Biography

I am a professor in the Department of Geography & Earth and Environmental Science at Okanagan College in Penticton. My interests are focused around hydrology and soils, specifically forest hydrology and green roof hydrology. I have a wide range of forestry-related hydrology and soil science experience in coastal, montane and boreal environments in BC and Alberta. Past employment includes as an Earth Science Research Technician with the BC Ministry of Forests and a Watershed Management Extension Specialist withFORREX. I am a Professional Agrologist registered with the BC Institute of Agrologists.

I am a former editor of Streamline Watershed Management Bulletin (http://forrex.org/publications/streamline) and was project coordinator and co-editor of The Compendium of Forest Hydrology and Geomorphology in British Columbia (http://www.for.gov.bc.ca/hfd/pubs/docs/lmh/Lmh66.htm) a comprehensive reference text on the hydrology, geomorphology and aquatic ecology of forested watersheds in BC.

Research Interests

My research interests are related to hydrology and sustainable watershed management. My background is largely in the study of forested watersheds. I have research interests the areas of snow hydrology, runoff generation, soil physics and the effects of forest management and natural disturbance (e.g., wildfire, mountain pine beetle) on watershed processes. I am also working on stormwater management and green roof hydrology at the OC Penticton campus.

 

My current research activities include involvement with the Upper Penticton Creek Watershed Experiment (http://www.for.gov.bc.ca/rsi/research/Penticton/index.htm) in collaboration with scientists from the BC Ministry of Forests, University of Lethbridge, Simon Fraser University and the University of Saskatchewan.

 

Other current research includes the application of inexpensive temperature sensors to measure changes in temperature with elevation across the Okanagan Valley at Penticton. This data is valuable for modelling hydroclimatic processes at the local and regional scale. With Robin Pike (BC Ministry of Environment, Victoria, BC) I am working on improving calibrations and identifying the range of suitable conditions for a simple and inexpensive instrument for determining stream velocity (transparent velocity head rod).

 

I am keen to talk to enthusiastic OC students about the potential for directed studies projects (GEOG 298). In the past I have worked with students on projects related to snow hydrology and geology.
