Freshwater Science: Understanding and (Potentially) Mitigating the Impacts of Tile Drainage

March 22, 2023 – Applied research from Ohio Sea Grant, Stone Lab and the Harmful Algal Bloom Research Initiative

Recent research from across the Midwest shows that with drainage water management, which uses tile drainage to control and adjust water flow from fields, annual nitrogen loads in field runoff can be reduced by as much as 50% while increasing crop yields. A similar result might be possible for phosphorus, with can fuel harmful algal blooms in Lake Erie.

Dr Steve Lyon at The Ohio State University is examining how this tile drainage impacts other water flow in agricultural fields, to better understand overall runoff and nutrient flows.

About the Speaker

Steve Lyon
Steve Lyon Associate Professor, School of Environment and Natural Resources, The Ohio State University

Dr. Lyon’s research uses innovative approaches to characterize hydrological processes and engage people across scales to improve resource management in the face of coupled climate and land-use change. He works at the intersection of water chemistry and hydrometric observations often leveraging geographical information systems, remote sensing products, and geostatistical approaches. Integral here is working with hydrological and natural resources models for hypothesis testing connected to real-world data. Dr. Lyon attended Purdue University and graduated with a BSc in Agricultural and Biological Engineering. He completed his MSc and PhD both in Biological and Environmental Engineering at Cornell University looking at how we incorporate the spatial structure of shallow water tables into hydrology. Dr. Lyon continued with postdoctoral research at the University of Arizona focusing on the evolution of land-water interaction in space and time. He joined the Department of Physical Geography at Stockholm University in 2008 promoting to Full Professor in 2016. While maintaining this affiliation, Steve worked with The Nature Conservancy as a Freshwater and Conservation Scientist. Dr. Lyon joined the faculty in the School of Environment and Natural Resources at The Ohio State University in 2019 as an Associate Professor in Hydrology and Water Resources.
