Teaching

  •  Soil Ecohydrology and Physics (SOIL 433/633), Fall of odd years.
    • This class introduces how things move in the soil and how that movement changes in time. Physical, chemical, and biological feedback mechanisms are discussed. All assignments provide students with real-world examples and case studies of how to use the concepts and computations as a professional practitioner working in the private sector. An introduction to Hydrus-1D with example problem sets is provided.
  • Advanced Soil Hydrology and Physics (SOIL 763), Spring of even years.
    • This class covers the theoretical and philosophical arguments that have been developed in the discipline, including the yet-to-be-resolved issues. The purpose of the class is to challenge students to deduce what is correct and what is complete in the mathematical-based theories of water flows in the vadose zone. In doing so, student will be able to discern the shape of the scientific community’s current knowledge. All assignments provide students practice with articulating these arguments.

Ongoing research projects

  • Remote sensing of soil moisture to extend weather mesonet stations representation
  • Plant survival in harsh storm-water systems such as rain gardens
  • Agricultural water management via tillage and cover crop systems
  • Slope failures in North Dakota
  • Natural, hydrophobic capillary barriers
  • Plant and soil responses to hexacycanoferrate
  • Occurrence and economic costs of deep wheel-traffic compaction

Past research projects

  • Brine spill remediation
