Hydrogeomorphology studies river dynamics, focusing on the interactions between flow structure, sediment transport, and the morphologies that characterize rivers and their watersheds. It provides an analytical framework and tools for better integrating knowledge of river dynamics into river management in the broadest sense, and more specifically, into river restoration as well as into the assessment and prevention of risks associated with fluvial hazards. In Quebec, hydrogeomorphology is emerging as a significant contribution to risk assessment and management approaches, and is at the heart of a paradigm shift in river management whereby process restoration aims to increase the resilience of fluvial systems and societies, and improve the quality of fluvial environments. This contribution outlines the trajectory of hydrogeomorphology in Quebec, based on scientific publications by Quebec geographers, and discusses the discipline's aims in research and knowledge integration for river management.

Research on social housing stigma has proliferated due to growing concern over the effects of territorial stigmatization. The stereotyping of social housing as a site of ill-health, criminality, and low human capital stems from empirically ambiguous narratives created and recirculated through popular modes (e.g., social media platforms, news coverage). This paper combines principal component analysis, k-means cluster analysis, and geographic information systems to create and visualize clusters denoting different levels of health, crime, human capital, and dwelling composition in the city of Toronto, Canada. The quantitative research design allows for the identification of “asymmetries,” which are census tracts or neighbourhoods assigned to clusters indicative of high social housing density, and one of either sound health, low crime, or high human capital. The results reveal a spatial patterning of asymmetries in the inner city West End and Downtown, and in inner suburban North York, Etobicoke, and Scarborough. Overall, the paper illustrates the need to assess the empirical foundations of social housing stereotypes. Critically assessing stereotypes is important as they belie the rationale for social housing residents' living situations; pathologizes their identity, behaviour, and home; and generates public support for neoliberal solutions that displace long-term residents from their communities.

The article is a critical review of the literature investigating the impact suburbanization has had since the mid-20th century on the downtowns of Canadian mid-size cities and the strategies deployed to revitalize these districts. It demonstrates that large city downtowns are more likely than their mid-size city counterparts to enjoy conditions favourable to their success, hence the need to devise revitalization efforts tailored to the reality of mid-size city downtowns. The article identifies revitalization strategies adopted over the last decades, which mostly failed to reverse the decline affecting these downtowns. It then concentrates on the present, and likely enduring, revitalization model, which emphasizes hospitality, recreation, culture, services, and walkability. The article refines the understanding of the differences between mid-size and large city downtowns by concentrating on their specific dynamics and explores future revitalization options for mid-size city downtowns. It discusses the present and likely enduring absence of alternatives to the present revitalization model and highlights its equity downsides as it challenges the downtown low-income resident living environment.

Large-scale transit projects, such as light rail, are transformational for cities due to their ability to attract investment, curb sprawl, and intensify urban areas. In part because of enhancements to the public realm and improved connectivity, areas along new transit lines witness significant growth and investment, making them less affordable for residents already there. However, very little research has examined experiences of transit-induced gentrification, particularly at the early stages of a new transit project. The purpose of this article is to document these experiences from the perspective of those living along the planned LRT corridor in Hamilton, Ontario. Importantly, our research was conducted before construction started. Through in-depth interviews with residents living within 800 m of the planned LRT route, we found disparate experiences of change and ongoing housing affordability concerns on an individual, neighbourhood, and city scale. Many Hamilton residents express a need for more community engagement and transparency in the decision-making process. We detail these experiences and offer policy recommendations to inhibit further housing insecurity and displacement in light of the LRT development.

Surface-based temperature inversions (SBIs) are frequent and strong in valleys of north-central Yukon, which drive annual average surface lapse rates that are strongly inverted (≤1.19°C 100 m⁻¹) within the first 100 to 150 vertical meters. This study aims to test the relationship of SBI breakup with local microclimate factors determining the influence on surface lapse rate breakup patterns. A field study was conducted using elevational transect analysis. SBI breakup in the non-winter season had a strong relationship between the diurnal cycle of increased solar radiation, warming of the surface, and development of atmospheric turbulence in the form of increased wind speed. SBIs during these non-winter seasons had a peak breakup time of 4 to 8 h following sunrise. Wintertime SBIs often persisted past the diurnal cycle and broke up independent of solar radiation, contributing significantly to the inverted average surface lapse rates. Mechanisms of SBI breakup during the winter are likely more synoptic in nature and one possible mechanism could be shallow cold air flows. Current classification of SBI duration as persistent or transient was reviewed and adjusted, and SBIs with a duration of 18 to 22 h were removed due to the breakup of those events being related to the diurnal cycle.
