I develop flood models to simulate how flooding occurs in communities. We can use these models to create libraries of inundation maps or to identify potential flood mitigation projects. The information ultimately allows communities to evaluate and reduce flood risk. I am also involved in the Iowa Watershed Approach project. I develop digital watershed models that simulate how rainfall is transformed into stream flow. We use these watershed models to develop a hydrologic assessment to better understand where runoff is being created and what practices can be implemented to reduce runoff.
