Adjusting the water flow rate in a river can prevent invasive species from moving upstream and expanding their range. An applied mathematician at UT has developed a partial differential equation model to find the desired flow rate to reduce invasive populations.

The model is detailed in a new paper by Suzanne Lenhart, Chancellor’s Professor and James R. Cox Professor of Mathematics, published in Mathematics.
