Newly-funded Project Investigates HABs in the Upper Ohio River Basin

We’re eager to get started on a newly funded, 3-year, ~$700K grant by the U.S. Environmental Protection Agency (EPA), as part of its Science to Achieve Results (STAR) program. Our project focuses on nutrient enrichment and harmful algal blooms (HABs) in Ohio River catchments of Ohio, Kentucky, and Indiana, with a particular focus on non-agricultural freshwaters. This research is in collaboration with Drs. Lauren Pintor and Kai Zhao.

Specifically, we propose to develop a watershed classification system to diagnose and manage harmful algal blooms (HABs) in the upper Ohio River basin. The goal is a multi-scale, hierarchical tool that links climate and land-use with river physicochemical gradients and ecological condition to predict and prevent HABs. The resulting classification system will be presented in a framework that can be used by managers as a regular part of watershed planning and risk assessment efforts to prevent and predict HABs. This management tool represents a novel application of theoretical knowledge of hierarchical processes in watersheds and an innovative approach to predicting and managing HABs.

Conceptual model of relationships to be tested and used to develop multi-scale, hierarchical management tool.
