Professor and Department Chair,
geomorphology, environmental geology
I teach courses in physical geology, geomorphology, and environmental geology. My current research interests include temporal and spatial variations in drainage basin water and sediment yield and the associated downstream adjustments. The general objective of this research is to understand causative mechanisms for stream deposition, stability, or erosion, especially with respect to climate change. I am presently working on alluvial fan evolution in the Buena Vista valley of north central Nevada. This work compliments previous work in southeastern California and southwestern Montana and will culminate in a review paper on the influences of climate on alluvial fan evolution. I am also working on the causes of local drainage pattern changes in the Mad River and Little Miami River systems as they relate to the formation of Clifton Gorge and other gorges in the region. I joined the Wittenberg faculty in 1990.
