CONSULTING ACTIVITIES

My primary consulting activities are in the areas of environmental data analysis, design of experiments, and hydrology. Some recent assignments include: sampling design and statistical data analysis for environmental effects monitoring, hydrologic and hydraulic analysis for flood risk mapping, low flow frequency, duration, and dry spell analysis for small hydro development, and low and high flow frequency analysis for Peter's River, Newfoundland.
