Modeling – Predicting water quality (IMAGE) DOE/Oak Ridge National Laboratory Caption An ORNL research team has incorporated important effects from microbially active hot spots near streams into models that track the movement of nutrients and contaminants in river networks. The integrated model better tracks water quality indicators and facilitates new science.
