Research Interests

To investigate and develop new knowledge on infiltration, overland flow, erosion and erosion mitigation techniques in disturbed forest and rangeland conditions and develop predictive models and decision support tools for use by land managers and playing in the dirt.

Past Research

• Developed relationships on the proper moisture content needed for prescribed fires to prevent increased or accelerated erosion and devised an electronic tool to measure that moisture content for instantaneous readings in the field
• Measured post-fire erosion rates and developed predictive models for post-fire erosion rates and effectiveness of selected mitigation treatment
• Summarized the current knowledge of fire effects on hydrology and erosion in numerous publications and books for use by land managers

Why This Research is Important

Erosion is a natural process; however, past management activities have caused degradation of water quality in numerous watersheds throughout various landscapes. Therefore, we develop tools and information to help managers make better decisions based on today's and future climates for improved management of our natural resources as well as impacts on life and property. Our tools and results are used by post-fire assessment teams, land management agencies, private interests, tribal and state governments. Considerable outreach has extended our knowledge usage to Europe, Australasia and South America.
