New publication on using flow partitioning to improve biogeochemical predictability

Monday, April 15, 2019

New work by Ecohydrology Research Group members has been published in the Water Resources Research journal. The article, titled "Can Improved Flow Partitioning in Hydrologic Models Increase Biogeochemical Predictability?", highlights the importance of considering flow paths in catchment-scale biogeochemical modeling of agricultural basins.

In this study, the authors present a calibration methodology for constraining the flow from tile drains, which was applied to a nitrogen model for an agricultural basin in southern Ontario. The authors demonstrate that utilizing tile flow data in their model improves the predictability of nitrate loads, and therefore, recommend that this approach be used for biogeochemical modeling of tiled landscapes.
