Effects of Urbanization on Stream Flashiness in the I-85 Corridor of the Southeastern Piedmont

The metro areas of the southeastern Piedmont are rapidly expanding, bringing changes to the hydrology of the watersheds within them. Increased urbanization can have significant effects on stream hydrology within a watershed, including large fluctuations of flow in streams referred to as “stream flashiness”. Increased stream flashiness has numerous consequences, including water quality degradation, flooding, and destruction of aquatic habitats. This thesis quantifies stream flashiness in urban and rural streams and investigates the relationship between flashiness and watershed land cover, particularly the amount and spatial distribution of impervious surfaces. Results show a strong relationship between urbanization and peak flows, but indicate that the underlying geology and other natural/anthropogenic factors complicate the relationship between R-B index and percent impervious surface cover. Results also indicate regional patterns within the southeastern Piedmont, most notably flashier streams in North Carolina compared to Georgia

This paper is concerned with the affective power of light, darkness, and illumination and their role in exposing and obscuring processes of rapid urban change. Little academic attention has focused on how lighting informs multiple, overlapping, and intersecting urban temporalities and mediates our experience of an ever-changing city. This paper foregrounds a walk through the illuminated city at night as an epistemic opportunity to develop an embodied account of material and temporal change in ways that disrupt the aesthetic organisation of the sensible world at night. By detailing the discontinuous experience of walking through differently lit spaces, the paper develops novel ways of conceptualising the experience of urban change that unsettle common understandings of subjectivity, temporality, and the city. The paper draws on a single night's walk from Canning Town to Canary Wharf in east London – an area that has recently undergone rapid change, including the erection of enclaves of high-rise development. By accentuating the shared experiences of walking with light, we reveal the affective capacities of light and dark to conceal and expose wider material, embodied, and temporal urban changes but also how we might challenge the organisation of the nocturnal field of the sensible

Moving through a dappled world: the aesthetics of shade and shadow in place

© 2019, © 2019 Informa UK Limited, trading as Taylor & Francis Group. In addressing geography’s neglect of shade and shadow, this paper explores how the dynamic play of shadow and light constitutes an integral part of everyday affective and sensory attunement to place and guides pedestrian movement. First, we identify how particular shadows are shaped by distinctive kinds of solar radiance, material forms, human visual perception and cultural representations. We then consider the different cultural ways in which shade and shadow have been interpreted across space and time and identify diverse shadowy effects in different geographical contexts. Thereafter, we focus on particular key elements of central Melbourne’s shadow aesthetics, discuss how patterns of shade guide urban choreographies, and explore how architects have imaginatively manipulated shadow
