Water Luncheon Seminar

Removing microcystins from our water, a study to identify toxin-degrading bacteria in Ohio lakes

Xiaozhen Mou, Associate Professor; Department of Biological Studies, Kent State University; http://drosophila.biology.kent.edu/users/xmou/

WHEN: October 15, 2014;  11:30 am – 1:00 pm

WHERE: Wilma H. Schiermeier Olentangy River Wetland Research Park, Heffner Building, Columbus, OH (map)


An increasing number of freshwater lakes in Ohio and worldwide are invaded by cyanobacterial harmful blooms (CyanoHABs). One important harmful effect of CyanoHABs is the production and releasing of dangerous doses of cyanotoxins, mainly microcystins. Microcystins are highly hepatotoxic and have been reported to cause acute and chronic liver cell damage in livestock and human.  See full abstract here.

Ohio River Basin Climate Change Project

James Noel, Service Coordination Hydrologist/Meteorologist; NOAA, National Weather Service,  www.weather.gov/ohrfc/.

WHEN: July16, 2014;  11:30 am – 1:00 pm

WHERE: Wilma H. Schiermeier Olentangy River Wetland Research Park, Heffner Building, Columbus, OH (map)


The Army Corp of Engineers (USACE) Great Lakes and Ohio Valley division (LRD) along with the Huntington District (LRH) created a pilot project to analyze climate change in the Ohio Valley. In 2011 a group of agencies developed a project called Ohio River Basin Climate Change (ORBCC) project to identify what adaptations may be necessary based on hydrologic climate changes.  See full abstract here.

Water Luncheon Seminar

Assessing the Impact of Increased Climate Variability and Land Use Change on the Water and Nutrient Budget of the Upper Walnut Creek: Downscaling Climate Models to Drive Watershed Models

Gaj Sivandran, Assistant Professor, Civil, Environmental and Geodetic Engineering, The Ohio State University, http://ecohydrology.wordpress.com/

WHEN: April 16, 2014;  11:30 am – 1:00 pm

WHERE: Wilma H. Schiermeier Olentangy River Wetland Research Park, Heffner Building, Columbus, OH (map)


Non-point source pollution causes millions of dollars each year in impairment to surface waters in the United States, the largest contributing source being from agricultural runoff.  Due to the complex coupled process interactions within the biogeochemical and hydrologic cycles, the spatial and temporal extent of non-point source pollution can be difficult to assess and quantify.  See full abstract here.

Soil and Water Conservation Society Winter Meeting

All Ohio Chapter of the Soil & Water Conservation Society Winter Meeting & Conference

“Can Agriculture Significantly Reduce Off-Site Movement of Soluble Nutrients?”

Monday, March 17, 2014 – 8:30 am to 4:40 pm

Ohio Department of Agriculture – Bromfield Auditorium

8995 East Main Street; Reynoldsburg, Ohio


The emphasis of the presentations at this year’s conference will be discussing technologies and techniques to reduce off-site movement of nutrients and the barriers to their adoption and implementation. This conference is open to any conservation and agriculture professionals interested in reducing the off-site movement of nutrients.

This daylong event has been pre-approved for Certified Crop Advisor Continuing Education Units in the following categories: 5 hours of Soil & Water Management and 1 hour of Nutrient Management.  For more information on the agenda, cost, and registration, view the meeting flyer.

Green-Gray Decentralized Detention Infrastructure to Control Combined Sewer Overflows

Combined sewer overflows (CSO) are uncontrolled and untreated discharges of wastewater into urban streams that occur when the capacity of the collection system or the treatment facility are exceeded during heavy rainfall or snowmelt events.  Resilient and affordable solutions are needed to control CSOs and help manage urban flooding and improve water quality.  Typically, Gray infrastructure (i.e. sewers and treatment facilities) are proposed to mitigate CSO impacts.  A more environmentally friendly approach called Green  infrastructure (i.e. bio-infiltration, green roofs, rain gardens, etc) is being considered to solve this problem.  Interest has grown in using a combination of “green” and “gray” infrastructure because it not only mitigates CSOs, but also maximizes social, economic, and environmental benefits.  A unique framework that combines state-of-the-art mathematical modeling complemented with Geographical Information Systems (GIS) was developed to assess a non-conventional “green” and “gray” infrastructure alternative, composed of short storm sewers (gray) that  convey stormwater runoff into small decentralized detention ponds (green).  The detention ponds release the captured runoff back into the existing sewer at a constant rate controlled to  prevent the occurrence of a  downstream CSO.  The proposed framework includes methods to calibrate a high resolution rainfall-runoff model, identify potential sites for small detention ponds, and produce control-operation policies.  Results show that the green-gray infrastructure alternative is feasible and provides a higher CSO reduction at a lower cost than a conventional “gray only” alternative for a typical rainfall year.  The framework provides a useful promising tool for evaluating effectiveness, feasibility, and operation-control of this alternative in urban areas to reduce CSOs.
