A conceptual model of diagonal bar evolution Damia Vericat and I developed and have started to test on rivers in Spain.
Status Update (Oct, 2019): This project was unfortunately not funded in FY19. I am still seeking funding for it. We had a stellar crop of over-qualified applicants for a Fall 2019, but were unable to secure the studentship support from a handful of interested agencies.
If you are a prospective graduate student looking to apply for Fall 2020 start, I am still keen to fill this position, but will be unable to do so unless I successfully find grant funding or you can secure fellowship funding. If you are a prospective student, and are able to secure your own studentship, tuition and research support funding, please get in touch with me.
If you are an organization (e.g. agency, NGO, etc.) interested in partnering on this important research and have ideas for funding this research, please get in touch with me.
UNTIL I HAVE SECURED FUNDING, I am not actively seeking graduate students on this project, but happy to field questions and inquiries. My apologies.
I am seeking a Masters or PhD Student to shed light on diagonal bar dynamics. Diagonal what? Diagonal bars are by far the most common mid-channel bar throughout the world's rivers and streams, yet many people have never heard of them. Diagonal bars split flow around themselves in a characteristicallyasymmetrical fashion, creating complex in-channel habitat and leaving behind distinctive islands and floodplain topography. Diagonal bars start their lives as margin or bank attached bars on the inside-bend of flow, but then proceed to detach from the bank via a process of chute cutoff formation along the inside bend. They seem to evolve through a similar progression in extremely different fluvial environments. Diagonal bars are an excellent geoindicator of river-health in many reach types (e.g. wandering gravel bed rivers) as they often disappear when lateral adjustment is artificially confined. Basic empirical data on diagonal bars, their occurrence, their evolution and their prevalence is largely lacking from the geomorphic literature and restoration practitioners are largely unaware of their importance. This student would work with myself and Damia Vericat to build-out, refine, and rigorously test a conceptual model of diagonal bar evolution we developed, and build important insights into this poorly understood but pervasive bar form.
