Brighenti, Gassman publish in Journal of the ASABE

Postdoctoral Researcher Tássia Mattos Brighenti and Research Scientist Phil Gassman published in the most recent issue of Journal of the ASABE. Brighenti and Gassman authored the article "Comparison of Two Tile-Drain Methods in SWAT via Temporal and Spatial Testing for an Iowa Watershed" with Jeffrey Arnold of the USDA-ARS Grassland Soil and Water Research Laboratory and Jan Thompson of Iowa State's Department of Natural Resource and Ecology Management. The article investigates the application of two different SWAT tile-drain calculation methods (empirically and physically-based) in simulating the streamflow of the Des Moines River Basin and finds both empirical function and physically-based methods have satisfactory model performance for monthly and daily calibration (NSE > 0.5; KGE > 0.6; Pbias < ±25%).
