ACTIVE & PASSIVE HYDROLOGICAL RESTORATION

A recent article in Coastal Review (a service of the North Carolina Coastal Federation) about the possibility of “farming carbon” in peatlands of northeastern North Carolina via carbon sequestration and trading and carbon trading markets caused me to revisit some work from my younger days—a frequent diversion for old codgers like me. Many of the pocosin wetlands were artificially drained by ditches and canals sometime between the 18thcentury and the 1980s, and the key to maximizing carbon sequestration there is restoring the wetland hydrology. Back in the 1980s I did some work on artificially drained peatlands in the region, and in the 1990s on other artificially drained farmland in eastern N.C. One of the bottom lines was that this is a case where passive restoration works. In other words, if you simply don’t maintain the ditches and canals, they rapidly lose conveyance capacity and essentially become linear ponds. In some contract work I did for the Croatan National Forest in N.C. in 1997, in fact, I recommended passive restoration—there was no need to fill in canals or remove water control structures, etc.

FOR PEAT'S SAKE . . . .

In the lower reaches of some coastal plain rivers there is a transition from mineral to organic alluvial soils, which appears to mark the leading edge of effects of sea-level rise. This post is part of project to address the question of how a river, swamp, or floodplain undergoes a transition--apparently relatively suddenly in some cases, judging from stratigraphy--from a muddy or sandy, mineral-dominated state to one that is overwhelmingly composed of organic matter? For background, see this previous post. 

 

MUCKING AROUND IN THE SWAMPS

As rivers flowing across the coastal plains of the Carolinas approach the coast and their estuaries they widen, split into multiple channels, and flows can slow or reverse as astronomical tides, wind tides, and storm surges downstream have their effects. And on their floodplain swamps, the sandy and muddy soils and sediments give way to organic mucks or peats.

NEW YEAR, NEW STRATH TERRACES

Fluvial (river or stream) terraces are former active floodplain or channel surfaces that become isolated from regular flow or inundation by downcutting (incision) of the channel. Alluvial terraces start as predominantly depositional floodplains, but as the river incises, they eventually become isolated from flooding and deposition in all but the largest, rarest floods. Strath terraces are erosional surfaces associated with former channel positions; again, separated from river flows by downcutting of the channel.

2023 Panelists

Katie Brown received her degree in Geography with a minor in Biology from the University of Kentucky in May of 2020. During her time in Lexington, she had developed an interest in the interplay of health and space, which continues to guide her work today. Currently, Katie is a Ph.D. Student in the Department of Geography, Environment, and Spatial Sciences at Michigan State University. Since joining the program in the Fall of 2021, Katie has contributed to multiple research projects, attended major conferences, and had the chance to work in the field collecting various forms of data. While still in the formative stages, Katie’s intended dissertation involves assessing how urban transformations impact residents’ mental health. She plans to look at the case of Detroit, MI, where many legacy residents may be affected by the rapid physical and social neighborhood-change occurring. Upon completing her degree, Katie hopes to stay in a university setting and contribute to research surrounding health equity.

Sean Conway is an Orthoimagery Technical Expert with NV5 Geospatial, graduating from UK Geography in 2014. Using the tools and techniques he learned during his time at UK, he advanced to his current position overseeing large scale imagery projects. On Twitter and Instagram: @geo_spatialist. 

Amanda Curry works as a Compliance & Operations Staff member in the ​Director's Office of the Energy and Environment Cabinet of Kentucky. She grew up in Kentucky in Woodford County on a family farm where her curiosity and love for the environment began. Curry originally attended UK from 2000-2002, but left to begin a family and worked in a variety of administrative capacities. In 2018, she had the opportunity to return to UK to finish her degree. She was the 2020 ENS Outstanding Senior and graduated with honors (magna cum laude) with bachelor’s degrees in both ENS and Geography, with minors in Appalachian Studies and GIS/Mapping. She currently works as an Environmental Scientist II in the Division of Enforcement with the Department for Environmental Protection at the Kentucky Energy and Environment Cabinet and she is excited about the work I am currently doing, mostly in relation to wastewater compliance monitoring, and the projects that I will be working on soon including dam safety, environmental justice, and a variety of GIS projects.

Sam Harmon graduated UK in December 2019 with a Bachelor’s in Environmental and Sustainability Studies as well as a Bachelor’s in Political Science. In the Fall of 2020, he began law school at the J. David Rosenberg College of Law here at UK. He has also accepted a post-grad associate attorney position at Porter, Banks, Baldwin & Shaw, PLLC, right here in Lexington where he plans to continue his legal career in civil litigation with a focus on insurance defense.

"Guides for Queer Folks: Travel Guides, Maps, and Materiality"

Borrowing from scholarship in map studies, critical cartography, queer media studies. and critical bibliography, this talk examines the utility of queer geographic information as expressed through its materiality. Through an examination of queer spatial information from the 1930s to the mid-2000s—primarily travel guides and maps but also magazines, postcards, and advertising—this talk explores two main arguments. Firstly, that the physical arrangement of queer spatial media and the work individuals undertook to collect, circulate, protect, and keep up to date this information in the pre-digital era reveals this information's politics and perils. Secondly, the presentation argues that to understand these social currents there is a need for renewed attention to physical media and physical interaction during the archival research process. The talk concludes by examining the presenters’ efforts in developing an archival collection of queer spatial information.
