Research Interests
My research interests focus on a variety of topics with the theme
"water". Interests include ground water, streams, snow, and water
quality. Active projects include evaluation of contamination of ground
water below rural subdivisions from a physical, microbiological and
geographic information perspective; assessment of the potential of the
Madison aquifer for Bozeman city water supply, development of a
Geographic Information System (GIS) based risk assessment for nitrate
and microbial contamination of ground water in the Gallatin Local Water
Quality District; and development of a conceptual hydrologic model for
one or more wildlife refuges in the Morthern Rocky Mountain region. I
am interested in research topics such as GIS models of the spatial
distribution of clay-mineral type and irrigation-suitability of water
produced during development of coalbed methane, the relationship
between slope roughness elements in streams and stream morphology, the
relationship between slope geomorphology and channel form, the
processes of snowmelt production and runoff prediction, development and
validation of models which predict snow hardness using GIS, assessment
of snow avalanche potential in mountain settings, and geothermal
hydrogeology of the Yellowstone region.
