A Closer Look #178

New Postdoctoral Researcher at AWRI

Dr. Lidiia Iavorivska joined AWRI in July 2017 as a postdoctoral research associate in Dr. Al Steinman’s lab. Lidiia graduated from the Pennsylvania State University with a Ph.D. degree in Forest Resources in December 2016. Her doctoral research focused on evaluating to what extent the chemical composition of rainwater has potential to influence nutrient cycling in terrestrial and aquatic ecosystems. Specifically, her dissertation characterized the variability of organic carbon inputs from precipitation over space and time, bringing attention to atmospheric deposition of organic carbon as an underreported but quantitatively important piece of the carbon cycle on both global and regional scales.

Lidiia will be working on using a Soil and Water Assessment Tool (SWAT) hydrologic computer model at AWRI to help inform land management decisions to reduce pollutants into local water bodies. She is currently working on modeling the Lake Macatawa watershed. By combining modeling tools with water quality data that are being collected by AWRI, she will be able to evaluate how land-use decisions (such as different agricultural practices or stream and wetland restoration projects) can influence stream and lake water quality, as well as which of these practices are the most effective in solving water quality problems. The model for the Lake Macatawa can serve as a decision support and assessment tool for an ongoing Project Clarity, which collaborates with local communities in the watershed on implementing best management practices that will reduce the amounts of phosphorous and sediments that are delivered from the land into the lake.
