understand the morphologic changes to a set of historically braided rivers that have been narrowed. Braided rivers from the agriculturally developed Canterbury Plains, New Zealand, were studied from a period prior to much development (mid-1900s) to the present. Narrowing of channels, decreased braiding intensity, and loss of braided planforms were determined based on aerial imagery, changing the geography of braiding along all rivers. Channel width and count were statistically correlated and show the predictability of braiding change based on narrowing. Reaches with initially wide channels require more narrowing to induce a simplification of …
