Confluences
This collection of poems, essays, and fictional stories is meant to mirror a confluence of rivers, made navigable by threads—or currents—that weave through and redirect my life. Some of my life’s water (so far) has been brackish. Some of it is clear. To use a bit more concretion, as they say, the …

Numerical, field and laboratory studies of three-dimensional flow structures at river channel confluences
… flow structures at river channel confluences. Previous work has shown that junction angle is an important control on the flow patterns at channel junctions since it affects the degree of curvature of flow from each tributary and sets up secondary circulation cells similar to those …

A River of Voices: Confluences and Cross-Currents in the Discourse of the Colorado River
This dissertation argues that the Colorado River and its watershed face a crisis of representation as privileged nineteenth-century myths portraying the American West as a frontier, garden, and wilderness have limited an understanding of what and whom the river is for. It examines the contribution …

Moving beyond the stream reach: Assessing how confluences alter ecosystem function and water quality in freshwater networks
… avoid complex geomorphology such as stream confluences. As a result, the impact of stream confluences on in-stream ecosystem processes and the fate of carbon and nutrients in freshwater networks has been overlooked. In this dissertation, I seek to address the following questions: (1) How are …

"As It Flows Down from the North": Confluences of Water Stewardship Emerging from the Ottawa River Watershed
… of 2016, this research describes how localized confluences of people, institutions, technology and non-human species are responding to assembling ecological pressures by configuring new approaches to Ottawa River watershed stewardship. I explore how such confluences constitute the …

On creating cleantech confluences : best practices and partnerships to mobilize multiple sources of private capital into early-stage clean technologies
During the 2015 Paris Climate Change Conference, world climate scientists and policymakers agreed that global temperatures must not exceed a two degree Celsius increase above pre-industrial levels within the next 30 years. It is estimated that this will require investments of $40 trillion or $1.3 …

Measuring flow and mixing at stream confluences using large-scale particle image velocimetry, in-stream techniques, and small unmanned aerial systems
Confluences, locations where two rivers flow into one another, are characterized by the mixing of water, dissolved nutrients, chemicals, pollutants, and sediment. The process of mixing at confluences is inherently related to patterns of confluent flows, yet the complex nature of confluence …

Satellite remote sensing of mixing dynamics at a large river confluence
… remotely sensed images of rivers downstream from confluences, no systematic methodology has been developed for assessing mixing over distance of confluent flows with differing suspended sediment concentrations. In contrast to field measurements of mixing below confluences, remote-sensing data can …

High-resolution spatial and temporal evolution of two-dimensional flow structure at a small stream confluence
Confluences are recognized as locations within rivers where interaction between incoming flows produces complex hydrodynamic conditions characterized by distinct spatial patterns of mean or turbulent flow. Despite recognition of this hydrodynamic complexity, few studies have mapped in detail …

The impact of dams, droughts, and tributary drainages on channel form and process : Rio Grande and Rio Chama, NM
… change were partly controlled by tributaries confluences. To examine tributary controls along the Rio Chama, elevation and bed sediment data were collected at 200 cross sections situated up and downstream of 26 tributary confluences along a 17 km reach situated just upstream of Abiquiu …

Rates and patterns of temperature mixing at a small stream confluence under variable incoming flow conditions
River confluences are locations in the fluvial network where two incoming flows, often with distinct chemical, thermal, and physical properties, converge and start to mix. The degree of mixing that occurs within a confluence influences ecological and water quality conditions locally as well as …

The fluvial dynamics of confluent meander bends
… sediment transport, and bed morphology at river confluences. Previous experimental, field, and modeling studies of confluence dynamics have focused mainly on junctions formed by straight approach channels that meet at angular configurations before entering a straight receiving channel. In …

Light streams in again
… The narrator tells his own story through the confluences and patterns formed in the tangling of personal and impersonal cycles, particularly patterns of decay, loss and maturation. Simultaneously, the collection meditates on, and blurs, the lines between his narrative, the narratives of family …

Zooplankton, Macroinvertebrate, Herpetile, and Ichthyofaunal Biodiversity of Riverine Habitat on the Upper Missouri River
… main channels, sandbar complexes, tributary confluences, and vegetated islands. Zooplankton sampling consisted of replicate vertical tows with a plankton net. Macroinvertebrate sampling included a petite ponar dredge for the benthos as well as dipnet smapling. Additionally, the molluskan …

The University Experiences of Post-9/11 Native American Veterans: Strategic Support For Inclusion, Retention, & Success
… and transitioning into higher education. The confluences of situations and circumstances often determine the ability of Native American Student Veterans to engage, persist, and complete their academic endeavors; therefore, support systems are vital in helping them navigate and overcome …

Breaking my silence as a 'trained' dancer in post-apartheid South Africa
