The 2016 Kent State Water and Land Symposium

A major focus for the Watershed Hydrology lab this fall has been preparing for the Kent State University Water and Land Symposium. Anne Jefferson was the symposium co-chair (with lots of help from Biology’s Chris Blackwood), and all of the lab members were involved in some way. Pedro, Laura, Hayley, and Cody presented posters. Caytie and Garrett helped with set up and were on tweeting duty. The symposium had about 400 attendees from universities, agencies, cities, non-profits, and the general public from throughout northeast Ohio. If you missed the event live or on twitter, here’s how it went down.


This year’s symposium occurred on October 5-6, 2016, and featured the theme of “Sustainability and Resilience on the Land-Water Continuum.”

Green infrastructure research featured on Kent Wired

Kent Wired, the electronic version of Kent State University’s student media, ran a story on Saturday about the work Kimm Jarden and I have been doing on the effectiveness of green infrastructure retrofits in a neighborhood in Parma, Ohio.  Hopefully I’ll have more to say about this in the next few days. In the meantime, if you want a glimpse of what we’ve been up to, you can check out the news article here.

Kent State Water Symposium Tomorrow: Water Infrastructure and Rebounding Cities

Water Infrastructure and Rebounding Cities

Oct. 31, 2014

8 a.m. – 5:30 p.m.

Kent State University Hotel and Conference Center
215 Depeyster Street, Kent, OH 44240

Tomorrow will be a day full of inter-disciplinary talks and discussion about water and cities. David Sedlak, author of Water 4.0, will be the keynote speaker, but all of the talks promise to be informative and thought-provoking. Watershed hydrology lab students will be showing off their posters in the late afternoon.

Join us for this wonderful and stimulating event. For more info:

Watershed Hydrology Trip to Susquehanna Shale Hills Critical Zone Observatory

Kent State University Department of Geology’s Watershed Hydrology class visited the Susquehanna Shale Hills Critical Zone Observatory on April 5-6, 2014. Penn State post-doc Pamela Sullivan gave them a tour of the watershed and its instrumentation, with a focus on how the measurements could contribute to understanding how hydrology drives landscape evolution on shales. The students were introduced to the challenges of hydrologic field work as they attempted to produce a continuous flow of water from a 75′ foot deep well on the watershed’s ridgeline. On Sunday, the students learned and practice water quality sampling protocols and collected water samples from streams and shallow wells in the CZO watershed and in watersheds with differing geology.Temperature, pH, specific conductance, and DO were measured in the field, and ions, cations, and stable isotopes will be measured in laboratories at Penn State and Kent State. The students will discuss these data in class over the next several weeks as they integrate their understanding of how geology and topography control hydrologic flowpaths, streamflow generation mechanisms, and water quality.

The class stayed on the shores of Lake Perez, which has been drained for the last few years to enable repairs on the dam. The lake has just begun refilling, but while empty it has created some interesting research opportunities.

Kent State students enjoyed seeing a mostly empty reservoir. It’s neat to be able to see a dam, spillway, and what the reservoir bottom looks like without any water.

Pam Sullivan describes the well field at Katie Creek. This area will soon be inundated by the refilling of Lake Perez. Some wells are being raised up, so that Penn State scientists can assess the effects of the reservoir refilling on local groundwater dynamics.

I’ll try to add some more beauty shots of the CZO watershed at some point, but I wanted to be able to show our class in action in the field.

Sensitivity of precipitation isotope meteoric water lines and seasonal signals to sampling frequency and location

Allison ReynoldsThis work is being conducted by undergraduate lab member, Allison Reynolds. Allison presented her work as part of the CUAHSI/USGS Virtual Workshop on applications of laser specs to hydrology and biogeochemistry. From that workshop, she will have an extended abstract published in a USGS open file report, and her poster will continue to be viewable on-line. She will also be presenting results at the inaugural Kent State Undergraduate Research Symposium in April. And of course, she’s going to keep working on new data and analyses and aiming for publication. Go Aly!

Our purpose is to compare seasonal signal and local meteoric water line (LMWL) generated by analyzing hydrogen and oxygen isotopes in precipitation for one year of event-based sampling to those from multi-year monthly sampling at the closest Global Network of Isotopes in Precipitation (GNIP) stations. The question we seek to answer is whether data from different sampling strategies, periods, and locations within the eastern Great Lakes region on a regional-scale LMWL and seasonal signal. We collected precipitation samples after each event in Kent, OH. Samples were analyzed with a Picarro L-2130i. The closest GNIP sites are Coshocton, Ohio and Simcoe, Ontario. LMWLs and seasonal signals derived from monthly samples were broadly similar along a 300 km north-south transect in the US eastern Great Lakes Region. Monthly volume-weighted averages of event precipitation under-represent event scale isotopic variability, based on samples from Kent, Ohio.

REU at Kent State – Come work on aquatic-terrestrial linkages in urban ecosystems

Kent State and Holden Arboretum are hosting a summer REU (Research Experience for Undergraduates) focused on aquatic-terrestrial linkages in urban impacted ecosystems. Lots of great faculty in geology, biological sciences and other departments are participating, and I would be thrilled to mentor a student through the program. The program will run from June 1st to August 8th, 2014, and applications are due February 17th.

Kent State University and The Holden Arboretum invite applicants for a 10-week summer research training program. Students enrolled in this program will conduct mentored research into the importance of terrestrial-aquatic linkages in the ecology of urban-impacted ecosystems. This research will be designed to examine how human activities such as urbanization, industry, farming, mining, and recreational activities affect the way terrestrial and aquatic ecosystems interact. Projects might compare sites with and without urban impact to examine: nutrient cycling in soils and streams, microbial community composition in forest soils and stream sediments, plant-soil interactions, how shredders modify terrestrial leaf litter input to stream ecosystems, the effects of terrestrial pollutants on aquatic microbial community structure and function, how terrestrial and aquatic biogeochemical cycles are affected by human activities such as acid precipitation and land-use change. Along with learning about hypothesis generation, project design, and ethics in research, students will receive additional training archiving data in a geospatial database and will participate in weekly seminars.

To find out more about the program, look at all of the possible mentors and cool projects, and begin the application process, check out the website here.

Resources for Kent State students

Students in the College Teaching of Applied Geology class did an amazing job of compiling a list of on- and off-campus resources that may be of use for undergraduate and graduate students in the department. Please check out the list here. There is also a university prepared list of on-campus resources available here. And if you need help, don’t hesitate to ask in the Geology Departmental Office in 221 McGilvrey Hall or by phone at 330-672-2680.
