Following a call from Linton (2010) to think more relationally about water this thesis seeks to explore the infolding and unfolding relations that take-form between bodies around particular characteristics of freshwater. There is a tradition of exploration regarding the sustainability, quality, monitoring and management of water when we encounter research on human associations with fluvial hydrology, and whilst this work is important, this project looks to enrol more nascent and contemporary geographical themes to broaden our understanding of encounters with freshwater landscapes, and take a more relational approach to fluvial geographies. These works then shall address a gap in the geographical literature and describe the personal, pre-personal and affective worlds that emerge when bodies become down by the river. Whilst this is not specifically a walking project, walking the course of the River Severn serves as a trajectory along which processual ideas of bodies on the move shall be mobilised. A series of creatively written segues will link together a sequence of theoretical and conceptually driven site ontologies (Marston et al 2005; Woodward et al 2010) and relations associated with the Severn and freshwater more broadly. The flow and form of the thesis will reflect the multivariant characteristics of water and its varying speeds and slownesses. The chapters will step into puddles, mooch about in a ships graveyard, rethink the source of a river, paddle a coracle and set the scene for how an ontological, relational approach to fluvial landscapes can contribute to geographical thinking. The works will focus on human-nonhuman relations, vibrant materialities and elemental mobilities, in so doing enable further understanding of how we can apprehend sites as moments of coherence in a turbulent world, and contribute to broadening our scope of knowledge of the more-than-human.

Cities in the global South are confronting unprecedented challenges to urban sustainability and equitable development, particularly in the realm of water provision. Nearly 1.5 billion people worldwide suffer from a lack of safe access to drinking water and sanitation -an increasing proportion of whom reside in cities. Meanwhile, in the gaps of the grid, a diversity of water harvesting and reuse techniques, infrastructures, and institutional arrangements has emerged to provision poor households. Despite the burgeoning presence of the informal water sector, little is known about its institutional character, environmental impact, or relationship with state provision and private supply. Drawing on qualitative and quantitative data collected during nearly 13 months of fieldwork in Tijuana, Mexico, this dissertation queries how informal water use is managed, whether informal water use constitutes an alternative economy and sustainable environmental practice, and to what degree informal water use redefines urban space and alternative development possibilities. Findings reveal that: 1) despite historical efforts in Mexico to federalize and centralize the control of water resources, state action opens 'gaps' in the hydrosocial cycle, and informal institutions manage these 'extralegal' spaces; 2) informal water use is widespread across socioeconomic levels in Tijuana, predominantly managed by household-based institutions, and conserves a surprising degree of municipal water; and 3) the spatiality of contemporary water infrastructures and economies is highly diverse-ranging from bottled water markets to non-capitalist, self-provisioning greywater reuse-and is in fact constitutive of 'splintered urbanism' and alternative modes of development.
